Question

I have an array of the type:

array(4) {[0]=> string(1) “1” [1]=> string(1) “2” [2]=> string(1) “3” [3]=> string(1) “4”}

And I need to make a multidimensional array like this:

$data = array(
   array(
      $id => '1' ,
   ),
   array(
      '$id' => '2' 
   )
   ),
   array(
      '$id' => '3' 
   )
   ),
   array(
      '$id' => '4' 
   )
);

Where $id has constant value(let’s say 6) and the value of the multidimensional array is the value from the first array.

Thanks

Answer 1

$data = array();

for($i=0;$i<count($firstArray);++$i) {
    $data[] = array('$id' => $firstArray[$i]);
}

Did you mean this?

Edit:

Sorry, I misread you question.

$data = array(); $id = '6';

for($i=0;$i<count($firstArray);++$i) {
    $data[] = array($id => $firstArray[$i]);
    // Or:
    // $data[] = array();
    // $data[$i][$id] = $firstArray[$i];
}

Edit 2:

Here is a testcode:

<?php

$firstArray = array("1", "2", "3", "4");

$data = array(); $id = '6';

for($i=0;$i<count($firstArray);++$i) {
    $data[] = array($id => $firstArray[$i]);
    // Or:
    // $data[] = array();
    // $data[$i][$id] = $firstArray[$i];
}

print_r($data);

?>

And the output:

Array
(
    [0] => Array
        (
            [6] => 1
        )

    [1] => Array
        (
            [6] => 2
        )

    [2] => Array
        (
            [6] => 3
        )

    [3] => Array
        (
            [6] => 4
        )

)
