Note Submitter: rohankumar dot 1524 at gmail dot com ---- 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
