I read somewhere that the upload limit for php is about 2MBs. Does this still apply if I am asking a user to upload a file to the server to scan through and convert to a string? If so how do I get around this?
The application for this is a scanner type deal where users would be able to upload a code file, and this php application would scan through the code and look for certain comments to document and write to a documentation file.
The upload limits are configured in the php.ini file, see this: http://www.radinks.com/upload/config.php
Yes it would apply to any file that is being uploaded by the user, regardless of what your server side app does with it. :)
The upload limit can be changed by modifying the settings in php.ini file.
Yes it would (assuming it's a POST). You get around it by changing your php config.
PHP has two limits that apply in this case. Both are ini options: upload_max_filesize and post_max_size
I believe the upload_max_filesize defaults to 2 MB. (The post_max_size setting has to be larger than upload_max_filesize).

I am playing with plupload 2.1.3 and can't get it to complete an upload using their custom example. I get a 103, unable to move uploaded file. If I look in the upload directory I see the file I tried to upload listed as test.png.part. My php.ini lists /tmp as my upload_tmp_dir.
From this I gather that the permissions are correct (I even set everything to 777 temporarily -- go difference).
This is a fairly newly configured server so it may not be related to plupload.
You have to check your PHP configurations on php.ini file.
If your upload is constantly being interrupted you either need to increase the maximum upload size or the time before your PHP script times out. Check this variables:
post_max_size
upload_max_filesize
max_execution_time
You can either increase in your PHP configuration file or increase in your script using the ini_set function. Check the manual for more details. PHP Manual
I'm working with acquia-drupal 7 (just localhost for now), inside Microsoft WebMatrix.
I can't get my php upload limit to increase from the default 2MB. Having googled around I have done the following:
added to every existing htaccess:
php_value upload_max_filesize 10M
php_value post_max_size 10M
created php.ini file in every dir that had an htaccess (no php.ini files existed anywhere) containing the following:
upload_max_filesize = 10M
post_max_size = 10M
Restarted the site (through the Webmatrix GUI)
No apparent change whatsoever after any of this - my site still has the 2MB upload limit.
Thoughts?
The reason your changes are not taking affect are because you just created a php.ini file anew, rather than finding the one that is being used.
By definition, since you just created it, it won't be the one that exists in your php directory. :-)
But don't worry! There's an easy way to find the correct php.ini file that your site is using:
Go to /admin/reports/status on your drupal site. Here you will see information about which version of php and apache you're using, etc.
The line for 'PHP' on that page should have both the version of php you're using (something like 5.3.6) and a 'more information' link
Click on that link and you should be able to see detailed information about the php installation on your machine.
Find the line called 'Configuration File (php.ini) Path' on that screen and navigate to that to update it.
Just like you already knew, make sure you restart your server after any changes. :-)
Let us know if this fixes your problem!
Have you ever ran into a problem where you needed to upload relatively large files and still want to be able to manage these from the Drupal 7 administrative interface? If so, you may run into a situation like the one below:
You will notice the 12 MB text stating that we can only upload files that are 12 MB and under. In this case I needed this number to be a little bigger.
In order to do this you will need to modify your PHP settings in your php.ini file.
Note: You should make sure you know what you are doing and understand the consequences of increasing this number. In my case this is on a site that only users that I trust will be uploading files. If you allow any user to upload files, increasing this number can add an increased load on the server and possible eat up your disk space pretty quickly.
Now that you have been warned, here is how I was able to do this. I first found the php.ini file on my system. I am on an Ubuntu server so I was able to get to edit mine using vim like so:
vim /etc/php5/apache2/php.ini
Change the upload_max_filesize setting
The first step was to find the upload_max_filesize setting from 12MB to 30MB.
Change:
To:
Change the post_max_size setting
You may also need to modify the post_max_size setting. I changed the post_max_size php.ini setting from 20MB to 30MB.
Change:
To:
Restart Apache
You should check phpinfo to make sure your php.ini which you edited is the correct one.
I can upload small size files with no problem,
but fail when the size is more than 1M.
What's the matter?
You probably need to configure the upload_max_filesize directive, in your php.ini file : PHP will not accept an upload of a file that is bigger than what this directive defines.
And note that you might also need to adjust post_max_size -- which defines the total size of data that can be POSTed (And files upload are sent via POST).
You can also take a look at the Handling file uploads section of the manual, which can give you a couple of useful informations about files upload.
Are you sure you have upload_max_filesize set correctly in php.ini?
Edit you php.ini file to allow for larger uploads.
HERE's some info
You can call echo phpinfo() and then verify your upload_max_filesize and other php environment settings. Its very possible that your script is dying because one of the max limits is being exceeded.
Depending on your environment you can either use ini_set() to change the necessary values at run-time or you can simply edit your php.ini file to set the value permanently. Please note that not all php.ini settings can be changed at run time and if you do edit php.ini, you will need to restart Apache.
As said by others check your php.in for upload_max_filesize and post_max_size settings. If they are okay and if you are using a 3rd party script for uploading, make sure the script is not limiting the max file size by doing something like:
if( $_FILES["file"]["size"] > (1024 * 1024) ) // disallow uploads > 1MB
{
// max size exceeded.
}
I am trying to upload large files through my cms and was wondering how to change the php.ini file for heart internet.
Is this possible in shared hosting, if not are there any other work arounds?
Thanks in Advance
To override settings all you need to do is create either a php.ini or php5.ini file (if you are running PHP5) in your root directory. Then you can change settings like this:
upload_max_filesize = 20M ;
post_max_size = 20M ;
max_execution_time = 60 ;
This gives you maximum file size of 20MB and 60 second timeout.
As long as you keep this size within the allowed limits on your account, you can use this to increase the default size - which is 5MB.
It depends on whether your web hosting company allows you to override certain PHP settings or not. It might be possible to change some values but not others.
Secondly, the process for overriding settings differs depending on whether your hosting is IIS or Apache. If its Apache, try adding these two lines to your .htaccess file:
php_value upload_max_filesize 8M
php_value post_max_size 8M
This .htaccess file should do to the directory where your php upload script resides, or higher. I'd rather put it in the root directory.
Once done, create a php page containing this code:
<?php phpinfo( ); ?>
Compare the Local Value and Master Value of these settings to see if the changes are in effect.
There is no way to upload files over 50MB without breaking your terms and getting your account shutdown.
However if the terms were different, you could split the file into parts and join them together on the server side.
I moved away from heart internet and got my own server for this exact reason as they wouldn't even let me pay a premium to get the restriction removed (restricted from there end I think)
If it is shared hosting you probably won't be able to, I have also discovered that you cannot use ini_set to set the correct settings because the file upload occurs before your script is executed. So if you want to accept large files via a form to a PHP script you have to use php.ini.
You might be a work around though, you could use an open FTP account, upload large files form there and code a bit of script to ask the user what file they have uploaded, then you can manipulate (move / rename) to your hearts content.
Hi im quite new to PHP, i have created a form for very large csv files to be uploaded to my server. Some one mentioned to me that the browser can time out due to the uploading file being to big, is this true? and if so, can it be prevented?
Thanks for your help!
You need a proper value for the following php.ini settings:
max_input_time (not max_execution_time!)
upload_max_filesize
post_max_size
and maybe
memory_limit
There are some configuration directives that can cause large uploads to fail if their values are too small:
PHP
max_input_time Maximum time in seconds a script is allowed to parse input data, like POST, GET and file uploads
upload_max_filesize Maximum size of an uploaded file.
post_max_size Maximum size of post data allowed.
Apache
TimeOut Amount of time the server will wait for certain events before failing a request
LimitRequestBody Restricts the total size of the HTTP request body sent from the client
There are probably some more than this.
A good way to work around the poor handling of large file uploads in php, is to use an uploader like JUpload which will split the file into chunks before sending them. This also has the benefit for your users that they get a proper progress feedback while uploading, and they can upload multiple files in one go.
I was able solve this problem using the following settings, you could use different values but you get the idea:
For my server, I put these lines in a ".user.ini" file inside the script directory, your server may look for a different file, if you do a phpinfo('user_ini.filename') on the server it will spit out the file you need to put your values in
max_execution_time = 1800
max_input_time = -1
post_max_size = 100M
upload_max_filesize = 100M
memory_limit = 256M
When uploading very large files, you have to change 4 configuration variables:
upload_max_filesize
post_max_size
memory_limit
time_limit
Time limit may be increased at runtime with set_time_limit().
A script is allowed to run, by default, for something like 30 seconds. You can use the set_time_limit() function to alter this. Also, if your user will need to upload large files, you'll need to change the post_max_size and/or the upload_max_filesize values in your php.ini file.
Also, if you want to just extend your timeout limit globally, you can change max-execution-time in php.ini.
Yes it is true. File upload is done through a POST request and requests in general are subject to timeout. You should be able to reconfigure your environment for a longer request timeout.
It's not just timeouts that can cause problems. There are some limits on the maximum size of file that can be uploaded. These limits can be changed in the php.ini file:
post_max_size
upload_max_filesize
memory_limit
Check out http://uk.php.net/ini.core for details.
My answer is not directly related to your original question, but if you have a reverse proxy load balancer in front of your PHP script, the load balancer can timeout or block large uploads. Always check your load balancer's configuration if you support file uploads. Just like PHP, most load balancers default settings for uploads are pretty small.
If changing any of the above parameters doesn't seem to make any difference, it can be that a html form somewhere contains the name MAX_FILE_SIZE as a hidden field.
<input type="hidden" name="MAX_FILE_SIZE" value="10000000">
In the example above, any file over 10MB will not be uploaded.
