note 126329 added to function.mysql-real-escape-string

There is requirement for old projects which are using mysql_escape_string, and upgrading the PHP version to 7 and above. Basically this happens in maintenance projects where we don't know how many files the functions are used in application. We can use [mysqli.real-escape-string][1] for the function: If you have a typical connection file like conn.php $conn = new mysqli($host, $user, $password, $db); // may be few more lines to handle the $conn if (!function_exists('mysql_escape_string')) { function mysql_escape_string($sting){ // if mysql_escape_string not available return $conn->real_escape_string($string); // escape using the $conn instance } } [1]: https://www.php.net/manual/en/mysqli.real-escape-string.php ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 2409:4043:48b:2774:b8e7:c45a:9f76:62ad) ---- Manual Page -- https://php.net/manual/en/function.mysql-real-escape-string.php Edit -- https://main.php.net/note/edit/126329 Del: integrated -- https://main.php.net/note/delete/126329/integrated Del: useless -- https://main.php.net/note/delete/126329/useless Del: bad code -- https://main.php.net/note/delete/126329/bad+code Del: spam -- https://main.php.net/note/delete/126329/spam Del: non-english -- https://main.php.net/note/delete/126329/non-english Del: in docs -- https://main.php.net/note/delete/126329/in+docs Del: other reasons-- https://main.php.net/note/delete/126329 Reject -- https://main.php.net/note/reject/126329 Search -- https://main.php.net/manage/user-notes.php
