Remove string after last hyphen [duplicate]

Answer 1

This is a little bulky but it will work for you:

$str = 'sdfsdf-sdfsdf-abcde';
$pieces = explode("-",$str);
$count = count($pieces);

for ($x = 0; $x <= $count - 2; $x++) {
   $desired_result .= $pieces[$x].'-';
} 
$desired_result = substr($desired_result, 0, -1);

echo $desired_result;

if you have a lot of them you can use this function:

function removeLast($str){
    $pieces = explode("-",$str);
    $count = count($pieces);

    for ($x = 0; $x <= $count - 2; $x++) {
       $desired_result .= $pieces[$x].'-';
    } 
    $desired_result = substr($desired_result, 0, -1);

    return $desired_result;
}

you call it by:

$str = 'sdfsdf-sdfsdf-abcde';
$my_result = removeLast($str);
