PHP-檢查目標是否可寫

Question

我正在嘗試使用php將圖像上傳到服務器上的文件夾，但出現此錯誤消息：

Warning: move_uploaded_file(): Unable to move '/Applications/XAMPP/xamppfiles/temp/phpPoVMRg' to 'userImages/Test/Test 2.jpg' in /Applications/XAMPP/xamppfiles/htdocs/TestSite/upload.php on line 16
Error uploading file - check destination is writeable.

似乎有一些阻止上傳。 我的猜測是操作系統，但是我不確定如何允許可寫性。

我將Mac與OS X優勝美地一起使用。

這也是上傳代碼：

    <?php

session_start();

// Check for errors
if($_FILES['file_upload']['error'] > 0){
    die('An error ocurred when uploading.');
}

if(!getimagesize($_FILES['file_upload']['tmp_name'])){
    die('Please ensure you are uploading an image.');
}


// Upload file
if(!move_uploaded_file($_FILES['file_upload']['tmp_name'], 'userImages/Test/' . $_FILES['file_upload']['name'])){
    die('Error uploading file - check destination is writeable.');
}

die('File uploaded successfully.');


?> 

感謝您的回答！

使用is_writable函數

if (is_writable($directory)) {
    echo 'I can write here';
} else {
    echo 'I can not write here';
}
