How to get parameters from a URL string?

Question

I have a HTML form field $_POST["url"] having some URL strings as the value. Example values are:

https://example.com/test/1234?email=[e-mail]
https://example.com/test/1234?basic=2&email=[e-mail]
https://example.com/test/1234?email=[e-mail]
https://example.com/test/1234?email=[e-mail]&testin=123
https://example.com/test/the-page-here/1234?someurl=key&email=[e-mail]

etc.

How can I get only the email parameter from these URLs/values?

Please note that I am not getting these strings from browser address bar.

Answer 1

Use $_GET['email'] for parameters in URL. Use $_POST['email'] for posted data to script. Or use _$REQUEST for both. Also, as mentioned, you can use parse_url() function that returns all parts of URL. Use a part called 'query' - there you can find your email parameter. More info: http://php.net/manual/en/function.parse-url.php

Answer 2

$uri = $_SERVER["REQUEST_URI"];
$uriArray = explode('/', $uri);
$page_url = $uriArray[1];
$page_url2 = $uriArray[2];
echo $page_url; <- see the value

This is working great for me using php

Answer 3

Use the parse_url() and parse_str() methods. parse_url() will parse a URL string into an associative array of its parts. Since you only want a single part of the URL, you can use a shortcut to return a string value with just the part you want. Next, parse_str() will create variables for each of the parameters in the query string. I don't like polluting the current context, so providing a second parameter puts all the variables into an associative array.

$url = "https://mysite.com/test/1234?email=[e-mail]&testin=123";
$query_str = parse_url($url, PHP_URL_QUERY);
parse_str($query_str, $query_params);
print_r($query_params);

//Output: Array ( [email] => [e-mail] [testin] => 123 ) 

Answer 4

you can use below code to get email address after ? in the URL

<?php
if (isset($_GET['email'])) {
    echo $_GET['email'];
}

Answer 5

You can use the parse_url() and parse_str() for that.

$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['email'];

If you want to get the $url dynamically with PHP, take a look at this question:

Answer 6

As mentioned in other answer, best solution is using

parse_url()

You need to use combination of parse_url() and parse_str().

The parse_url() parse URL and return its components that you can get query string using query key. Then you should use parse_str() that parse query string and return values into variable.

$url = "https://example.com/test/1234?basic=2&email=[e-mail]";
parse_str(parse_url($url)['query'], $params);
echo $params['email']; // [e-mail]

Also you can do this work using regex.

preg_match()

You can use preg_match() to get specific value of query string from URL.

preg_match("/&?email=([^&]+)/", $url, $matches);
echo $matches[1]; // [e-mail]

preg_replace()

Also you can use preg_replace() to do this work in one line!

$email = preg_replace("/^https?:\/\/.*\?.*email=([^&]+).*$/", "$1", $url);
// [e-mail]
