mysql_escape_stringEscapes a string for use in a mysql_query


This function was deprecated in PHP 4.3.0, and it and the entire original MySQL extension was removed in PHP 7.0.0. Instead, use either the actively developed MySQLi or PDO_MySQL extensions. See also the MySQL: choosing an API guide. Alternatives to this function include:


mysql_escape_string(string $unescaped_string): string

This function will escape the unescaped_string, so that it is safe to place it in a mysql_query(). This function is deprecated.

This function is identical to mysql_real_escape_string() except that mysql_real_escape_string() takes a connection handler and escapes the string according to the current character set. mysql_escape_string() does not take a connection argument and does not respect the current charset setting.



The string that is to be escaped.

Return Values

Returns the escaped string.


Example #1 mysql_escape_string() example

"Zak's Laptop";
$escaped_item mysql_escape_string($item);
printf("Escaped string: %s\n"$escaped_item);

The above example will output:

Escaped string: Zak\'s Laptop



mysql_escape_string() does not escape % and _.

You can use this function safely with your MySQL database queries if and only if you are sure that your database connection is using ASCII, UTF-8, or ISO-8859-* and that the backslash is your database's escape character. If you're not sure, then use mysqli_real_escape_string instead. This function is not safe to use on databases with multi-byte character sets.

The only benefit of this function is that it does not require a database connection.
