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 $value;   echo "<br/>";  } } public function Delete($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 "<br/>";  } } public function erase_char() {  $pattern="/a-zA-Z/";  for($i=0;$i<count($this->my_array)-1;$i++)  {   if(eregi($pattern, $this->my_array[$i]))   {    $this->my_array[$i]=null;   }  }  foreach ($this->my_array as $value)   {   echo $value;   echo "<br/>";  } }}

希望本文所述对大家的php程序设计有所帮助。
