array question

[Stormkid]

Hi Group I'm trying to figure out a way that I can take two (two
dimensional) arrays and avShed and shed, and subtract the matching elements
in shed from avShed I've pasted the arrays blow from a print_r cmd any
suggestions would be great. Thanks much Todd
//avShed array

UNTESTED:

foreach($shed as $arr) {
for($i=0;$i<cou nt($avShed);++$ i) {
if ($arr[1] == $avShed[$i][1] && $arr[0] == $avShed[$i][0]) {
array_splice($a vShed, $i, 1);
$i--; //you may or may not need this
// continue 2; //<-- Uncomment if you only want 1st instance removed
}
}
}

I think this'll work. The $i-- is there in case you have 2 exact duplicates
back-to-back.
Looking back, I'm guessing there's a less cpu-intensive way to do this.

I'd change those arrays of arrays into arrays of strings and then apply
array_intersect () to them

something like this (UNTESTED):

<?php
$new1 = array();
foreach ($avShed as $arr) $new1[] = $arr[0] . '@@' . $arr[1];
// or is this $arr['dayOfWeek'] and $arr['timeInt'] ???

$new2 = array();
foreach ($shed as $arr) $new2[] = $arr[0] . '@@' . $arr[1];


$diff = array_intersect ($new1, $new2);
?>
