Reading all the URL parameters

[Rauldinho]

Hi, i wanted to know how i can read all the parameters coming from the URL in PHP. For example:

www.something.com?a=1&b=2&c=3

and then in a php file i have something like a cycle that gives me an output like this:

First Parameter: a is 1
Second Parameter: b is 2
Third Parameter: c is 3

Thanks for any help, hope i made myself clear!

This is how you could do it. There's probably an easier way

$keys = array();
$values = array();

foreach ($_GET as $key => $value) {
 array_push($keys, $key);
 array_push($values, $value); 
}

$variables  = sizeof($keys);

for($i=0;$i<=($variables-1);$i++) {
 $number = $i+1;
 echo "Variable $number is: $keys[$i] is $values[$i]<br />";
}

A more universal example:

foreach($_GET as $i => $k)
echo "Variable number ".($r++).": Key:$i Value:$k<br>\n"; 

Or you could just use print_r:

print_r($_GET);

while(list($key,$value) = each($_GET)){
// do whatever you want in here

This is old school stuff.

while(list($key,$value) = each($_GET)){
// do whatever you want in here
} 

Use the more efficient FOREACH proposed by ZackBloom.
