function to reorganise array keys?

[Perad]

I am using unset to remove a specific array value. However this is breaking my for loops as there is a gap in the keys.

 

What function can I use to relist keys from 0, 2, 3, 4 to 0,1,2,3?

you can just use:

$array = array_values($array);

 

but, instead of for, use foreach...SO much easier:

foreach($array as $value){
  echo $value;
}
