I'm working on an old site, written by somebody else, and they've done something equivalent to extract($_POST) somewhere in there code. But they didn't use the function extract.
The application was originally designed for PHP3 (yes, old), then it was ported to PHP4, and now I'm porting it to PHP5.
Does anyone know of what function it could be? Or, any way of finding it out? I've tried using PHPStorm's 'GoTo -> Declaration' but that wasn't it....
I've scanned the documents for the variable and there is no other reference to it, so its being generated by a function equivalent to extract.
It may be the register_globals setting. Check the php.ini file on the server and see if it's turned on. If it's on you should turn it off and make all the necessary changes to the code to fix it (as part of your porting to PHP 5).
Another relevant page after checking the other link in this post: http://php.net/manual/en/security.globals.php
May be used something like this:
foreach ($_POST as $key => $value)
{
${$key} = $value;
}
