具有随机名称的文件夹并使用 PHP 将文件保存到其中
因此，我正在尝试创建一个 PHP 脚本，客户端可以在其中创建一个具有 10 位随机字母和数字名称的文件夹，然后将他们当前正在处理的文档保存到该文件夹中。它就像一个 JSfiddle，您可以在其中保存当前正在处理的内容，并且它会创建一个随机文件夹。我的问题是它不会创建我的目录，这个想法是正确的，它应该可以工作。但是，PHP 不保存错误日志，因此我无法识别问题。这是我到目前为止所得到的。
PHP
save_functions.php
<?php
function genRandomString() {
$length = 10;
$characters = "0123456789abcdefghijklmnopqrstuvwxyz";
$string = '';
for ($p = 0; $p < $length; $p++) {
$string .= $characters[mt_rand(0, strlen($characters))];
}
return $string;
}
<?php
function createFolder() {
$folderName = genRandomString(); //Make a random name for the folder
$goTo = '../$folderName';//Path to folder
while(is_dir($goTo)==true){ //Check if a folder with that name exists
$folderName = genRandomString();
$goTo = '../$folderName';
}
mkdir($goTo,7777); //Make a directory with that name at $goTo
return $goTo; //Return the path to the folder
}
?>
create_files.php
<?php
include('save_functions.php');//Include those functions
$doc = $_POST['doc'];//Get contents of the file
$folder = createFolder();//Make the folder with that random name
$docName = '$folder/style.css';//Create the css file
$dh = fopen($docName, 'w+') or die("can't open file");//Open or create the file
fwrite($dh, $doc);//Overwrite contents of the file
fclose($dh);//Close handler
?>
So I am creating trying to create a PHP script where the client can create a folder with a 10 digit name of random letters and numbers, and than save the document they are currently working on into that folder. Its like a JSfiddle where you can save what you are currently working on and it makes a random folder. My issue is that it wont create my directory, and the idea is correct, and it should work. However, PHP isn't saving an Error Log so I cannot identify the issue. Here's what I got so far.
PHP
save_functions.php
<?php
function genRandomString() {
$length = 10;
$characters = "0123456789abcdefghijklmnopqrstuvwxyz";
$string = '';
for ($p = 0; $p < $length; $p++) {
$string .= $characters[mt_rand(0, strlen($characters))];
}
return $string;
}
<?php
function createFolder() {
$folderName = genRandomString(); //Make a random name for the folder
$goTo = '../$folderName';//Path to folder
while(is_dir($goTo)==true){ //Check if a folder with that name exists
$folderName = genRandomString();
$goTo = '../$folderName';
}
mkdir($goTo,7777); //Make a directory with that name at $goTo
return $goTo; //Return the path to the folder
}
?>
create_files.php
<?php
include('save_functions.php');//Include those functions
$doc = $_POST['doc'];//Get contents of the file
$folder = createFolder();//Make the folder with that random name
$docName = '$folder/style.css';//Create the css file
$dh = fopen($docName, 'w+') or die("can't open file");//Open or create the file
fwrite($dh, $doc);//Overwrite contents of the file
fclose($dh);//Close handler
?>

对
mkdir($goTo,7777)的调用有错误的模式，这通常是八进制，而不是十进制或十六进制。 7777 是八进制的 017141，因此尝试设置不存在的位。尝试通常的0777。但为什么在你的情况下不直接使用
tempnam()或tmpfile()呢？The call to
mkdir($goTo,7777)has wrong mode, this is usually octal and not decimal or hex. 7777 is 017141 in octal and thus tries to set non-existent bits. Try the usual0777.But why don't you just use
tempnam()ortmpfile()in your case?
