array question?

[mshen]

I have two arrays.that are array1,array2.some of the values in array1 are also in array2.

I want to create a new array.that include the values existed in array1 but not existed in array2.

Do you know which array function can do this.Thanks a lot.

for example:

array1 :1,2,3,4,5
array2:1.2.3

I want to get a new array.that include 4 and 5.

Thanks

try array_diff(). Here's an example:

$array1 = array("1", "2", "3", "4", "5");
$array2 = array("1", "2", "3");

$array3 = array_diff($array1, $array2);

foreach($array3 as $value) {
   echo $value . "<br>";
}

Well im not going to do the code for you, but it will have to work like this:

User in_array() on each value in array1 on array 2, and build an array off that, ie:

foreach($array1 as $value)
{
       if(!in_array($value, $array2))
      {
             $array3 = $value;
      }
}

But, i think this wioll only work if array2 is bigger then array1
