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。
