php's explode array index

Using php's explode with the following code

$data="test_1, test_2, test_3";
$temp= explode(",",$data);

I get an array like this

array('0'=>'test_1', '1'=>'test_2', 2='test_3')

what I would like to have after explode 

array('1'=>'test_1', '2'=>'test_2', 3='test_3')

Lloyd Watkin's answer makes the fewest function calls to achieve the expected result. It is certainly a superior answer to ManseUK's method which uses four functions in its one-liner after the string has been exploded.

Since this question is nearly 5 years, old there should be something valuable to add if anyone dare to chime in now...

I have two things to address:

  1. The OP and Lloyd Watkins both fail to assign the correct delimiter to their explode method based on the sample string. The delimiter should be a comma followed by a space.

    Sample Input:

    $data="test_1, test_2, test_3";

  2. No one has offered a one-liner solution that matches Lloyd's two-function approach. Here that is: (Demo)

    $temp=array_slice(explode(", ",", $data"),1,null,true);

    This two-function one-liner prepends the $data string with a comma then a space before exploding it. Then array_slice ignores the first empty element, and returns from the second element (1) to the end (null) while preserving the keys (true).

    Output as desired:

    array(
    1 => 'test_1',
    2 => 'test_2',
    3 => 'test_3',
)

You couldn't do it directly, but this will do what you're after:

$temp=explode(',',',' . $data);
unset($temp[0]);
var_dump($temp);
array(3) {
  [1]=>
  string(6) "test_1"
  [2]=>
  string(7) " test_2"
  [3]=>
  string(7) " test_3"
}

it is impossible using explode. 

for($i = count($temp) - 1; $i >= 0; $i--) 
    $temp[$i + 1] = $temp[$i];
unset($temp[0]);

You could something like this :

$temp = array_combine(range(1, count($temp)), array_values($temp));

uses array_combine() to create array using your existing values (using array_values()) and range() to create a new range from 1 to the size of your array

You could use this possibly (untested)

$newArray=array_unshift($temp,' ');
unset($newArray[0]);

Array indexes start at 0. If you really wanted to have the array start with one, you could explode it, then copy it to another array with your indexes defined as starting at 1 - but why?
