PHP Check URL parameters against an array

Question

I'm using the following code to echo a part of a URL and my dynamic URL now looks like this.

https://example.test/test.php?name=living-room

But the condition is that, it will only echo if the name part of the URL is in my array.

$array = array('kitchen', 'bedroom', 'living room', 'dining room');
if (in_array($_GET['name'], $array))
{echo $_GET['name'];}  
else {header("HTTP/1.0 404 Not Found");}

What I'm trying to do is treat the - in URL's name part as spaces.

For example, living-room should be equal to living room in my array and it should echo the value in my array (living room) instead of (living-room).

So if the URL's value is living-room, we check the array and since living room exists in the array living room will get echoed.
In the same way as before, if the URL's value is dining-room, since dining room exists in my array, dining room will get echoed.

I'm having a hard time finding the correct logic to this.

It's fine if you're eager to learn PHP, but could you please, on Stackoverflow, before creating new contributions research your topic in existing contributions first? Your previous question follows borderline a similar pattern. There is also the PHP documentation available for studying which has the bricks you can build the logic on. — hakre

You can do a string replace while echoing the string from URL parameter. You can do something like this:

header("Content-Type: text/plain");
$name = $_GET['name'];
$name = str_replace("-"," ",$name); // Replace - with space
    
$array = ['kitchen', 'bedroom', 'living room', 'dining room'];
    
if (in_array($name, $array, true)) {
    // Found
    echo $name, "\n"; 
} else {
    // Not found
    header("HTTP/1.0 404 Not Found");
}

You can use str_replace to replace "-" (U+002D HYPHEN-MINUS) with " " (U+0020 SPACE) in your string like so:

header("Content-Type: text/plain");

$array = ['kitchen', 'bedroom', 'living room', 'dining room'];
$needle = str_replace("-", " ", $_GET['name']);
if (in_array($needle, $array, true)) {
    echo $needle, "\n";
} else { 
    header("HTTP/1.0 404 Not Found");
}
