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：
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 $value;
echo "
"; } } }
"; } } public function Delete($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;$i
"; } } }
希望本文所述对大家的PHP程序设计有所帮助。
