Assuming I have the following URL on a webpage, how I can I utilize the explode() function to give me only the ID, and not the rest of the URL that follows the ID?
file.php?id=12345&foo=bar
I can get the ID, but there's always the following "&foo=bar".
Thanks.
If you need to treat a valid URL, you can use
parse_url
to explode the URL into different part (SCHEME, HOST, PORT, USER...)
and then, use
parse_str
on the QUERY part, in order to retrieve an array containing all your parameters.
Then, you can catch what you need.
parse_url from the manual: "This function doesn't work with relative URLs."parse_str($_SERVER['QUERY_STRING']);
echo $id;
parse_str will create PHP-variables from query-string variables.
http://www.php.net/manual/en/function.parse-str.php
If it's a full URL, you can use parse_url() to get the query string part.
If it's just a fragment, you can use explode() to get it, then parse_str():
list($path, $qs) = explode('?', $url, 2);
parse_str($qs, $args);
echo $args['id'];
The 2 tells explode() to break the string into a maximum of 2 parts (before and after the ?, in this case).
$_GET['id']explode()(or something similar). I'm lifting the URL directly from the webpage using cURL.
