";  }} Public Function Delete ($key) {if (Array_key_exists ($key, $this->my_array)) {$this->my_array[$key]=null;  } else {echo "does not have this element";  }} Public Function Erase_number () {$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
 
  
   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 "
