array_map

Synopsis

array array_map(mixed callback, array array1[, ... array arrayN])

Creates an array by applying the callback function referenced in the first parameter to the remaining parameters; the callback function should take as parameters a number of values equal to the number of arrays passed into array_map( ). For example:

function multiply($inOne, $inTwo) {
  return $inOne * $inTwo;
}
  
$first = (1, 2, 3, 4);
$second = (10, 9, 8, 7);
  
$array = array_map("multiply", $first, $second); // contains (10, 18, 24, 28)
