delete all chars when '-' found php

Having strings like

$s1 = "Elegan-71";
$s2 = "DganSD-171";
$s2 = "SD-1";

what would be the best way to delete all chars from '-' to end like

$cleans1 = "Elegan";
$cleans2 = "DganSD";
$cleans2 = "SD";

There is substr($s1, "-",4); 

substr(string $string, int $start, int[optional] $length=null);

but how to tell that it should remove all numbers and how to know numbers size as they are variable?

ststr can does it too.

$s1 = "Elegan-71";
$clean = strstr($s1, '-', true);
echo $clean;

Assuming you are cleaning each string individually, and you don't want to end up with neither an array or a list, and that each string ends up in that pattern (dash and number), this should do the trick:

$cleans1 = preg_replace('/-\d+$/', '', $s1);

list($cleans1) = explode("-",$s1,2);

This will do what you want:

<?php
    $my_string = "happy-123";
    $hyphen_position = strrpos($my_string, '-');
    $fixed_string = substr($my_string, 0, $hyphen_position);
    echo $fixed_string;
?>

$s1 = "Elegan-71";
if (strrpos($s1, '-')){
    $cleans1 = substr($s1, 0, strrpos($s1, '-'));
}else{
    $cleans1 = $s1;
}

That should do the trick.
