Question

I have an array like

$array = Manufacturer => BMW
         Miles => 10000

and I would like to use this to create a new array with a specific name/value like this :

$array = st_selval_0_0 => Manufacturer
         st_tmdata_0_0 => BMW

         st_selval_0_1 => Miles
         st_tmdata_0_1 => 10000

As you can see the last digit must increase on each new name=>value.

Answer 1

$result = array();
$i = 0;
foreach($array as $key => $val) {
  $result['st_selval_0_'.$i] = $key;
  $result['st_tmdata_0_'.$i] = $val;
  $i++;
}

See also foreach in the manual.
