in_array not working

[c_pattle]

I have a section in one of my scripts that checks for a value in array and the value doesn't exist in the array then it add it.  This works fine for single array but not for mulit-dimensional arrays.  Has anyone had a similar problem and knows a good solution?

 

if(in_array($words[$i], $searchWords)){
    //Do nothing
}else{
    $searchWords[] = $words[$i];
}

Have you checked if $words[$i] has the value you expect? Do you have any white-space as part of the data in the $words array that would prevent a comparison from working? Are the letter cases the same?

 

If $words is already an array, you can just use array_diff to find the words that are not already in the second array, then to add them to the second array, just use array_merge. There's no need to loop.

in_array is not recursive, you have to write your own recursive version.  Show us what $searchWords looks like.
