php, manipulate arrays, combine array, associative

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.

Answer 2

$newArray = array();
$i=0;

foreach($array as $k => $v)
{
  $newArray["st_selval_0_$i"] = $k;
  $newArray["st_tmdata_0_$i"] = $v;
  $i++;
}

Answer 3

$input = array('Manufacturer' => 'BMW', 'Miles' => 10000);
$output = array();

$i = 0;
foreach ($input as $key => $value) {
    $output['st_selval_0_' . $i] = $key;
    $output['st_tmdata_0_' . $i] = $value;
    $i++;
}

print_r($output);

Output:

Array
(
    [st_selval_0_0] => Manufacturer
    [st_tmdata_0_0] => BMW
    [st_selval_0_1] => Miles
    [st_tmdata_0_1] => 10000
)
