Answer 1

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$search = $_POST['search'];
$lines = file('data.txt');

foreach($lines as $line) {
if(strpos($line, $search) !== false){
echo $line;
}
}
}
I think that "foreach" is not correctly placed within the "if" statement. Try that code I give you with "foreach" inside "if"
