indexOf and lastIndexOf in PHP?

Question

In Java, we can use indexOf and lastIndexOf. Since those functions don\'t exist in PHP, what would be the PHP equivalent of this Java code?

Answer 1

This is the best way to do it, very simple.

$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');

echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;
