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.
