If the querystring contains duplicate keys in the key-value pairs, parse_str will only return the
last instance of the value. For example, in the following:
<?php
$mystr = "test1=blah&test2=bleh&test1=burp";
parse_str($mystr, $myarray);
echo $myarray['test1'];
?>
The value output will be 'burp'.
I wrote a function that takes a querystring and returns the the key-value pairs as a two-dimensional
array so each duplicate key is available:
<?php
$str = "test1=blah&test2=bleh&test1=burp";
$valsarray = parse_str_ext($str);
echo $valsarray['test1'][0];
echo $valsarray['test1'][1];
echo $valsarray['test2'][0];
function parse_str_ext($toparse) {
$returnarray = array();
$keyvaluepairs = split("&", $toparse);
foreach($keyvaluepairs as $pairval) {
$splitpair = split("=", $pairval);
if(!array_key_exists($splitpair[0], $returnarray)) $returnarray[$splitpair[0]] = array();
$returnarray[$splitpair[0]][] = $splitpair[1];
}
return $returnarray;
}
?>
Output will be:
blah
burp
bleh
