Bug #17606 File upload fails on large files
Submitted: 2002-06-05 07:09 UTC Modified: 2003-06-03 02:42 UTC

Status: Closed Package: HTTP related
PHP Version: 4.2.1 OS: RedHat 7.3
Private report: No CVE-ID:

Upload fails regardless the value of memory_limit  
	I am using the following values for post 
file uploading: 
		memory_limit = 10M 
		post_max_size = 10M 
		file_uploads = On 
		upload_max_filesize = 10M 
		allow_url_fopen = On 
	Uploading anything bigger than a pair of 
megs fails 
	I have also tried with php-4.1.2-7 but then 
I could only upload till memory_limit value, and 
the upload tmp dir is only used when the whole 
file is in memory, so I can only upload files up 
to the amount of memory y have in the system.

The first problem was solved (now memory_limit is 
used) as it was a configuration problem. 
 The second problem still stays. The upload eats 
system memory until memory_limit. If I am using a 
tmp dir why does this happen?

Yeah, this is known behaviour. PHP reads the whole uploaded file into memory before writing it to disk. Not a bug.

Well, I  have been doing more tests and it seems  
that the system memory that is being used is for  
the catching of the filesystem. I dont know if it  
is a good thing that so many memory is eaten just  
for file catching but this is an operating system  
issue and not php related bug so If everyone  
agrees I close the bug.   
Regarding last message from, 
did you double check the values for the php.ini 
file, related with post and file uploading? 
Remenber that post limit should be at least 
filesize+size of php script. 
		  memory_limit =  ?? 
                post_max_size =  ?? 
                file_uploads = On  
                upload_max_filesize = ??  
                allow_url_fopen = On
