Using preg_replace on an array

Question

I have a relatively large array of elements which I want to search for a string and replace any matches. I\'m currently trying to do this using preg_replace and

Answer 1

Your value does not sit in the array as a simple element but as a subset right? Like so?

array (
  array ('id' => 45, 'name' => 'peter', 'whatyouarelookingfor' => '5F'),
  array ('id' => 87, 'name' => 'susan', 'whatyouarelookingfor' => '8C'),
  array ('id' => 92, 'name' => 'frank', 'whatyouarelookingfor' => '9R')
)

if so:

 $value) {
  $array[$key]['whatyouarelookingfor'] =  
    preg_replace("/\d?\dIPT\.\w/", "IPT", $value['whatyouarelookingfor']);
}

Or if more elements have this, just go broader:

 $value) {
  $array[$key] =  
    preg_replace("/\d?\dIPT\.\w/", "IPT", $value);
}
