Clone array php

Php copy array

// PHP will copy the array by default.
$a = array(1,2);

$b = $a; // $b will be a different array

$c = &$a; // $c and $a will be the same array (same reference)

Clone array php

$b = $a
  
$b = array_merge(array(), $a); // reindex the array

$arr1 = ['a'=>1, 'b'=>2, 'c'=>3];
$arr2 = $arr1;

print_r($arr1);
//['b'=>2, 'c'=>3]
// ------- OR -------
$arr2 = clone $arr1;
