Users can input URLs using a HTML form on my website, so they might enter something like this: http://www.example.com?test=123&random=abc, it can be anything. I need to extract the value of a certain query parameter, in this case 'test' (the value 123). Is there a way to do this?

To get the query string from a URL in php, you can use $_GET super global to get specific key value pairs or $_SERVER super global to get the entire string. A query string is a part of a URL that assigns values to specified parameters.
QueryParam annotation in the method parameter arguments. The following example (from the sparklines sample application) demonstrates using @QueryParam to extract query parameters from the Query component of the request URL.
A query string is a term for adding/passing data in the URL. It is not language specific.
PHP $_GET is a PHP super global variable which is used to collect form data after submitting an HTML form with method="get". $_GET can also collect data sent in the URL. When a user clicks on the link "Test $GET", the parameters "subject" and "web" are sent to "test_get.
- GeeksforGeeks How to get parameters from a URL string in PHP? The parameters from a URL string can be retrieved in PHP using parse_url () and parse_str () functions. Note: Page URL and the parameters are separated by the ? character. parse_url () Function: The parse_url () function is used to return the components of a URL by parsing it.
The PHP way to do it is using the function parse_url, which parses a URL and return its components. Including the query string. $url = 'www.mysite.com/category/subcategory?myqueryhash'; echo parse_url ($url, PHP_URL_QUERY); # output "myqueryhash" The function parse_str () automatically reads all query parameters into an array.
With the help of the parse_str () function, you can parse query strings into variables. The syntax of this function is like so: Now, let’s see examples of how to use these two functions for getting the parameters from the URL string.
A query string is a part of a URL that assigns values to specified parameters. When building web pages, query strings help us pass and access information to be used on our web pages. When working in php, the ability to easily access and work with query strings is important.
You can use parse_url and parse_str like this:
$query = parse_url('http://www.example.com?test=123&random=abc', PHP_URL_QUERY); parse_str($query, $params); $test = $params['test']; parse_url allows to split an URL in different parts (scheme, host, path, query, etc); here we use it to get only the query (test=123&random=abc). Then we can parse the query with parse_str.

I needed to check an url that was relative for our system so I couldn't use parse_str. For anyone who needs it:
$urlParts = null; preg_match_all("~[\?&]([^&]+)=([^&]+)~", $url, $urlParts); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
