$PHP_SELF Question

[seanmayhew]

Can somebody give me a one sentence answer for why I would use $PHP_SELF?

For instance :

action="<?php echo $PHP_SELF ?>"

Because php self points to itself.
So if you have hmm, say 4 pages that all php includes a search.php for example.

And you want to display results in same page, use a <?php echo $_SERVER["PHP_SELF"];?>

Otherwise you will have to change it for each 4 pages and have a search.php for each page.

search.php
<?php echo $_SERVER["PHP_SELF"];?>
end search.php

<?php echo $_SERVER["PHP_SELF"];?> == search.php

I use it because I have a file called functions.php which contains links to the rest of my site. I include that file in everyone of my scripts. Using $PHP_SELF just automatically puts in the link for whatever page I am already at. Its also handy in functions.

It is very useful for reusing code among other things.

I use it to consolidate add/edit/delete functions for a form into one page.

Example:

If I have a database table with articles, I can use one page to ADD/EDIT/DELETE Articles. All the forms just keep referencing itself and passing a $state variable, via HTML FORM's INPUT HIDDEN whose value is usually equal to add/edit/save/delete. If $state is blank then display and empty form with the state variable set to add.
