Count occurrences of target in array -- how?!

You don't want to just loop through the array and do a preg_match or strpos and add to a counter? It may not be as elegant as one single function but it'll do the job.

$counter = 0;
for($i=0; $count = count($array); $i<=$count; $i++):
     if($string == $array[$i]) $counter++;
endfor;

$i = 0;
foreach($arr as $val) {
    $string == $val ? $i++ : null;
}
echo $i;

and to address this:

we can write shorter than that in PHP

foreach($arr as $val) {$string == $val ? $coutner++ : null;}

i'm surprised you Ruby boys have to actually call element.value when dealing with arrays however it's nice to just use the .size but i assume somewhere in the language framework it actually does iterate through the array.

seriously? you post in the PHP forum giving a non-php example and you're telling me that I'm the one trying to 1-up?

my point was not that it was shorter than what you provided. Anyone can shorten variables to one character variable names. That was why i made the comment about having to write out element.value if you were posting a "shorter" example. The point was that it could be re-written as a 1 line expression... And after all this... I still have no idea why you posted your example in this forum other than to stir some php/rails debate. And really... i figured we were past all that around here.

Anyway, the array_map function might be PHP's equivalent of Ruby's #collect.

no worries I was probably ribbing you a bit too much back too apologies to you as well.
