I had uploaded three files to the server in php. Smaller files are uploaded correctly but
when uploading larger files I get an error.
How to upload large files in php?
If the smaller files are uploaded successfully but not the larger files, then most probably the problem is caused by the php.ini settings.
Did you check what is Maximum allowed size for uploaded files defined in your php.ini file? Find the following line in your php.ini file, there you can define the size. For example:
upload_max_filesize = 10M
You have to set your php.ini to accept larger file size: you are interested in two variables i think:
upload_max_filesize // the max size a file can have when uploaded
max_post_size //the max size of a POST call
Look here for reference
As Nicola points out, there are some variables in the php.ini you should look for:
For example, in php.ini:
memory_limit = 384M
post_max_size = 256M
upload_max_filesize = 200M
What Nicola didn't mention is that constraints may also be in place on your web server. If it's nginx for example, you need to make adjustments to the configuration of your virtual host to support larger files ...
For nginx:
client_max_body_size 150m;
For Apache:
The apache webserver has a LimitRequestBody configuration directive that restricts the size of all POST data regardless of the web scripting language in use. Some RPM installations sets limit request body to 512Kb. You will need to change this to a larger value or remove the entry altogether.
increase the memory limit with .htaccess or ini_set() function in php

My problem is when I upload a file exceeds the limits I set in the script (5 MB) it shows this warning in the top of the website:
Warning: POST Content-Length of 32485176 bytes exceeds the limit of 20971520 bytes in Unknown on line 0
For example here I uploaded a file more than (30 MB) but when I upload a file more than (5 MB) and less than 30 (or not that large) it doesn't show that warning and shows only the error I wanted from the code :
if($file_size > 5000000) { echo
"<div>
You Can't Upload More than 5MB of the file
</div>";
}
I am working on localhost and this error is appearing every time, I know how to fix it in localhost by modifying php.ini, but the website is online too and this error isn't showing in the website.
Is there a way to limit the uploaded files sizes to (5 MB) and not modifying the php.ini file because I don't think I have the permission from the hosting company to change the apache config for the limits.
I hope my question's clear.
Thanks for helping.
You can change it via .htaccess file in your php file directory...
.htaccess files are stored in the same directory as your .php files are. They modify configuration for that folder and all sub-folders. You simply use them by creating an .htaccess file in the directory of your choice (or modify it if present).
The following should enable you to increase your upload limit (if the server provider allows PHP config changes via .htaccess).
php_value upload_max_filesize 100M
php_value post_max_size 105M
you just settings at php.ini
then set :
upload_max_filesize = 1000M;
post_max_size = 1000M;
then restart your server..
Hello go To You Xampp Directory and then go as follow :-
xampp\php\php (configuration file)
Find for post_max_size (make sure you are at top of file)
then change
post_max_size = 2M To post_max_size 1000M
upload_max_filesize = 8M To upload_max_filesize = 1000M
and now restart you apache server or if still error restart apache , mysql too
Please Let Me know if any concern
I have 3 inputs (2 text inputs and 1 file input). All inputs is required.
When I upload a zip file (13MB). I do not get any data from 3 inputs so the validation failed.
I try reduce the file size (6MB) then it's OK.
You need to set the value of upload_max_filesize and post_max_size in your php.ini :
; Maximum allowed size for uploaded files.
upload_max_filesize = 13M
; Must be greater than or equal to upload_max_filesize
post_max_size = 13M
Rather than 13M, I suggest you set it to a little bit bigger like 50 MB.
After modifying php.ini file(s), you need to restart your HTTP server to use new configuration.
If you can't change your php.ini, you're out of luck. You cannot change these values at run-time; uploads of file larger than the value specified in php.ini will have failed by the time execution reaches your call to ini_set.
See the Description of core php.ini directives.
I got the problem with my web server.
I configured PHP to have max upload size 300MB. I changed 2 options in php.ini
php_value upload_max_filesize 300MB
php_value post_max_size 300MB
This works fine.
But recently i noticed very big file in /tmp folder (this is temp folder for PHP).
There were 3 files of a size 1.5GB and continue growing . file names were like temp php files /tmp/php** (** some random code).
And i checked that process writing to these files were my PHP script i created for uploading.
So my question is why PHP upload and post limit didn't affect on these files? What can be the reason? Maybe PHP saves all uploaded data to temp dir first and only after this calculates a size and check if it is good or not?
I appreciate any comments.
UPDATE. Can this be something like - http client sends a request without content-length heder so php can not use post_max_size to limit affect. And PHP writes everything to the disk because doesn't know what is the site of POST request and file in it?
You need to set the value of upload_max_filesize and post_max_size in your php.ini :
; Maximum allowed size for uploaded files.
upload_max_filesize = 300M
; Must be greater than or equal to upload_max_filesize
post_max_size = 300M
or in .htaccess
php_value upload_max_filesize 300M
php_value post_max_size 300M
Try to set a new tmp directory with larger space and no limit rather than the system default (/tmp). You can do so either by changing the default directory in the php.ini file:
upload_tmp_dir = /scratch/custom_temp
or overwrite inside the php script:
<?php
ini_set('upload_tmp_dir', '/scratch/custom_temp');
?>
I want to change the max upload file limit dynamically. means by not changing the php.ini file on server.
Whenever user had uploaded more then 2 mb then my upload limit should be change.
I want to do all this through php.
Thanks in advance.
The limits enforces by upload_max_filesize are enforced before the php script is run, so the setting cannot be changed dynamically with ini_set.
For more information on the file upload ini settings and where they can be changed, see:
- http://php.net/manual/en/ini.core.php#ini.sect.file-uploads
- http://php.net/manual/en/configuration.changes.modes.php
Assuming by "user" you mean a visitor to your site, there are really only two methods you can enforce such a limit without the file reaching its final destination:
1) Before the upload has occurred: On the client side. You could definitely do this using a java-based uploader. Whether you can get the filesize of the selected file using javascript, I don't know.
2) After the file is uploaded to the server, but before you move it to the final destination (before you run move_uploaded_file)
Try this:
ini_set('upload_max_filesize', your_value_here);
Make sure also that you have specified the correct acceptable settings for:
file_uploads
upload_max_filesize
max_input_time
memory_limit
max_execution_time
post_max_size
If you can't modify your php.ini, you might be able to do it with a .htaccess file:
php_value upload_max_filesize 50M
php_value post_max_size 50M
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.
