Question

I know I’m probably missing something easy, but I have a foreach loop and I’m trying to modify the values of the first array, and output a new array with the modifications as the new values.

Basically I’m starting with an array:
0 => A:B
1 => B:C
2 => C:D

And I’m using explode() to strip out the :’s and second letters, so I want to be left with an array:
0 => A
1 => B
2 => C

The explode() part of my function works fine, but I only seem to get single string outputs. A, B, and C.

Sounds like you want something like this?

$initial = array('A:B', 'B:C', 'C:D');
$cleaned = array();
foreach( $initial as $data ) {
  $elements = explode(':', $data);
  $cleaned[] = $elements[0];
}
