full house with substr_count()

[snarkie]

i've got a string that looks something like this:

$string = " 3_spades 3_hearts 10_diamonds 3_diamonds 10_clubs"

i then use this to see if any of the numbers in the string match:

for ($i = 2; $i <= 14; $i++) {
   if (substr_count($string, " $i") == 3 {
      print "there are three ".$i."'s in your hand.";
      break;
   }
}

(the spaces are in the string and before the $i to make sure 13 isn't a match for 3, etc. 🙂)

so when $i hits 3, it shows 3 matches. however, now i want it to check if the other 2 numbers match each other and print "full house" if they match.

anyone have any suggestions on how to do this? i've tried a few things and nothing seems to be working.

thanks in advance!

How about

<?php
	$hand = "3_hearts 10_spades 3_diamonds 10_diamonds 3_clubs"; // no leading space
	$cards = array ();
	$handarray = explode(" ",$hand);
	for ($c=0;$c<5;$c++) {
		$pos = strpos($handarray[$c],"_");
		$cards[substr($handarray[$c],0,$pos)]++;
	}
	/* check out the results */
	foreach($cards as $num => $count) {
		echo "$num count = $count<br>";
	}


?>
