Remove duplicates in a php loop - only addup values from unique ID # -


ive seen many posts explaining use array_unique dont think work scenario...

i have multiple results in report, if notice picture st/ot has duplicate 1.50 , 2.00 values because each sql entry has 1.50 , 2.00 each st_ot cell

at bottom totals up, $stot_total += $data["stot"];. adding total. want total of 1.50 + 2.00 (3.50). dont want add duplicates.

all ones 1.50 have same id# well, if theres way add values id#1, id#2, id#3 , on... work me...

i apologize horrible post... question regarding st/ot values ** 

foreach($dary $data){ $stot_total += $data["stot"]; }

enter image description here

a simple modification of answer @awei should trick you:

<?php $stot_bucket = array();  foreach($dary $data) {     // since don't need access values in multi-dimensional way, combine 2 keys 1 make final summing simpler     $stot_bucket[$data["id"] . $data["stot"]] = $data["stot"]; }  $stot_total = array_sum($stot_bucket); ?>
