Question

Sorry guys, not being lazy, I know others have had the same error message solved but I still couldn’t figure it out so I had to ask.

I have 2 2d arrays each with a string and a corresponding int.

I’m trying to compare the strings in the first array to the strings in the second and if they are the same, i want to add the corresponding integers together.

I am getting the error – “Cannot use a scalar value as an array” on the 7th line

for($countOne=0; $countOne<10; $countOne++)
    {
    for($countTwo=0; $countTwo<10; $countTwo++)
     {
       if($blekko_Array['url'][$countOne]==$bing_Array['url'][$countTwo])
       {
         $blekko_Array['score']['$countOne'] = $blekko_Array['score']['$countOne'] + $bing_Array['score']['$countTwo'];
        }
     }
    }

Anyone know what the problem is?

Thanks

This should do it:

foreach ($blekko_Array as &$blekko) {
    foreach ($bing_Array as $bing) {
       if($blekko['url']==$bing['url']) {
           $blekko['score'] += $bing['score'];
       }
    }
}

For one thing, your code is hardwired to look through 10 items, so if your array has less than 10 entries, you’ll get errors on the missing ones.
