I would recommend avoiding `$_SERVER['PHP_SELF']`. it is very easy to inject malicious data by simply appending `/ – reinierkors Jun 07 '17 at 12:05

either you can use php_self or the page name directly. – Niladri Banerjee - Uttarpara Jun 07 '17 at 12:08

Do you mean to use either `PHP_SELF` or `example.php` based on some condition? – k32y Jun 07 '17 at 12:12

If you want to submit your form to the same page, i.e. PHP_SELF when a condition is met and submit it to example.php when a different condition is met, then try this:
<form method="POST"
action="<?php echo $some_condition == "some_value" ? $_SERVER['PHP_SELF'] : 'example.php' ?>">
...
Your form content here
...
</form>
You will replace $some_condition == "some_value" with whatever condition you want to check.

`session_start()` has to be called before you print any output to the screen. if possible let it be the first statement in your script. You are getting that error probably because your script threw an error somewhere and the error message is printed before your `session_start()` statement is executed. – k32y Jun 08 '17 at 08:55
