Php function returning associate array

Question

How can I make a function return an associative array? I am getting only values of the returned array but not keys.

Answer 1

You have to set the keys yourself , If not it adds automatically an index starting from 0. 

Example

function myfunc(){
    $arr = array();
    $arr[] = 'value0';
    $arr['key1'] = 'value1';
    $arr['key2'] = 'value2';
    $arr[] = 'value3';
    return $arr;
}

Output

// you see the first and fourth value has the index 0 and 1, 
// the other those that are defined
array(4) {
  [0]=>
  string(6) "value0"
  ["key1"]=>
  string(6) "value1"
  ["key2"]=>
  string(6) "value2"
  [1]=>
  string(6) "value3"
}

I hope this helps you.
