array_count_values() does something like this. It groups together values and tells you how many times they occur in an array...
example ------------------------ $array = array( array("foo","bar","rex"), array("foo","bar","zip"), array("foo","bar","zoo"), array("foo","bar","rex")); /* put all elements into one array */ foreach($array as $val) { $temp_array[] = $val[2];} /* count values. see php.net/array_count_values */ $count = array_count_values($temp_array); print"<pre>"; print_r($count); print"</pre>"; -------------------- this produces ... Array ( [rex] => 2 [zip] => 1 [zoo] => 1 ) >I'd like to count the number of rows in a 2 dimensional array that >have the same data in their fifth field. Is there a PHP function >that does this? Sizeof() appears to lack condition parameters... > >...Rene > >--- >René Fournier >[EMAIL PROTECTED] > > >-- >PHP General Mailing List (http://www.php.net/) >To unsubscribe, e-mail: [EMAIL PROTECTED] >For additional commands, e-mail: [EMAIL PROTECTED] >To contact the list administrators, e-mail: [EMAIL PROTECTED] -- Jim Musil --------- Multimedia Programmer Nettmedia ------------- 212-629-0004 [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
