Why use !== FALSE to check stripos in php?

Question

Here is the code I am looking at.

foreach ($header as $idx => $field) {
    if (stripos($field, \'foo\') !== false) {
        $cols[\'foo\'] = $idx;

Dunno if something like this would be easier to maintain. Depends if you do something else in those if conditions. But you can set the keys in a config file, db, pass as argument to your function, or similar.

$keys = array(
    'foo',
    'bar',
    'brr',
    'ffo',
);
foreach ($header as $idx => $field) {
    foreach ($keys as $key) {
        if (stripos($field, $key) !== false) {
            $cols[$key] = $idx;
            break;
        }
    }
}
