Answer 1

This should work for you:

<?php

    $string = "Hello World; lorem ipsum dolor";
    echo $string = substr($string, 0, strpos($string, ";"));

?>

Output:

Hello World

Answer 2

You need to split the string with ; and get first element from the returned array (it will always have at least one entry).

echo explode(';', $string, 2)[0];

explode()
