this function takes a space-deliminted string as a list of potential needles and runs it against
another string as a haystack.
the number of positive matches of needles within the haystack is returned as a rounded percentile.
<?php
function keyMatch($needles,$haystack) {
$nArray=split(" ",$needles);
$found=0;
$best=count($nArray);
for($i=0;$i<count($nArray);$i++) {
$pzn=strpos(strtoupper($haystack),strtoupper($nArray[$i]));
if ($pzn>-1) { $found++; }
}
$pct=($found*100)/$best;
return round($pct);
}
$test = keyMatch("the quick wolf","the quick brown fox jumps over the lazy
dog");
echo($test);
?>
RESULT:
67
(because "the" and "quick" were found but "wolf" was not)
