Querystring loop... Simple but not getting it.

[kaustic]

I have an SWF passing a querystring to a PHP file.

 

ex: page.php?var=foo&var=bar&var1=3

 

The querystring contains multiple values with the same key (var in the example above).

 

How can I loop through the "var" key and get its values? I've tried over and over again with no luck. Basically, using the example above, I'd like to loop through var and echo all values (foo and bar).

 

I realize this is probably simple but I'm simply not able to get a loop to work with the querystring. Any help would be appreciated.

<?php
$qs = $_SERVER['QUERY_STRING'];
$q_array = explode('&', $qs);
foreach($q_array as $pair){
$p_array = explode('=', $pair);
echo $p_array[0] . ' ' .$p_array[1] . '<br />';
}
?>

 

Best,

Patrick, that worked. I added an if statement to pull just the var values. Is there a more efficient manner if all I want to extract is the var values?

 

Thanks for the help. I'd tried something similar but never got it to work. Think I've been up too long.

Why are you getting data like this: page.php?var=foo&var=bar&var1=3 instead of like this: page.php?var[]=foo&var[]=bar&var1=3 ?  The latter affords you the ability to access var through the $_GET array as an array ala:

 

<?php
print_r($_GET);
// prints: Array ( [var] => Array ( [0] => foo [1] => bar ) [var1] => 3 )
?>

 

Best,

Patrick, I don't have access to the original FLA. So, I have to deal with how the data is being sent.... No choice in the matter.

I see.  Unfortunately there's not going to be a really elegant solution to the problem, since you're dealing with data that is technically malformed.  Parsing the query string manually (like the code I originally posted) is probably your best bet.
