<para>
Returns a string with backslashes stripped off.
(<literal>\'</literal> becomes <literal>'</literal> and so on.)
Double backslashes (<literal>\\</literal>) are made into a single
backslash (<literal>\</literal>).
</para>
<para>
An example use of <function>stripslashes</function> is when the PHP
directive <link linkend="ini.magic-quotes-gpc">magic_quotes_gpc</link>
is <literal>on</literal> (it's on by default), and you aren't inserting
this data into a place (such as a database) that requires escaping.
For example, if you're simply outputting data straight from an HTML
form.
</para>
<para>
<example>
<title>A <function>stripslashes</function> example</title>
<programlisting role="php">
<![CDATA[
<?php
$str = "Is your name O\'reilly?";
// Outputs: Is your name O'reilly?
echo stripslashes($str);
?>
]]>
</programlisting>
</example>
</para>
<note>
<para>
<function>stripslashes</function> is not recursive. If you want to apply
this function to a mutli-dimensional array, you need to use a recursive function.
