[PHP] Q: array intersection problem

2001-08-14 Thread Joe Rice 

hi,

i have two arrays that i would like
to find the intersection and at
this intersection alter the value.

$invalid = array(1,3,9);
$questions = array(1,2,3,4,5,6,7,8,9);

and i would like the result to be an new array that looks
like this:

$new_questions = array(font color=red1/font,
   2,
   font color=red3/font,
   4,5,6,7,8,
   font color=red4/font);

thank you in advance,
joe

Hi,

play with array_intersect or array_diff and some other array functions.

http://www.php.net/manual/en/function.array-intersect.php (PHP 4 = 4.0.1)
http://www.php.net/manual/en/function.array-diff.php (PHP 4 = 4.0.1)
