Check if value exists in external file array php

Question

I have this code which is to check if google exist in the external array file, it gives me the blank result but when i transferred the array into the same file or inline the list, it works. I'm using the external array file for global use.

$approveurl = file('../webfilters.php');
if(in_array('http://google.com', $approveurl)){ echo "Success";}

The external array file looks like this vergleich-webhosting.info alltemplate.org executivestudio.net — Marc Justin Rait

you want to check the html code of this sites to see if there is the string http://google.com ? — user1986815

Yes, the file() code returns the external file into array when i use the var_dump($approveurl) it will show the list into array form. — Marc Justin Rait

At a minimum you need to use the FILE_IGNORE_NEW_LINES flag, otherwise all the strings in the array will end with newline, so they won't match. — Barmar

There's no need to turn the file into an array. Read it into a string and then use strstr().

$data = file_get_contents("../webfilters.php");
if (strstr($data, "http://google.com")) {
    echo "Success";
}
