訪問 php 文件時該功能正在運行，但是當包含 php 文件時它不起作用

Question

我確實在文件test.php創建了一個函數。 當我直接打開文件時，該功能正在運行。 但是當我將文件包含在 wordpress 標題中時，我收到以下錯誤：

Fatal error: Uncaught Error: Call to a member function getDirectories() on null in /home/vdouser/domains/mytriplef.nl/public_html/test.php:48 Stack trace: #0 /home/vdouser/domains/mytriplef.nl/public_html/test.php(227): addFolders() #1 /home/vdouser/domains/mytriplef.nl/public_html/wp-content/themes/mytriplef/header.php(3): require_once('/home/vdouser/d...') #2 /home/vdouser/domains/mytriplef.nl/public_html/wp-includes/template.php(730): require_once('/home/vdouser/d...') #3 /home/vdouser/domains/mytriplef.nl/public_html/wp-includes/template.php(676): load_template('/home/vdouser/d...', true, Array) #4 /home/vdouser/domains/mytriplef.nl/public_html/wp-includes/general-template.php(48): locate_template(Array, true, true, Array) #5 /home/vdouser/domains/mytriplef.nl/public_html/wp-content/themes/mytriplef/front-page.php(1): get_header() #6 /home/vdouser/domains/mytriplef.nl/public_html/wp-includes/template-loader.php(106): include('/home/vdouser/d...') #7 /home/vdouser/domains/mytriplef.nl/public_html/wp-blog-header.php(19) in /home/vdouser/domains/mytriplef.nl/public_html/test.php on line 48

/public_html/wp-content/themes/mytriplef/header.php代碼：

<?php

require_once("test.php");

/public_html/test.php代碼：

<?php

  die("Connection failed: " . $conn->connect_error);
}

require_once "vendor/autoload.php"; 
use MicrosoftAzure\Storage\File\FileRestProxy;

$accountName = "x";
$accountKey = "x";

$shareName = "uploadmytriplef/MyTripleF/Inkomend";

$connectionString = "DefaultEndpointsProtocol=https;AccountName=$accountName;AccountKey=$accountKey";
$fileClient = FileRestProxy::createFileService($connectionString);
$sas = 'st=2020-09-22T08%3A45%3A26Z&se=2088-07-16T08%3A45%3A00Z&sp=rl&sv=2018-03-28&sr=s&sig=ANWMpYimZlvEM4qDVuDpljy%2B4KNHT%2BC47qtvrsDlXno%3D';
$list = $fileClient->listDirectoriesAndFiles($shareName);

$azureFoldersArray = array();

function addFolders() {

    global $shareName;
    global $list;
    global $fileClient;
    global $accountName;
    global $sas;
    global $azureFoldersArray;

    // FOLDERS
    foreach($list->getDirectories() as $folders) {

        $folderName = $folders->getName();
        $shareName = "uploadmytriplef/MyTripleF/Inkomend/".$folderName."";
        $list = $fileClient->listDirectoriesAndFiles($shareName);

        // CREATE FOLDER
        $shareName = "uploadmytriplef/MyTripleF/Inkomend/$folderName";
        if (!file_exists("azure_storage/".$folderName."")) {
            mkdir("azure_storage/".$folderName."", 0777, true);
        }
        
        array_push($azureFoldersArray, $folderName);

        addFiles($folderName, $shareName);

        global $conn;

        $sql = "INSERT INTO mytriplef_folders (name) VALUES ('$folderName')";

        if ($conn->query($sql) === TRUE) {
            
        } else {
            
        }

    };

    checkFolders();

}

有人知道為什么當我將它包含在header.php時函數不起作用，但是當我直接訪問test.php文件時它起作用

謝謝！

將test.php文件放入與包含它的文件相同的目錄中，即放入[...]..../mytriplef/ ，這顯然是您的主題文件夾。 這樣你使用的文件路徑（即包括它沒有任何目錄）將是正確的。
