Suri for this headline, I'm looking for a string function where the function is looking for a match like this.
```
if (функция("текст","кс")) { $fun == true } else { $fun == false } в этом случае результат true
```
I was looking for php.su, but I didn't find a lot of functions.

After some time breaking the head (believing), I realized that I am actually overwriting the function by using the same name for the variable:var xyz = xyz(); Changing the variable name in this section, it worked correctly.It may seem like a stupid mistake, but somehow it took me a while, I hope it can help others not do the same.

Try to codify the page in UTF-8. I think the problem might be that. If there's no change in the page code, try the following:echo iconv('cp1251','utf-8',$_GET['first_name']); P.S. Between rawurldecode() and urldecode() the difference is almost nonexistent, except that the urldecode "plus" is decoded into a ruptured symbol.

You can use mpm_itk. Debian and Ubuntu have a package. For RHEL-based systems, Apache headline files can be presented and hands collected (the network has ready specs for this).

Option 1. Transpose the mass (change the first and second level keys). Maybe even with the numerical keys removed. I can see that you have an initial mass. $comments_arrhas duplicate information. For example $comments_arr['title'] the same thing as that. $comments_arr[0]♪ $comments_arr['content'] ♪ $comments_arr[1] etc. We'll get a more comfortable set with this structure:$comments_arr = [ [ 'title' => '...', 'content' => '...', 'date_1' => '...', ... ], [ 'title' => '...', 'content' => '...', 'date_1' => '...', ... ], ... ] With this volume, the code will be more visible and understandable:foreach ($comments_arr as $comment) { echo $comment['title'] . ' '; echo $comment['date_1'] . ' '; echo $comment['date_2'] . ' '; echo $comment['content'] . ' '; } Of course, it needs to be understood that the processing of the mass is an additional time, so this is a way to increase the visibility of the victim of optimization.Option 2. Leave the mass as it is, but check for all the fields to be needed (in case). When missing, it might be useful to record a warning.foreach($comments_arr['title'] as $key => $val) { if (!isset( $comments_arr['content'][$key], $comments_arr['date_1'][$key], $comments_arr['date_2'][$key] )) { // пропускаем записи, у которых нету какого-то из "полей" continue; } echo $val . ' '; echo $comments_arr['date_1'][$key] . ' '; echo $comments_arr['date_2'][$key] . ' '; echo $comments_arr['content'][$key] . ' '; }

There's no sign in Java. That's not gonna work. All awards can be said to be duplicated when they are transferred as parameters. They're in the execution stack and they can only be changed at their level of steak.

You want to make yourself a utilitarian object to create others. That's a factor.Formally, your object registrar He has no methods. It has keys whose value is a function. But you could put export default class Registro { static usuario(params) {...} static empresa(params) {...} } And it would be methods.Do not say if the invocation of the method to register a user sends a request, persists in a BBDD, modifies the DOM, etc. but do what you do, and for the most reason if you want to add logic to the created entity, That's not the right place..Factory can work as a record that knows which models are in the system, but it does not have to know the differences in the domain logic of each one when creating them. For example (apply to the regulation of your country),a user has social security number, the company has no such thing.a company has a VAT and a registration number in the trade conservative. A user has no such thing.The right thing (or a little more correct) would be to encapsulate the logic of users and companies in classes. With the user, for example:class Usuario { constructor(name) { this.name = name this.enabled = true } disable(flag) { this.enabled = !flag } } In your factory:class Registro { static usuario(...params) { return new Usuario(...params); } } With that, the following would leave a user instance in your variable newUser let newUser = Registro.usuario('Test') And by the way it would be perfectly valid to deactivate it "to the flight" with Registro.usuario('Test').disable(true) The bad thing is that it does not return a user, but you could make a small modification so that the methods that modify attributes of the instance return the instance itself. disable(flag) { this.enabled = !flag return this } And with that you could put: let newUser = Registro.usuario('Test') .disable(true) .disable(false) And your variable would still have a user instance.As you now want to add the method that disables it, you will want to add another method later. For example, to notify the user by mail. In order for that to make sense, it should also be used with an electronic mailclass Usuario { constructor(name, email) { this.name = name this.email = email this.enabled = true this.notify('Gracias por inscribirte') } disable(flag) { this.enabled = !flag return this } notify(message) { enviarUnCorreo(this.email, message).then(()=> console.log('enviado!')) return this } } And you could do, for example:let newUser = Registro.usuario('Test','test@mail.com') .disable(true) .notify('Te desactivamos ajajaj') Did you notice that I clarified your user factor using a spread parameter?static usuario(...params) instead ofstatic usuario(params) That was a reason to be, because After all the modifications we made about the User class, the factory has not changed at all. I didn't need to change it by the new method or the additional parameter.By a simple design decision, we save ourselves to modify the factory in the future whenever you change the logic of the created entities.

Unfortunately, in the first Yii, you can't just write that. It's connected to getParam:public function getParam($name,$defaultValue=null) { return isset($_GET[$name]) ? $_GET[$name] : (isset($_POST[$name]) ? $_POST[$name] : $defaultValue); } So first, we need to get RefMahala, and then we need to find a district_id.

To begin, it should be emphasized that include "http://sequrity.ru/config.php"; It's not gonna give you back the violin of the file you've been called, but it's a result of it.In this case, you can solve this problem in several ways. Use Git. This is the best way to solve this problem. Use NFS(Network File System) is a web-based file system that allows users to access files and catalogues located on remote computers, as if those files and catalogues were local. You're changing the file in one file to which both websites are online.The above-mentioned options will only help you if you have a dedicated server. But if it's not, you're probably going to sync these files manually. To begin with, these files need to be transmitted online in encrypted order to avoid leaking the original code. Besides, you need to determine when the files will be synchronized. This can be implemented as follows: On one server, you have a file. http://mysait.ru/get_encripted_file.php who returns the encrypted reference code and over the other website sync.php who accepts, decodes and retains it.Here's an example get_encripted_file.php /** * @param $string * @return string */ function encrypt($string) { $encrypt_method = "AES-256-CBC"; $secret_key = 'This is my secret key'; $secret_iv = 'This is my secret iv'; // hash $key = hash('sha256', $secret_key); // iv - encrypt method AES-256-CBC expects 16 bytes - else you will get a warning $iv = substr(hash('sha256', $secret_iv), 0, 16); $output = openssl_encrypt($string, $encrypt_method, $key, 0, $iv); $output = base64_encode($output); return $output; } $sourceCode = file_get_contents('file_for_encrypt.php'); echo $encryptedSourceCode = encrypt($sourceCode); And this is the synchronization code.php is exactly the violator that will roll the crypt, decode and preserve it./** @param $string @return string */ function decrypt($string) { $encrypt_method = "AES-256-CBC"; $secret_key = 'This is my secret key'; $secret_iv = 'This is my secret iv'; // hash $key = hash('sha256', $secret_key); // iv - encrypt method AES-256-CBC expects 16 bytes - else you will get a warning $iv = substr(hash('sha256', $secret_iv), 0, 16); $output = openssl_decrypt(base64_decode($string), $encrypt_method, $key, 0, $iv); return $output; } $sourceCode = file_get_contents('http://mysait.ru/get_encripted_file.php'); file_put_contents('save_to_this_file.php', $sourceCode);

You can write something like that:function domSelfClosedElement($name, array $attrs = []) { $attrs = array_map(function($val, $key) { return htmlspecialchars($key).'="'.htmlspecialchars($val).'"'; }, array_values($attrs), array_keys($attrs)); $attrs = implode(' ', $attrs); return "<$name $attrs/>"; } echo domSelfClosedElement("input", ['name' => 'username', 'type' => 'text', 'class' => 'form-control']);

I'd like to share my answer in three parts:If you just take your code and put it in the front lines. чебурек and монгол - He'll get out. чмеобнугроелк♪ I see that all the letters are present and some are, for example, о - more than once.You don't have any sortings in the code, so it's unsorted.In the case of formal injection, it is generally assumed that each element enters only once. Obviously, this function and the code just cannot work.Look, you've got i and j indices that are meant to run for two lines transferred.But you change them at the same time. You are.You don't know that you've reached the end of the shortest word. The increase in each index continues until the end of the long termYou don't want to see if there's an added element (or elements) in a multiplicity.A logical implementation would be:We're creating an empty-resulting lot.We're running the first line. For each letter of the first line, we add it to the resulting lots.For the second word, it's the same.Some of the code could look like this, (windows.h is used for the normal withdrawal of the Russian letters in code 1251, it can be dropped, but then it can't work with the salt, but only with the files, apparently)#include <iostream> #include <string> #include <algorithm> #include <windows.h> #include <fstream> using namespace std; // сюда переадется слово и стока, представляющая объединенноее множество символов. // так как пеердача просиходи по ссылке - я прямо здесь меняю это множество. // поэтому функция имеет тип void - возвращать из неё ничего не надо void add_word_and_sort(const string& src, string& dst ){ for( auto& ch : src ) if ( dst.find(ch)==string::npos ) dst += ch; sort( dst.begin(), dst.end() ); } string str_conjunction(const string& a, const string& b) { string c = {}; add_word_and_sort(a, c); add_word_and_sort(b, c); return c; } int main(){ SetConsoleCP(1251); SetConsoleOutputCP(1251); ifstream inp("input.txt"); string s1 , s2; inp >> s1 >> s2; string rez = str_conjunction( s1, s2 ); cout << rez << endl; } Actually, there's a standard container set. He's beautiful, and he's just shaking a lot of things.

The canonal answer to the basic question is https://learn.javascript.ru/function-expressions ♪Functions are important. They may be assigned, copied or declared elsewhere.If the function is declared as a separate instruction mainly for the flow of the code, it is Function Declaration.If the function was created as part of the expression, it is considered that this function is declared by Function Expression.Function Declaration is processed before the code unit is implemented. They're visible in the whole block.Function Expression functions are created only when the flow of performance reaches them.Additional questionvar abv=function abv() { return 3 }; console.log(typeof abv); // function Functions in JavaScript https://developer.mozilla.org/ru/docs/Web/JavaScript/Guide/Functions - The key concept in JavaScript. A critical feature Language is the primary support for functions (functions as first-class citizen). Any function is an object, and hence it. may be manipulated as a target

An ordinary generator ascii-art is represented. The algorithm of his work is approximately: the image is taken, the image is extended, converted into black and white, and the piccell values are then sharply taken - if it's black, then we figure 0 if white - 1 (or vice versa).In order to reverse the image: a mass is taken (if it is a row broken by the symbols of the row ' s portability, then a portable image is created, the size of the height in the volume of the mass, and the width is the length of the longest row and the image is 0 = black picsel, 1 = white

In fact, the second set of parameters is the second function of the returned first. Here.def sigma(x: Int, y: Int, z: Int, a: Int)(f: (Int, Int, Int, Int) => Double): Double = 1.0 def bigPi(x: Int, y: Int, z: Int, a: Int)(foo: (Int, Int, Int, Int) => ((Int, Int, Int, Int) => Double) => Double):Double = 3 bigPi(1, 2, 3, 4)(sigma) In fact, the question of an interesting, compiler is not dealt with in all cases, apparently because the functions of the highest order in the scale are represented through the map.
