在同一页面上按ID包含文件

有办法做到这一点吗?

包括文件:

<?php
$_GET["id"];
case "fruits": include 'fruits.php';
?>

fruits.php:

<?php
$id = 'fruits';
echo 'hello fruits';
?>

我想按照包含文件中指定的ID包含文件。 谢谢你的帮助。

您的代码非常不完整,但这是尝试解决您的问题。

或者,如果你有一长串可能的文件,我建议如下:

<?php
// Get the ID parameter and change it to a standard form
// (Standard form is all lower case with no leading or trailing spaces)
$FileId = strtolower(trim($_GET['id']));

// Check the File ID and load up the relevant file
switch( $FileId ){
    case 'fruits':
        require('fruits.php');
        break;
    case 'something_else':
        require('something_else.php');
        break;
    /* ... your other test cases... */
    default:
        // Unknown file requested
        echo 'An error has occurred. An unknown file was requested.';
}
?>

包含大量案例的切换语句可能会变长,并且会降低可读性。因此,第二个解决方案使用数组,<?php // Get the ID parameter and change it to a standard form // (Standard form is all lower case with no leading or trailing spaces) $FileId = strtolower(trim($_GET['id'])); // Array of possible options: $FileOptions = array('fruits', 'something_else', 'file1', 'file2' /* ... etc... */); // Check if FileId is valid if(in_array($FileId, $FileOptions, true)){ // FileId is a valid option $FullFilename = $FileId . '.php'; require($FullFilename); }else{ // Invalid file option echo 'An error has occurred. An unknown file was requested.'; } ?> 函数减少代码长度。这也使您可以轻松查看/管理允许的文件。
