To begin, it's far easier to use a regular expression. The regex I will
use is the following:

/(\w+)\s(4,|4$)/

And here's the PHP code I wrote up:

<?php
$string = 'arrived 2, tested 4, passenger 2, arts 4';
$regex = '/(\w+)\s(4,|4$)/';
$matches = array();

if (preg_match_all($regex, $string, $matches)) {
$actualMatches = array_shift($matches);
$string = implode(' ', $actualMatches);
}

echo "$string\n";
?>

I'm sure that there's a better way to do this, but my method appears to
work well.
