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。
