Formatization of chemical reactions on php

There are textual chemical reactions from the base, like:
Ce2(SO4)3 + (NH4)2S2O8 = 2Ce(SO4)2 + (NH4)2SO4
All numbers (including overlaps) need to be built (addition of html strategies) <sub>except for the numbers at the beginning of the line and after the gaps.
I tried to make a sedative, but it's kind of hard. I've been told that it's sort of a way to simplify or use a mass or regular expressions.preg_match) I found regular expressions how to make all the numbers straight, but I can't limit the sample.
How can we handle this line properly and rationally?

Thank you, splash58! In the end, the line was:
```
$formula = preg_replace("/(?<=[A-Za-z)\]])\d+(,\d+)*/","<sub>$0</sub>", $formula)
```
which makes line html with numbers in the form of substrate indices. The second option you proposed does not take two-digit numbers.

Here's a working decision. throw Exception may be replaced by another act, but if this action does not interrupt the cycle, you must use break or return.$config = [ 'name' => 'Название', 'db' => [ 'username' => 'root', 'charset' => 'utf8' ] ]; $get = 'db.username'; $path = explode('.', $get); $varable = $config; foreach ($path as $key) { if (!isset($varable[$key])) { throw new \Exception('Not found'); } $varable = $varable[$key]; } print_r($varable); // root This decision makes any difference. For example, if $get = 'db', then $varable will contain a mass [ 'username' => 'root', 'charset' => 'utf8' ]

I believe that this way will work, goes on functions.php and adds this code. add_action( 'wp_enqueue_scripts', 'enqueue_load_fa' ); function enqueue_load_fa() { wp_enqueue_style( 'load-fa', 'https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css' ); } Now just add the icons by text editor, like so<i class="fa fa-home fa-fw" aria-hidden="true"></i> Source: https://www.elegantthemes.com/blog/tips-tricks/font-awesome-wordpress Official Woocomerce Documentation about Font-Awesome https://docs.woocommerce.com/document/using-icon-fonts/ List of icons: http://fontawesome.io/icons/

php crypt - trailing dollar sign - extract only the salt part from hash - padding the salt

The 22 characters it requires are actually encoded binary data that is used for the salt. Bcrypt/Blowfish/$2y$ only uses the first 128 bits of your 132 bits, so the last four bits are totally ignored and should not be a dollar sign because that is not a valid character for the modified base64 encoding that is used for the salt. What has happened is you specified too short a salt, so it was padded with $ so the system knows the salt has ended. The reason it ends up being a . is because since only the first four bits are used, the last four are padded with zeroes before the beginning of the encoded hash. A . is all zeroes in this base64 type encoding and because there's no previous value to affect the first four bits of the 22nd character, you end up with just the .. As an aside it does make me wonder why they chose to use dollars instead of . to represent the missing salt - perhaps just to differentiate between actually asking for zeros in the salt and the automatic decision to pad with them. $pass = 'secret'; echo crypt($pass, '$2y$07$notlongenough'), "\n"; echo crypt($pass, '$2y$07$longenoughsortof......'); > $2y$07$notlongenough$$$$$$$$.uYiNG9WczQSWgnuPdcNj0jugGbSnaAC > $2y$07$longenoughsortof......9dPQFbAgDCQ4RWEcZ4/ficmGapMNSpC It only makes sense to provide one of: ., O, e, or u for the last character of the salt because these are the only characters in the encoding set that actually affect the first four bits. FYI the full range is [./A-Za-z0-9] in that order, so if you number them 0-63 and look at the binary expression of those numbers you'll see where those four characters come from. The examples seems to erroneously use trailing dollars. They are not needed and indeed shouldn't really be present. All you need to do is provide enough bits for the salt depending on the algorithm you're using. Every character should be as random as possible up until enough bits have been provided (i.e. a minimum of 22 characters for Blowfish/$2y$). The output is then a concatenation of: algo-description, salt used and hashed result/password. The algorithm knows the binary boundaries of where the salt ends and the hashed string begins. There should not be any dollar signs with $2y$ because you should have provided a long enough salt string which will not consist of any dollar signs (again, because that is not in the valid character range for the utilised modified base64 encoding). This should be enough information for you to extract the salt if you so desire. But PHP actually recommends the use of password_hash, as do I if you have v >=5.5.0 http://in1.php.net/manual/en/function.password-hash.php. This will automatically generate a secure random salt for you using either /dev/urandom or CryptGenRandom() on Windows - both well vetted to be sufficient for this purpose. If you've already started using crypt, password_hash is compatible so fear not about upgrading to use it.

In HTML, http://%20%20%20%20https:%20//developer.mozilla.org/es/docs/Web/HTML/Element/a , therefore, you must build a valid label that includes the property href And if you want a picture, you put it inside. <a> ... </a>.For example, here, the first two images have their link. If you have understood, it will not be difficult to link to the third image if necessary.<div class="top"> <a href=".\index.php"><img class="top__logo" src=".\img\menu\logo_best.png" /></a> <div class="top__rigth"> <a href=".\signIn.php" target="_blank"><img class="top__menu icon" src=".\img\menu\icon_menu.png"></a> <img class="top__menu login" src=".\img\menu\button_login.png" /> </div> </div>

The function FORMAT only accepts numerical types and date types. You could do this:DECLARE @cep int = 23574510; SELECT FORMAT(@cep,'#####-###') AS [CEP]

Request query It is necessary to indicate a little other way if you follow up on the request.Additional shielding may not be used in the request line itself.Also added the correct conclusion of the error information if the request was not implemented for any reason.In this case, you will see a mistake. If the request has been successful, the OBD information will be removed.<?php // возможность добавить записи в "новости" if (isset($_POST['title']) && isset($_POST['full_text'])){ $title=$_POST['title']; $full_text=$_POST['full_text']; } $db_host = "localhost"; $db_user = "root"; // Логин БД $db_password = ""; // Пароль БД $db_base = 'animals'; // Имя БД $db_table = "news"; // Имя Таблицы БД // Подключение к базе данных $mysqli = new mysqli($db_host,$db_user,$db_password,$db_base); $result = "INSERT INTO news (title,full_text) VALUES ('$title','$full_text')";//добавления записи т.е. запись в БД $res= mysqli_query($mysqli, $result); if (!$result) { die('Ошибка выполнения запроса:' . mysqli_error()); // Если ошибка, запроса, то выводим имя ошибки. } // Если ошибки нет, то выводим данные ?> If the request is to be sent only if both data are obtained.<?php // возможность добавить записи в "новости" if (isset($_POST['title']) && isset($_POST['full_text'])) { $title = $_POST['title']; $full_text = $_POST['full_text']; $db_host = "localhost"; $db_user = "root"; // Логин БД $db_password = ""; // Пароль БД $db_base = 'animals'; // Имя БД $db_table = "news"; // Имя Таблицы БД // Подключение к базе данных $mysqli = new mysqli($db_host, $db_user, $db_password, $db_base); $result = "INSERT INTO news (`title`,`full_text`) VALUES ('$title','$full_text')";//добавления записи т.е. запись в БД $res = mysqli_query($mysqli, $result); if (!$result) { die('Ошибка выполнения запроса:' . mysqli_error()); // Если ошибка, запроса, то выводим имя ошибки. } // Если ошибки нет, то выводим данные print_r($res); }

sedcommand-n -pUnless the option is specified, all the contents of the input file are displayed (output) regardless of whether the pattern is matched or replaced or not.andgrepThere is no "display/not display the matched file name" option like the command, so if you want to display the subst ted file in the result such as the question https://ja.stackoverflow.com/a/54991/3060 I think that it is necessary to narrow the target file before sed.

To your question of using this approach:Write the code to the receiving amount. radius goods; Write the code to the receiving amount. by firm;Write the code in the middle. price of goods by firm;Write the code for the 10th. Road goods;Make a price for the company's goods. Yokohama by 2.3%;etc. It may then be clear whether to leave such an approach or to use the OBD.

Add non-binding. GET- a metric for page indication, e.g. page♪ On the basis of this parameter and the number of records that you want to see on the page, define the derogations to the request for OBD:$offset = ($page-1) * $recordsPerPage; // если страницы нумеруем с 1 The number of pages depends on the number of records:$pagesCount = ceil($recordsCount / $recordsPerPage); Don't forget to put a record limit on the request for OBD equal $recordsPerPage♪

I recommend you to use absolute routes and as everything goes through index.php, there you can define a constant, using the https://www.php.net/manual/es/language.constants.predefined.php that returns the route to the disk of the current file.<?php session_start(); // Definir constante con directorio actual define('PROY_RUTA', __DIR__); require_once 'helpers/utils.php'; require_once 'autoload.php'; require_once 'config/Parameters.php'; require_once 'config/Database.php'; require_once 'views/layout/header.php'; require_once 'views/layout/sidebar.php'; Every one you need to include or save another file uses that constant:<?php function controllers_autoload($classname){ // Usa la constante para tener la ruta completa $script = PROY_RUTA . "/controllers/"$classname.php"; // Verifica que el archivo existe antes de incluirlo if(file_exists($script)) { include $script; } else { die("No existe el archivo de controlador para <b>$classname</b>."); } } spl_autoload_register('controllers_autoload'); Suppose you want to save a text file in assets/documents:$contenido = 'Esto se va a guardar en un archivo de texto'; file_put_contents(PROY_RUTA . '/assets/documents/archivo.txt', $contenido);

I think it's a little inappropriate to use regular expressions for this, and they're putting a lot of pressure on the system. $request = $_SERVER['REQUEST_URI']; //user/get/id/1 - так выгледит строка запроса $splits = explode('/',trim($request,'/')); //Выбор контроллера $this->_controller = !empty($splits[0])?ucfirst($splits[0]).'Controller':'IndexController'; //Выбор экшена $this->_action = !empty($splits[1])?$splits[1].'Action':'indexAction'; //выбор параметров if(!empty($splits[2])){ $keys = $values = array(); for($i=2,$cnt = count($splits); $i<$cnt;$i++){ if($i%2==0) $keys[] = $splits[$i]; else $values[]= $splits[$i]; } if($keys and $values) $this->_params = array_combine($keys,$values); } } Только тут ещё нужно сделать отслеживание если вдруг в строке нету какого нибудь экшена или контроллера.

What is addslashes for? It has no benefit against HTML injection as it does not remove the characters that are special to HTML. If it is meant as a protection against SQL injection it is ineffective, especially for non-MySQL databases that don't even use backslash as an escape in SQL string literals. You should exclusively use parameterised queries to get data into SQL queries without SQL injection problems. htmlentities is OK against injection into HTML text content and double-quoted attribute values. But: it doesn't escape ' so it will fail for single-quoted attribute values (add flags parameter ENT_QUOTES to fix) it assumes ISO-8859-1 character set so you will get broken output if you are actually dealing with something else like UTF-8 (add charset parameter to fix, or, probably simpler, use htmlspecialchars which leaves non-ASCII characters alone) HTML escaping is something you do when you are creating an HTML page. You need to htmlspecialchars() every piece of text as you drop into HTML because that's the point at which you know that the text needs escaping. Don't HTML escape input between receiving it and writing it to the database, this is completely the wrong time.
