$_server

[marain]

Partial output of

echo '<br />
<br />
<br />
$_SERVER
<br />
<br />
<br />';
foreach ($_SERVER as $bigkey => $bigvalue) {
echo "The value of $_SERVER $bigkey is $bigvalue <br />";
}

at http://www.njexpungements.com/test.php:

The value of Array REQUEST_URI is /test.php
The value of Array SCRIPT_NAME is /test.php
The value of Array PHP_SELF is /test.php

Presumably the three indicated elements are not interchangeable, but I can't see the difference.

Thoughts?

Mod's note: the forum software automatically makes words lowercase in order to prevent "screaming" titles. In this case it's changing $_SERVER to $_server, which would not be functional. It probably won't matter for anyone, but just in case someone comes across this thread, you must use $_SERVER.



Here's the official documentation:
http://php.net/manual/en/reserved.variables.server.php

The value of Array REQUEST_URI is /test.php
The value of Array SCRIPT_NAME is /test.php
The value of Array PHP_SELF is /test.php

Presumably the three indicated elements are not interchangeable, but I can't see the difference.

I can't remember the exact differences, but they can vary. They'll usually be the same, but if you are using mod_rewrite for 'pretty URLs' you'll get some variation here (the requested filename, and the actual file on the server), and I believe the other two might vary based on how you use include(), although I'm not certain about that.


For the record, you can test all of this another way:

print_r($_SERVER); 

Note that $_SERVER can vary slightly on different servers (and depending on your configuration or maybe even how a page loads), so it's worth checking your configuration as well as the manual.
