如何在文件上传 (PHP) 时分配 chmod 值 0777？

Question

我的系统具有一个对话区域，可以写入 .txt 文件并从中提取内容。显然，我可以通过 FTP 客户端设置权限，但我希望将可写功能应用于通过我的系统在 PHP 中上传的所有文件。我要补充一点，安全不是问题。

    <?php

$adminID = $_GET['adminID'];

$name = stripslashes(trim($_POST['name']));
$area = stripslashes(trim($_POST['area']));

mysql_query("INSERT INTO chat_rooms (id, name, area, adminID) VALUES ('', '$name', '$area', '$adminID')");

$image = ($_FILES['image_url']['name']);
$empty = '';


if ($image == $empty)

{
    echo 'NO IMAGE';


}else
{

 $target = "room/test/"; 
 $target = $target .basename($_FILES['image_url']['name']); 
 $target2 = basename($_FILES['image_url']['name']); 



 $image_url = ($_FILES['image_url']['name']);
 $adminarea = 'admin-index.php'; 


mysql_query("UPDATE chat_rooms set file='$image_url' WHERE name = '$name'");



 if(move_uploaded_file($_FILES['image_url']['tmp_name'], $target))
 {

 echo "";
 echo "Your room has been created using the file " . basename( $_FILES['image_url']['name']) ." <br /> <br /> Click <a href=".$adminarea."> here </a> to return to the admin area"; 
 } 
 else { 

 echo "Sorry, there was a problem uploading your file."; 
 } 


}
?>

我对我的代码的布局和一般语法表示歉意

Answer 1

只需在文件上传后调用 chmod('thefile.txt', 0777) 即可。

Answer 2

chmod：

chmod('/path/to/file.txt', 0777);
