Get parameter from url php

I have an HTML form field $_POST["url"], having some URL strings as the value.

Example values are:

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

etc.

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

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

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:

All the parameters after ? can be accessed using $_GET array. So,

echo $_GET['email'];

will extract the emails from urls.

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=&testin=123";
$query_str = parse_url($url, PHP_URL_QUERY);
parse_str($query_str, $query_params);
print_r($query_params);

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

As mentioned in another answer, the best solution is using parse_url().

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

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

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

Also you can do this work using regex: preg_match()

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

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

preg_replace()

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

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

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

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

I a created function from Ruel's answer.

You can use this:

function get_valueFromStringUrl($url , $parameter_name)
{
    $parts = parse_url($url);
    if(isset($parts['query']))
    {
        parse_str($parts['query'], $query);
        if(isset($query[$parameter_name]))
        {
            return $query[$parameter_name];
        }
        else
        {
            return null;
        }
    }
    else
    {
        return null;
    }
}

Example:

$url = "https://example.com/test/the-page-here/1234?someurl=key&email=";
echo get_valueFromStringUrl($url , "email");

Thanks to @Ruel.

$web_url = 'http://www.writephponline.com?name=shubham&email=';
$query = parse_url($web_url, PHP_URL_QUERY);
parse_str($query, $queryArray);

echo "Name: " . $queryArray['name'];  // Result: shubham
echo "EMail: " . $queryArray['email']; // Result:

A much more secure answer that I'm surprised is not mentioned here yet:

filter_input

So in the case of the question you can use this to get an email value from the URL get parameters:

$email = filter_input( INPUT_GET, 'email', FILTER_SANITIZE_EMAIL );

For other types of variables, you would want to choose a different/appropriate filter such as FILTER_SANITIZE_STRING.

I suppose this answer does more than exactly what the question asks for - getting the raw data from the URL parameter. But this is a one-line shortcut that is the same result as this:

$email = $_GET['email'];
$email = filter_var( $email, FILTER_SANITIZE_EMAIL );

Might as well get into the habit of grabbing variables this way.

$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.

In Laravel, I'm using:

private function getValueFromString(string $string, string $key)
{
    parse_str(parse_url($string, PHP_URL_QUERY), $result);

    return isset($result[$key]) ? $result[$key] : null;
}

A dynamic function which parses string URL and gets the value of the query parameter passed in the URL:

function getParamFromUrl($url, $paramName){
  parse_str(parse_url($url, PHP_URL_QUERY), $op); // Fetch query parameters from a string and convert to an associative array
  return array_key_exists($paramName, $op) ? $op[$paramName] : "Not Found"; // Check if the key exists in this array
}

Call the function to get a result:

echo getParamFromUrl('https://google.co.in?name=james&surname=bond', 'surname'); // "bond" will be output here

How do I find the parameter of a URL?

Method 1: Using the URLSearchParams Object The URLSearchParams is an interface used to provide methods that can be used to work with an URL. The URL string is first separated to get only the parameters portion of the URL. The split() method is used on the given URL with the “?” separator.
