Comparing Arrays.

[Mad_T]

I'm trying to compare 2 arrays and report the differences between both arrays.

Doing :
print_r(array_diff($new,$old)) only shows the differences one way, so I have to run it again as print_r(array_diff($old,$new)) to see the differences the other way.

<?

$new = array (
  0=>"newALL",
  1=>"TEST,2",
  2=>"TEST,3",
  3=>"TEST,4");

$old = array (
  0=>"newA,40",
  1=>"newA,41",
  2=>"TEST,2",
  3=>"TEST,3",
  4=>"TEST,4",
  5=>"newit,2",
  6=>"newit,3");

print_r(array_diff($new,$old));
print_r(array_diff($old,$new));

?> 

is there a better way to do it ? how do I get both sets of results into one new array ? 🙂

Thanks

Something like:

$result = array_merge(array_diff($new, $old), array_diff($old, $new));
