本文实例讲述了PHP实现C#山寨ArrayList的方法。分享给大家供大家参考。具体如下:

class ArrayList
{
 public $length;
 public $name;
 public $my_array;
 function __construct()
 {
  $this->my_array=Array();
 }
 public function Add($element)
 {
  array_push($this->my_array, $element);
 }
 public function get_Length()
 {
  $this->length=count($this->my_array);
  return $this->length;
 }
 public function get_Element($key)
 {
  if(array_key_exists($key, $this->my_array))
  {
   echo $this->my_array[$key];
  }
  else
  {
   echo "没有这个元素";
  }
 }
 public function list_array()
 {
  foreach ($this->my_array as $value) 
  {
   echo $value;
   echo "
"; } } public function Delete($key) { if(array_key_exists($key, $this->my_array)) { $this->my_array[$key]=null; } else { echo "没有这个元素"; } } public function erase_number() { $pattern="/[0-9]/"; foreach ($this->my_array as $value) { if(eregi($pattern, $value)) { $value=null; } } foreach ($this->my_array as $value) { echo $value; echo "
"; } } public function erase_char() { $pattern='/a-zA-Z/'; for($i=0;$imy_array)-1;$i++) { if(eregi($pattern, $this->my_array[$i])) { $this->my_array[$i]=null; } } foreach ($this->my_array as $value) { echo $value; echo "
"; } } }

希望本文所述对大家的php程序设计有所帮助。
