通過函數調用進行編輯PHP

Question

我在functions.php中的php頁面中封裝了函數，爲了訪問這些頁面，我在URL中放入了一個動作和一個值。我還有一個function_calls.php，它請求動作及其值，並將其傳遞給調用相應函數的開關盒。我遇到的問題是，我想要編輯一個字段。我沒有合適的情況下（開關），我想看起來像admin.php?action=edit?id=some_id。

function_calls.php

<?php 
    require_once "functions.php"; 


    if (isset($_REQUEST['action'])) { 
    $option = $_REQUEST['action']; 

    echo $option; 

    switch ($option) { 
     case "complaints": 
      complaint(); 
      break; 
     case "users": 
      users(); 
      break; 
     case "officers": 
      officers(); 
      break; 
     case "register_officer": 
      register_officer(); 
      break; 
     case "register_student": 
      register_student(); 
      break; 
     case "add_event": 
      add_event(); 
      break; 

     default: 
      complaint(); 
      break; 
    } 
} else { 
    echo '<div class="jumbotron"> 
    <h1>Welcome To The Administration Panel </h1> 
    <p>You can manage accounts and view the complaints here.</p> 

</div>'; 
} 

的functions.php

<?php 

include_once "include/db_connect.php"; 

function register_student() 
{ 
    ?>

Answer 1

這將是比你多一點優雅的解決方案：

<?php 

require_once 'functions.php'; 

if (isset($_GET['action'])) { 
    $option = $_GET['action']; 

    echo $option; 

    if(in_array($option, get_defined_functions()['user']) === true) { 
     call_user_func($option); 
    } else { 
     complaint(); 
    } 
} else { 
    echo '<div class="jumbotron"> 
    <h1>Welcome To The Administration Panel </h1> 
    <p>You can manage accounts and view the complaints here.</p> 
    </div>'; 
} 

，那麼你可以定義一個函數edit()這將被call_user_func自動調用，而不會改變每次添加一個新功能時，都會輸入switch。
