You could for example explode it and array_count_values it.

<?php
$string = "this time, I eat this";
$string = preg_replace("/[^a-z1-0 ]/i",'',$string);
$a = explode(' ',$string);
$words = array();
while ($word = each($a)) {
if (!array_key_exists($word,$words)) $words[$word] = 1;
else $words[$word]++;
}
foreach ($words as $word => $count) {
echo "$word appears $count time".(($count > 1)? 's':'')."\n<br>\n";
}
?>
