I am having some problems while uploading a file to a MySQL database
relating to file sizes. I have created a script which successfully
uploads most files to the database, however anything roughly over 1MB in
size seems to return a PHP error. I am not trying to upload anything
larger than 15MB. The error I am getting is as follows:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to
allocate 8439363 bytes) in C:\Program Files\Apache Software
Foundation\Apache2.2\htdocs\_dev\mraintranet\settings\common.php on line
78 (memory_limit = 64M)
I have done a fair bit of reading on the google-net and found that this
is a very common problem. So I started changing the configuration of the
php.ini file to try and resolve it the same way others have. Currently I
have the memory_limit set to 64M, which is significantly more than the
8M or 12M that is set by default in the php.ini file. When I bump it up
to say 128M or 256M I get the same error with different
exhausted/allocated sizes. I have tried putting this up to 512M. Example:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 7311167 bytes) in C:\Program Files\Apache Software
Foundation\Apache2.2\htdocs\_dev\mraintranet\settings\common.php on line
77 (memory_limit = 128M)
That is uploading the exact same file (which is approximately 3.5MB). I
don't understand why the 'tried to allocate' size is different. I also
don't understand why the error is occurring on different lines. I have
changed post_max_size to 20M. I upgraded to PHP 5.2.1 after first
noticing the problem and reading that this version of PHP had a lot of
memory bug fixes in it. I am using the following software:
Windows 2000 (SP4)
PHP 5.2.1
Apache 2.2.4
MySQL 5.0.27
If anyone has any ideas on how to solve this then the help is greatly
appreciated.
Show us your script. Chances are that you have a bug that is causing
lots of memory to be allocated.
Incidentally, the "tried to allocate n bytes" message indicates how much
it was trying to allocate when it ran out. If you change the
memory_limit then I'm not surprised that this value changes.
