I'm trying to write a file to my /tmp directory (on an apache server) with the php fopen function, but it fails:
<?php
$handle = fopen("/tmp/test.txt", "x");
if ($handle)
echo "Success!";
else
print_r(error_get_last());
This returns the error message:
failed to open stream: No such file or directory.
The /tmp
directory has permissions set to drwxrwxrwt
and I can see that the web user is writing other files to it. Mysteriously, if I point the script to another folder with permissions 777
, it returns success. But my open_basedir
has no value. I have safe_mode=on
and allow_url_fopen=off
, but I don't think that should explain it?
This is PHP 5.3.10 on Apache Httpd 2.0.
I had exactly the same problem. PHP reported no problem with opening file in /tmp/myoutputfile
, but no file was in that path. Then I did
find / -name "myoutputfile"
and found it in /tmp/systemd-…/myoutputfile
.
I've found this article on Google.
So, in my case, it was a Systemd and Apache Httpd combination. I hope this will help to someone.
