In the interests of writing portable code (code that works
in any enviroment), or, if you do not have access to change
php.ini, you may wish to disable the effects of magic quotes
on a per-script basis. This can be done in two ways, with a
directive in a .htaccess file (php_value magic_quotes_gpc 0),
or by adding the below code to the top of your scripts.
<example>
<title>Disabling magic quotes at runtime</title>
<programlisting role="php">
<![CDATA[
<?php
if (get_magic_quotes_gpc()) {
$_POST = array_map('stripslashes', $_POST);
$_GET = array_map('stripslashes', $_GET);
$_COOKIE = array_map('stripslashes', $_COOKIE);
}
]]>
</programlisting>
</example>
Magic-quotes was added to reduce code written by beginners from being dangerous.
If you disable magic quotes, you must be very careful to protect yourself from
SQL injection attacks.
