Splitting strings in PHP and get last part

Question

I need to split a string in PHP by \"-\" and get the last part.

So from this:

abc-123-xyz-789

I expect to get

Answer 1

This code will do that

<?php
$string = 'abc-123-xyz-789';
$output = explode("-",$string);
echo $output[count($output)-1];
?>

Answer 2

As per this post:

end((explode('-', $string)));

which won't cause E_STRICT warning in PHP 5 (PHP magic). Although the warning will be issued in PHP 7, so adding @ in front of it can be used as a workaround.

Answer 3

Since explode() returns an array, you can add square brackets directly to the end of that function, if you happen to know the position of the last array item.

$email = 'name@example.com';
$provider = explode('@', $email)[1];
echo $provider; // example.com

Or another way is list():

$email = 'name@example.com';
list($prefix, $provider) = explode('@', $email);
echo $provider; // example.com

If you don't know the position:

$path = 'one/two/three/four';
$dirs = explode('/', $path);
$last_dir = $dirs[count($dirs) - 1];
echo $last_dir; // four

Answer 4

$string = 'abc-123-xyz-789';
$exploded = explode('-', $string);
echo end($exploded);

EDIT::Finally got around to removing the E_STRICT issue

Answer 5

Just Call the following single line code:

 $expectedString = end(explode('-', $orignalString));

Answer 6

The accepted answer has a bug in it where it still eats the first character of the input string if the delimiter is not found.

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, '-') + 1);

Produces the expected result: 5

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, ';') + 1);

Produces -2-3-4-5

$str = '1-2-3-4-5';
if (($pos = strrpos($str, ';')) !== false)
    echo substr($str, $pos + 1);
else
    echo $str;

Produces the whole string as desired.
