Case proof variables

[lucianoes]

Dear friends,

How can I convert a variable name (rather than its value) to lowercase before it gets parsed?

In more detail: I have www.url.com/?foo=fighter . If some dope writes 'FigHTer' instead of 'fighter', no problem. My script already handles that. But what if the person, for some reason, types all the URI in caps and creates the variable 'FOO'? What if I want to make it "dope-proof" and handle even 'fOo', 'fOO' and other variants?

    Thank you,

check this:
<?php
for ( reset($HTTP_GET_VARS); list($key, $value)= each($HTTP_GET_VARS); )
{
if (strcasecmp($key, 'foo') == 0)
{
$foo = $value;
};
};
echo $foo;
?>

if you have PHP4 , you can use foreach' statment instend offor'

a break was added , to be faster
<?php
for ( reset($HTTP_GET_VARS); list($key, $value)= each($HTTP_GET_VARS); )
{
if (strcasecmp($key, 'foo') == 0)
{
$foo = $value;
break;
};
};
echo $foo;
?>

Or:

parse_str(strtolower($QUERY_STRING), $aVars);
extract($aVars);
print_r($GLOBALS);
