Comparing Arrays

[utahcon]

I have two arrays, one with keywords, and one with words I care about.

I need to compare the two.

The problem I am having is that my values are not exactly the same.

Example:

$array1 = thread
$array2 = 200 thread count

I want to be able to say that $array1 is in $array2 and result from that.

Can you help?

You could use strpos().

if (strpos($array2, $array1) !== false) {
    $match = true;
}

Of course, that would match strings, not arrays. You could just loop through the second array with foreach to find matches for the text in the first array.
