What is the replacement for the deprecated mysql_real_escape_string() function in PHP 5.5.0 and beyond?

Deprecation of mysql_* Functions in PHP 5.5.0 and Beyond

In the transition from PHP 5.2.0 and earlier to PHP 5.5.0, you may encounter difficulties with deprecated mysql_* functions. The mysql_real_escape_string() function, deprecated in PHP 5.5.0, has been replaced by mysqli_real_escape_string() in the mysqli extension.

Error and Resolution:

You are receiving the error "Deprecated: mysql_real_escape_string(). To resolve this, replace the function call with mysqli_real_escape_string($connection, $escapestring)." The mysqli_real_escape_string() function requires two arguments: $connection and $escapestring.

Modified Code Snippet:

<code class="php"><?php

$username = mysqli_real_escape_string($connection, stripslashes($_POST['username']));
$password = mysqli_real_escape_string($connection, stripslashes($_POST['password']));

?></code>
Copy after login

Here, $connection represents the established connection to the MySQL database.

Additional Notes:

  • Consider using a database object to simplify connection handling.
  • Refresh your PHP knowledge to stay up-to-date with deprecated and updated functions.
  • For further information, refer to the official PHP documentation on mysqli_real_escape_string().
