Simple example code for PHP to recursively print all elements in an array

<?php
/**
* 递归打印数组中所有元素
* edit bbs.it-home.org
*/
    //@patten:为打印前的字符串，不同的层次会增加该串打印的次数
    //@array：为要打印的数组
    function print_array($patten, $array){
      $retstr;
      foreach($array as $value){
        if( is_array($value) ){
          $patten = $patten.$patten;
          print_array($patten, $value);
        } else {
          echo "<p>".$patten."[".key($array)."]".": ".$value." <br/> ". "</p>";
        }
      next($array);
      }
    }
?>

print_array("-", $array);
