php - 如何使用 CodeIgniter 检索 HTTP $_GET 值

Question

我坚持在 CodeIgniter 中使用 $_GET 变量，有人可以帮助我吗？

Answer 1

CodeIgniter comes with three helper functions that let you fetch POST, COOKIE or SERVER items. The main advantage of using the provided functions rather than fetching an item directly ($_POST['something']) is that the functions will check to see if the item is set and return false (boolean) if not. This lets you conveniently use data without having to test whether an item exists first. In other words, normally you might do something like this:

if (!isset($_GET['something'])){
    $something = FALSE; 
} else {
    $something = $_GET['something']; 
} 

With CodeIgniter's built in functions you can simply do this:

$something = $this->input->get('something');
