A simple implementation method of PHP multidimensional array to one-dimensional array,

This paper introduces a simple implementation method of PHP multidimensional array to one-dimensional array. Share to everyone for your reference, as follows:

The PHP language itself does not have a function of converting a multidimensional array into a one-dimensional array, but we can write a PHP function ourselves to implement the function of turning multidimensional into one dimension.

The use of recursion, simple rough, the entire function body 9 lines of code to achieve this function, PHP code is as follows:

$multi = Array (Array (      ' wo ',      ' Shi '),    ' php '  ),  ' Cheng ',  Array (    Array (      ' Xu ',      ' yuan ',    )  ),  '! '); $multi = Arrtoone ($multi);p Rint_r ($multi), function Arrtoone ($multi) {  $arr = array ();  foreach ($multi as $key = + $val) {    if (Is_array ($val)) {      $arr = Array_merge ($arr, Arrtoone ($val));    } el SE {      $arr [] = $val;    }  }  return $arr;}

The effect after execution:

Array ([0] = wo [1] = shi [2] = + php [3] = Cheng [4] = Xu [5] = yuan [6] = =!)
