Comparing Two Arrays with PHP
Is there a way to do the following:
Compare the elements of two arrays and see if any element in one matches any element in the other (the arrays may be different lengths).
For instance:
Array 1 contains:
red
green
blue
balck
white
Array 2 contains:
pink
purple
blue
The resulting expression would show "true" since arrays 1 and 2 both have blue.
Is this possible?

Ah, perfect. That seems to be what I'm looking for! Many thanks!
print_r($ar); //this will show the matching items.
should be
print_r($a3); //this will show the matching items.

$a1 = array('red','green','blue'
$a2 = array('pink','purple','blu
$a3 = array_intersect($a1,$a2);
If (count($a3) > 0) {
echo "Has Some Items";
print_r($ar); //this will show the matching items.
} else {
echo "No matching items";
}
