How to get part of the line after !sen? After !sen may be any value from the letters/digits and examples:
1. !senword
2. !sen123
3. !senword123
I'm doing
```
$sen = explode("!sen", $s);
```
But what's the fastest way?

If I understood your question correctly, you could use your function. http://php.net/manual/ru/function.substr.php

<?php
/**
 * В данной функции параметр $fromChar не обязательный,
 * по умолчанию он указывает на позицию символа после которого
 * нужно будет вырезать строку, он пригодится в том случае
 * когда Вы решите отбросить не !sen а допустим !se или !senw
 */
function foo($string, $fromChar=4)
{
    return substr($string, $fromChar);
}
// ну и проверка
echo foo('!senword'); // выведет word
echo foo('!sen123');  // выведет 123
$testString = foo('!senword123', 3);

echo $testString; // выведет nword123

?>

The problem is that in the search function you do not need to recover the search criterion, nor do you re-write the SQL instruction. If you look well, the instruction builds on index.php, only is there to recover the search criterion from the _$REQUESTI mean, it would be doing this in index.php :}elseif(isset($_REQUEST["buscar"])){ $busqueda=$_REQUEST['busqueda']; $con=conexion("localhost", "root", "", "articulos"); buscar($con, "SELECT * FROM articulos WHERE nombre LIKE '%$busqueda%'"); cerrar($con); } And in funciones.phpmodify the method as follows:function buscar($con, $sql){ $resultado=mysqli_query($con, $sql); while($fila=mysqli_fetch_array($resultado, MYSQLI_ASSOC)){ echo "Código de producto: " . $fila['codarticulo'] . "<br> "; echo "Nombre del producto: " . $fila['nombre'] . "<br> "; echo "Precio de compra: " . $fila['pc'] . "<br> "; echo "Precio de venta: " . $fila['pv'] . "<br> "; echo "Cantidad de stock: " . $fila['cantidad'] . "<br> "; echo "Tipo de procucto: " . $fila['tipo'] . "<br> "; echo "<hr>"; } } NÓTESE that I have changed the parameter MYSQLI_BOTH a MYSQLI_ASSOC. Because the first one brings you the data twice, like associative and numerical array, which reloads memory, bringing data you won't use.On the scope of the variablesIn your initial mistake you seem to think that by the simple fact of including fuciones.php already. $busqueda would be visible in index.php. In PHP the variables are local in scope, that is, they exist only within the functions where they are declared. If in any file you declare a variable within a function, if you try to use it outside it will tell you that the variable does not exist, even if you are in the same file.SecurityYour code is vulnerable to attacks SQL injection. A bad user intentional could take control of your system by manipulating maliciously variable as $busqueda that you pass to execution direct. Consider using queries prepared to prevent this risk.

Try this:struct Matrix{ static constexpr int base = 5; int a[base][base]; }; bool operator<(const Matrix &left, const Matrix &right){ for(int line = 0; line < Matrix::base; ++line){ for(int column = 0; column < Matrix::base; ++column){ if(left.a[line][column] != right.a[line][column]){ return left.a[line][column] < right.a[line][column]; } } } return false; } Matrix are compared to the first different element.If necessary, we can also remove the other operators:bool operator>(const Matrix &left, const Matrix &right){ return right < left; } bool operator==(const Matrix &left, const Matrix &right){ return !(left < right) && !(left > right); } bool operator!=(const Matrix &left, const Matrix &right){ return !(left == right); } bool operator>=(const Matrix &left, const Matrix &right){ return !(left < right); } bool operator<=(const Matrix &left, const Matrix &right){ return !(left > right); } UPD Mistake invalid comparator comes when you come. operator<() not in accordance with the regulations http://en.cppreference.com/w/cpp/concept/Compare ♪ You can check that:Matrix a; a.a[1][0] = 1; Matrix b; b.a[0][1] = 1; Matrix c; c.a[0][1] = 2; //false std::cout << std::boolalpha << (a < a) << std::endl; //true false std::cout << std::boolalpha << (a < b) << " " << (b < a) << std::endl; //true true true std::cout << std::boolalpha << (a < b) << " " << (b < c) << " " << (a < c) << std::endl; http://rextester.com/YHJED27691

Calm down, everyone has failures, especially during learning. Sometimes it's better to rest and get back to the problem with a fresh head.If we figure out what's wrong with the code:♪ $_POST No field. submite.g. <input type="submit" value="Загрузить файл!"> No attribution name="submit"enctype="multipart/form-data" means like, Browser sends data, not which and how muchWe need to build some files. input c type="file" and unique name (laughs) name="arr_name[]")What do we have in the end?<form name="Download" id="Download" method="post" action="so.php" enctype="multipart/form-data"> <input type="number" name="run" value="run"> <input type="file" name="file1"> <input type="file" name="file2"> <input type="file" name="file3">   <input type="submit" name="submit" value="Загрузить файл!">   </form> And consistent with this, we're getting at the conclusion(I downloaded files: exmaple.js, package-lock.json and test.html):Array ( [run] => 123 [submit] => Загрузить файл! ) Array ( [file1] => Array ( [name] => exmaple.js [type] => text/javascript [tmp_name] => /tmp/phpADCPPN [error] => 0 [size] => 765 ) [file2] => Array ( [name] => package-lock.json [type] => application/json [tmp_name] => /tmp/phpqG2ipe [error] => 0 [size] => 15311 ) [file3] => Array ( [name] => test.html [type] => text/html [tmp_name] => /tmp/php5UiNYE [error] => 0 [size] => 658 ) )

One thing could do, for example, https://stackoverflow.com/a/36230031/4827341 :sed ':a;N;/\n[^a-zA-Z]/s/\n/ /;ta' файл It's not gonna work until the project interpreter works. gnu♪:a - it's a name mark. aN - add the symbol of the new line at the end pattern spaceand then finish the next line from the input flow/\n[^a-zA-Z]/s/\n/ / - general synthesis: /шаблон/команда♪ команда to be implemented for lines appropriate шаблону\n[^a-zA-Z] - an integral template: the symbol of the line translation, then the symbol corresponding to the template [^a-zA-Z]i.e., " not the Latin alphabet "s/\n/ / - team. sthe replacement symbol for the transfer of the line to the gapta - Conditional transition (if last completed) s Substitution) aprevious version proposed by me:sed ':a;N;/\n[^a-zA-Z]/s/\n/ /;ta;P;D' файл There were two other teams that I thought I'd take away as unnecessary:P - in this case. pattern spaceD - in this case, pattern space and start a normal new cycle (to process the next line from the input flow).What's your mistake?sed "N;${rn}s/\n//g" The following will be read first in the processing of the next line (thanks) Nand will be processed номер-строки команда (the gap is only for visuality, usually not used in this place, although the gap is quite correct.)What's the logic for your case and the cycle when you're in. $nr I'll be there. 4The interpreter program will look like: N;4s/\n//gI'll start with the line number one. N) Considered and followed, condition not fulfilled (line number 1, this does not correspond to the figure indicated 4)Line 3 will be processed immediately, followed by it, but the condition will not be fulfilled again: the row has number 3, and this again does not match the figure. 4Line 5 will be further processed and followed, but no replacement will be made.The file was over.How can you fix your (satisfactorily long and slow) option? N Relocate the unit inside. sYes and the modification g You can clean it up, it's out of here:sed "${rn}{N;s/\n//}" rows will now be read in series, without " passes " , the additional line will be counted only once when the row is processed with the number to be inserted from the variable envelope ${rn}♪

I recommend using you Socket. http://socket.io/ . It is very simple, this example connects to twitter and issues an event every time you find a new user tweet. It sounds interesting to implement it with the Youtube API.var io = require('socket.io')(80); var cfg = require('./config.json'); var tw = require('node-tweet-stream')(cfg); tw.track('socket.io'); tw.track('javascript'); tw.on('tweet', function(tweet){ io.emit('tweet', tweet); }); Greetings.

None of the dates used by you guarantee the unambiguous translation of the textual submission of the date into type. date or datetime♪I suggest that when exporting to csv or xml ISO format YYYYMMDDwhich, in any SQL Server, will be interpreted explicitly regardless of language lines.The following design can be used to translate to the ISO textual submission: convert(varchar, DateColumn, 112)Details can be read https://docs.microsoft.com/ru-ru/sql/t-sql/functions/cast-and-convert-transact-sql

The visibility of the variable $api is a function getNewsList(). If you need to get a variable elsewhere, you need to put it in a separate method that will bring it back. In News class, create a methodpublic static function getApi() { $api = '123123123'; return $api; } And call where you need it.$api = News::getApi();

std::set not checking the elements uniquenessand check the elements equivalence♪ Equivalence is defined through the comparison function you have set. If your comparison fountain says the input element. equivalent Someone already present in the container will not be inserted. Whether or not this element is equal to or not (in terms of literally stored data) is irrelevant.In this case, you wrote a comparison function that says all elements with equal values in the fields. second.first equivalent. That's what caused your behavior.

There is no method within the other, there is a sequence of methods.With the object servicecalls the method getImageKeywords() passing some arguments. It will produce a result (generally the methods return something), this result is an object that can invoke other methods, in the case is invoking the execute() in the object returned by getImageKeywords(). The result of execute() is that it will be stored in the variable keywords.This code could be written like this (or almost, I used https://pt.stackoverflow.com/q/47383/101 , which does not yet have in Java, because I do not know the type of method):var temp = service.getImageKeywords(image, forceShowAll, knowledgeGraph); ImageKeywords keywords = temp.execute(); More visible example:public static void main (String[] args) { String x = teste().toString(); //teste retorna um inteiro 42 que é usado pelo toString System.out.println(x); //x já é uma string "42" } public static Integer teste() { return 42; } See https://ideone.com/PfDGN1 . And https://repl.it/join/tndccswn-maniero . Also https://github.com/maniero/SOpt/blob/master/Java/Syntax/Methods.java .One thing people don't usually realize is that variables serve to keep intermediate values. There are cases that are necessary, or at least more advantageous, but not always they need to be used. An intermediate value of an expression can be used direct where necessary without the use of a variable.An expression is usually composed of sub-expressions that produce intermediate values. Pure math.
