Un-quotes a quoted string.

<note>
<para>
If <link linkend="ini.magic-quotes-sybase">magic_quotes_sybase</link> is
on, no backslashes are stripped off but two apostrophes are replaced by
one instead.
</para>
</note>
<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.

Double backslashes (<literal>\\</literal>) are made into a single
backslash (<literal>\</literal>).
