Question

I have the following string

$url_part = 'p=link&u=shuja&sort=recent';

I want to get string start with p= and end with & in such a way,

$page = 'link'; 

and it may exist anywhere in $url_parts. Then remove the same like that

$url_part = 'u=shuja&sort=recent';

Answer 1

$url_part = 'p=link&u=shuja&sort=recent';
$params = array();
parse_str($url_part, $params);
$page = isset($params['p']) ? $params['p'] : null;
unset($params['p']);
$url_part = http_build_query($params);
