[RESOLVED] Can a user create an index for superglobal $_SERVER

jtp51

PHP 4.4.9

I understand that the indices for $_SERVER are created by the web server. However, while doing a review - I came across this statement:

$_SERVER['ORIGINAL_PHP_SELF'] = $_SERVER['PHP_SELF'];

I know there is no index labeled ORIGINAL_PHP_SELF for the $_SERVER superglobal.

Can a user create their own $_SERVER index?

I tested this with the following on the cli:

php -r '$_SERVER['ORGINAL_PHP_SELF'] = "Test"; echo($_SERVER['ORIGINAL_PHP_SELF']);'

Nothing was returned.

It will work if you fix your quoting. 😉

php -r "$_SERVER['test'] = 'test';echo $_SERVER['test'];"

Note however that such a change would only apply to the current script, so it's a bit hard to see what use this would be. If you just want a way to store something in a super-global context, it would probably make more sense to use the $GLOBALS array.

my server needs

php -r '$_SERVER['test'] = 'test';echo $_SERVER['test'];'

if i used "" i get
Parse error: syntax error, unexpected '[' in Command line code on line 1

Thanks guys...

I understand the point about just using the $_GLOBAL array, which I went with. From the example, I had to use:

php -r '$_SERVER["ORIGINAL_PHP_SELF"] = 'Hello';echo($_SERVER["ORIGINAL_PHP_SELF"]);'

This test was on Linux x86_64 RHEL.
