Php method is_uploaded_file() fails without a reason!

[yord]

Hello,

I have a PHP based site running for 2 years without any problems. The
user can upload images and I run the is_uploaded_file() method to
check if the file was really uploaded via HTTP POST. During the last
week this method fails. I haven't changed anything in my code, I was
on holidays!

Were there any updates that made my code malfunction?
Do you have any other ideas on what is the problem?

PS: I know that PHP is not your responsibility but I'm stuck, so I'm
trying everything.

Thank you

Things I can think of:

- There's a problem with the temp directory where uploads are stored
- The sysadmin installed or upgraded a security filter like mod_security
- The sysadmin changed the default settings in Apache or PHP that affect
the maximum size of uploads

Hi,
I agree with this.
Also you might want to check if the safe_mode is turned on by the
admin of the hosting. To my knowledge, if the safe_mode is turned on,
then some functions (i.e. mail, upload, etc) are not applicable. I
once experienced the same thing with mail() function.
