Php_self

<FORM METHOD="POST" ACTION="<? echo $_SERVER['PHP_SELF']; ?>">


if i have this code in my CallerFile.php
is it similar to
<FORM METHOD="POST" ACTION="CallerFile.php">
???

if not may i know the differences
if yes which is better?

sujith

Yes it's the same
$SERVER['PHP_SELF'] is a superglobal which contains the page which is opened.
So in your case : if you visit callerfile.php
$SERVER['PHP_SELF'] will automaticly get the url visited, so in this case it will contain : /callerfile.php

This variable is usefull when you create installscripts. If people then install your script in the directory 'newscript/'
you should change your link of every form to /newscript/callerfile.php but with the $server['php_self'] it automaticly posts to the page /newscripts/callerfile.php


I hop this is clear because i'm not a good explainer

Shouldn't that be $_SERVER['PHP_SELF'] (i.e. dollar underscore …)

yes sorry forgot to typ it lol
