Comparing 2 arrays and modifying 1

Ok, assume that I have 2 arrays.

$myArray = ('1', '2', '3', '4', '5', '6', '7', '8', '9', '10');

$badNumbers = ('3', '6', '10')

What I want to do is开发者_C百科 compare $myArrays with $badNumbers, then modify $myArrays to remove anything found in the $badNumbers.

So after some code, the end result would be:

$myArray = ('1', '2', '4', '5', 7', '8', '9');

$badNumbers = ('3', '6', '10')

Is there anyway to do this? I've of some things, but nothing seems to work. The comparing part alone I already have some problems.

EDIT: I'm fine with a third array too. Something along the line of for each value, if it doesn't appear in the second array, array_push to the new array. But I'm still not so sure on how to do this.

You can use array_diff to get the result.

$myArray= array('1','2','3','4','5','6','7','8','9','0'); 
$badNumbers= array('3','6','0');
$available = array_diff($myArray, $badNumbers);

print_r($available);

echo '<br /><br />' . implode(', ', $available); 

Hope this helps.

$result = array_diff($myArray, $badNumbers);
echo count($result) ? 'there were differences' : 'there werent';

I suppose, array_diff() function does what you want.

What does "count" do? Is "echo" like "print"?

echo count($result) ? 'there were differences' : 'there werent';
