How to determine whether the URL is containing argument(s)? - php

Question

I have two kind of URLs:
First:
localhost/search?q=arg1&s=arg2
Second:
localhost/search/arg1/arg2
Note: Sometimes arguments are containing ?. Like this:
localhost/search/ar?g1/arg2 // this is belong to second kind
Well, How can I detect ths URL is which kind?
Here is my code:
$FirstKind = strpos($_SERVER['REQUEST_URI'], '?') ? true : false;
But the above code returns true for the URL if one of arguments be containing ? (as you see in the Note above).

Answer 1

You can use parse_url for this:
$parsed = parse_url ( 'YourURL' );
The GET ‘arguments’ are now in $parsed['query']
See more about parse_url()

Answer 2

Here's a possible implementation:
<?php
function getArg($arg, $url) {
$result = '';
$urlData = explode('&', parse_url($url)['query']);
foreach ($urlData as $urlPair) {
if (strpos($urlPair, '=') !== false) {
list($k, $v) = explode('=', $urlPair);
if (trim($k) == $arg) {
$result = trim($v);
break;
}
}
}
if (empty($result)) {
$urlParts = explode('/', $url);
for ($i = 0; $i < sizeof($urlParts); $i++) {
if (trim($urlParts[$i]) == trim($arg)) {
if (isset($urlParts[$i+1])) {
$result = $urlParts[$i+1];
break;
}
}
}
}
return $result;
}
Usage:
$url1 = 'localhost/search?q=arg1&s=arg2';
$url2 = 'localhost/search/ar?g1/arg2';
echo "<pre>";
var_dump(getArg('q', $url1));
var_dump(getArg('ar?g1', $url2));
echo "<pre>";
Outputs:
string(4) "arg1"
string(4) "arg2"
