I know I'm going to forget this so I'm making a note of it here.

If you have two associative arrays...

PHP Code:

$test1['fruit'] = "banana";
$test1['veg'] = "cabbage";

$test2['fruit'] = "banana";
$test2['veg'] = "lettuce"; 


... and want to merge them, the array before the plus operator overwrites the one after it:

PHP Code:

print_r($test1 + $test2); 
print_r($test2 + $test1); 


Results in:

Array ( [fruit] => banana [veg] => cabbage )
Array ( [fruit] => banana [veg] => lettuce )

Must remember... must remember...
