"; } } 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 "
"; } } }
