How to match a str search with an array

[sgt_wolfgang]

Hello everyone,

I'm new to the forums, and semi new to PHP in general. Sorry if I post this in the wrong place 🙁

I'm trying to create a function that does a haystack search using $_SERVER['HTTP_HOST'], and using an array that contain keywords as the needle. If anyword within the array match a word inside the HTTP_HOST, I want that word to be displayed. However I am not having success with this.

Can someone please help me and let me know what I am doing wrong?

This is a snippet of my code
// $fetched pulls an array that contains 6 keywords array("site 1", "site 2", "site 3", etc)

public function fetchSite() {
$fetched = self::\pull($site);
$sites = false;
foreach ($fetched as $sites) {
if (strpos($_SERVER['HTTP_HOST'], $fetched) !== False) {
$sites = $fetched;
}
return $sites;
}

If you can give me some direction on how to solve this issue, I would greatly appreciate it!

Thanks in advanced

Make sure that you are taking care of the case sensitivity. strpos is case sensitive search.
Also there is an issue in the code:
The "return $sites;" is at the wrong place.
According to this logic, the foreach loop will run only for the qdt iteration for $fetched and see if it found the site in the HTTP_HOST or not. Whether the match was successful or not, it'll return from the foreach loop without running the foreach for the next value of $fetched. So it should look like:

foreach ($fetched as $sites) {
if (strpos($_SERVER['HTTP_HOST'], $fetched) !== False) {
$sites = $fetched;
return $sites;
}
// return $sites; // this is a wrong place to keep to return statement.
}
