我有下面提到的表格。并獲得以下輸出。幫助我使用 foreach 循環(huán)獲得如下輸出。array('notification') = array('pos_id' => 'kiran','post_usr' => 'kumar','comment' => 'kaleti');array('project') = array('Project_name' => 'india','Proejct_lang' => 'hyderabad');這是控制器代碼。// controllerpublic function form_submit() {   $total_data = $this->input->post();   print_r($total_data);  //output :Array ( [notification|pos_id] => kiran [notification|post_usr] => kumar [notification|comment] => kaleti [project|Project_name] => india [project|Proejct_lang] => hyderabad )  foreach ( $total_data as $key => $value ) {     $arr = explode("|",$key);     echo $arr[0]."--".$arr[1]."--".$value."<br />";   }}
