PHP找不到tmp目录 [英] PHP Can't find tmp directory
问题描述
我有,在tmp目录下创建文件,如 TMPFILE()
和的tempnam()
。他们似乎都未能写入TMP和返回false。 upload_tmp_dir
在PHP INI和文件上传设置正常工作。
I am having problems with functions that create files in the tmp directory such as tmpfile()
and tempnam()
. They all seem to fail to write to tmp and return false. upload_tmp_dir
is set in php ini and file uploads work fine.
在调试这个错误我发现, sys_get_temp_dir()
获取可惜这不是我的PHP版本(5.1.6)支持的tmp目录的位置。我也看到,使用下面的方法替换 sys_get_temp_dir的功能()
:
When debugging this error I found that sys_get_temp_dir()
gets the location of the tmp directory unfortunately it's not supported in my PHP version (5.1.6). I also saw that using the following method replaces the functionality of sys_get_temp_dir()
:
if ( !function_exists('sys_get_temp_dir')) {
function sys_get_temp_dir() {
if (!empty($_ENV['TMP'])) { return realpath($_ENV['TMP']); }
if (!empty($_ENV['TMPDIR'])) { return realpath( $_ENV['TMPDIR']); }
if (!empty($_ENV['TEMP'])) { return realpath( $_ENV['TEMP']); }
$tempfile=tempnam(__FILE__,'');
if (file_exists($tempfile)) {
unlink($tempfile);
return realpath(dirname($tempfile));
}
return null;
}
}
但是,到$ _ENV阵列中的tmp目录和的tempnam()
没有提及正如我前面提到失败。
But there is no reference to a tmp directory in the $_ENV array and tempnam()
fails as I mentioned before.
另外的open_basedir没有设置,我听说可能会导致类似的问题。
Also open_basedir is not set which I've heard can cause similar problems
我怎样才能找出的tmp目录是否它甚至还成立?结果
这是一个Apache服务器的配置问题还是PHP的?
How can I find out where the tmp directory is or whether it is even set?
Is this a apache server configuration issue or a PHP one?
感谢您的帮助。
推荐答案
TMP,TEMP(也许TMPDIR)是在Windows上才有效,通常指向 C:\\ WINDOWS \\ TEMP
。在Linux默认临时位置是 / tmp目录
。要解决这个(与作品的tempnam()
功能),你可以在你的网站空间中某个位置创建一个临时文件夹,指定适当的访问权限,并通过这个作为第一个参数上面的函数
TMP, TEMP (and maybe TMPDIR) are valid on Windows only and usually pointing to C:\Windows\TEMP
. On Linux default temp location is /tmp
. To workaround this (works with tempnam()
function) you can create a temp folder somewhere within your website space, specify appropriate access permissions and pass this as first parameter to the above function.
不是一个很好的解决方案,但有总比没有好。
Not a great solution but better than nothing.
