PHP - 获取$ _GET字符串的一部分

Question

I currently have this:

$thispage = $_SERVER['QUERY_STRING'];

if($thispage == "i=f" || $thispage == "i=f&p=t" ) echo "active";

Although, the "i=f&p=t" is not correct, as the page looks like this:

i=f&p=t&cid=71&id=161

My question is, how can I do so if just the first part of the $_GET string is correct (in this example "i=f&p=t) then it will match $thispage. I don't want it to check for & $_GETs

I want $thispage to work with other pages than just the example above. I only want to check the first part of the string. Not what comes after &

Answer 1

I'd go for parse_str function:

parse_str($_SERVER['QUERY_STRING'], $thispage);

if ( $thispage['i'] === 'f' OR ($thispage['i'] === 'f' AND $thispage['p'] === 't') ) {
    echo 'active';
}

Update:

I don't want it to check for & $_GETs

I don't know why you don't want to use $_GET if it's the Query String that you're working on that now, but you can do the following as well, which makes more sense:

if ( $_GET['i'] === 'f' OR ($_GET['i'] === 'f' AND $_GET['p'] === 't') ) {
    echo 'active';
}
