Be aware that even using ini_set to set 'magic_quotes_runtime' will stop working in PHP 5.4. See http://php.net/manual/en/info.configuration.php#ini.magic-quotes-runtime

You should NEVER rely on magic quotes or addslashes for security in an SQL context. You should ALWAYS use proper escape functions, such as mysql_real_escape_string. Failure to do so may result in an SQL injection vulnerability.

A simple check and disabling of magic quotes whenever needed (e.g. if you deploy to multiple servers or you don't know the target server's PHP version).
<?php
if(version_compare(PHP_VERSION, '5.3.0', '<')){
set_magic_quotes_runtime(0);
}
?>

get_magic_quotes runtime and set_magic_quotes_runtime are useful when you want to read some data in a binary file using fread() and some bytes in such file may be interpreted as \ (backslash), " (double quotes), ' (simple quote) or any "special" character that has a meaning for string processing.
