extract $_GET variable

[bftwofreak]

I'm trying to take the variable from a url in text form. ex.:

<?php
$url = http://www.example.com/test.php?foo=bar&test=1

I'm basically looking for a function or a way to extract the variables or at least one of them. I've tried extract, but for some reason it won't work...

[dezkit]

elaborate plz

[bftwofreak]

I'm trying to find a function to specifically draw out the variables past the "?". for example the result would be:

$foo = bar
$test = 1
-----------------or--------------
$example['foo'] = bar
$example['test'] = 1

i wrote this a while ago

function get_get($url)
{
$data = substr($url, strpos($url, '?') + 1);
$data = explode('&', $data);
foreach ($data as $value) {
	$value = explode('=', $value);
	$get[($value[0])] = $value[1];
}
return $get;
}

didn't work... the output showed as just "$" (no quotes)

[ratcateme]

$url = "http://www.example.com/test.php?foo=bar&test=1";
function get_get($url)
{
$data = substr($url, strpos($url, '?') + 1);
$data = explode('&', $data);
foreach ($data as $value) {
	$value = explode('=', $value);
	$get[($value[0])] = $value[1];
}
return $get;
}
print_r(get_get($url));

outputs

Array
(
    [foo] => bar
    [test] => 1
)

ha thank's for the clarification!

[Zane]

you know PHP has a built in function that does all that already

http://php.net/parse_url

 

you might have to explode the args key when it runs and then use foreach like the above code does....but it would be WAY less lines

 

[ratcateme]

mean i will have to remember that

Or if you want variables instead of the array:

<?php

$data = substr($url, strpos($url, '?') + 1);
$data = explode('&', $data);
foreach ($data as $_value) {
     $_value = explode('=', $_value);
     ${$_value[0]} = $_value[1];
}

echo $foo . " " . $test;
?>

 

That script won't work if _value is a name for the GET field. (The one before the = sign.)
