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 was on by default before PHP 5.4), 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.

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>).
