[php] Change the maximum upload file size

I have a website hosted on a PC I have no access to. I have an upload form allowing people to upload mp3 files up to 30MB big. My server side script is done in PHP.

Every time I try and upload a file, I receive an error claiming that the file exceeds the maximum size allowed, so I need to increase the size. My research on the web suggested changing the .htaccess file which I do not have access to, so that won't work. Others suggested that I should add a custom php.ini file to my root which did not work. Any other suggestions?

If you edited the right php.ini file, restarted Apache or Nginx and still doesn't work, then you have to restart php-fpm too:

sudo service php-fpm restart 

I had the same problem and i created a .user.ini file and put it in the directory in which the upload script was located. Than inside that file i set these these two values:

  upload_max_filesize = 40M

  post_max_size = 40M

and it worked great for me!

I have the same problem in the past .. and i fixed it through .htaccess file

When you make change on php configration through .htaccess you should put configrations in IfModule tag, other that the Internal server error will arise.

This is an example, it works fine for me:

<IfModule mod_php5.c>
   php_value upload_max_filesize 40M
   php_value post_max_size 40M
</IfModule>

And this is php referance if you want to understand more. http://php.net/manual/en/configuration.changes.php

1. Open the php.ini file.

2. Search keyword like upload_max_filesize in php.ini.

3. Then change the size of file.

   upload_max_filesize = 400M

4. Need to change the max post value.

   post_max_size = 400M

the answers are a bit incomplete, 3 things you have to do

in php.ini of your php installation (note: depending if you want it for CLI, apache, or nginx, find the right php.ini to manipulate. For nginx it is usually located in /etc/php/7.1/fpm where 7.1 depends on your version. For apache usually /etc/php/7.1/apache2)

post_max_size=500M

upload_max_filesize=500M

memory_limit=900M

or set other values. Restart/reload apache if you have apache installed or php-fpm for nginx if you use nginx.

many times i have noticed that site wit shared hosting do not allow to change settings in php.ini files. one also can not even crate .htaaccess file at all. in such situation one can try following things

ini_set('upload_max_filesize', '10M');
ini_set('post_max_size', '10M');
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);

I resolved this issue by creating a file called .user.ini in the directory where the PHP file scripts reside (this means any PHP script in this directory gets the new file size limit)

The contents of .user.ini were:

upload_max_filesize = 40M
post_max_size = 40M

I also had this issue, and fixed it by setting this setting in /etc/nginx/nginx.conf

client_max_body_size 0;

0, as in unlimited.

And also, if you have a reverse proxy running with nginx, that server should also have this setting (This is what threw me off here)

With WAMP it's all pretty easy

WAMP Icon > PHP > PHP Settings > upload_max_filesize = nM > n = (2M, 4M, 8M, 16M, 32M, 64M, 128M, 256M, 512M, or Choose (custom)).

Service(s) reload automatically.

But, if you truly have no access to the server, you might want to explore writing a chunking API.

I had the same problem. I have tried three ways that were usually suggested:

1. functions.php
2. php.ini
3. .htaccess

none if which solved my problem. I am using godaddy and came across a suggested solution which was:

1. got to Web Hosting, then Manage
2. Under Software select Select PHP version
3. Select Switch to PHP Options found on the top right corner of the table in font color: blue
4. On the bottom most part, you'll probably have upload_max_filesize = 2M
5. Now, feel free to change it
6. Be sure to click the Save button!
7. Now go to your wp-admin panel, select Media then Add

Voila! Now you have a different max upload file size :)

To locate the ini file, first run

php -i | grep -i "loaded configuration file"

Then open the file and change

upload_max_filesize = 2M
post_max_size = 2M

replacing the 2M with the size you want, for instance 100M.

I've got a blog post about with a little more info too http://www.seanbehan.com/how-to-increase-or-change-the-file-upload-size-in-the-php-ini-file-for-wordpress

You can change it via an .htaccess file.

.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 40M
php_value post_max_size 42M

You can also use ini_set function (only for PHP version below 5.3):

ini_set('post_max_size', '64M');
ini_set('upload_max_filesize', '64M');

Like @acme said, in php 5.3 and above this settings are PHP_INI_PERDIR directives so they can't be set using ini_set. You can use user.ini instead.

Non of those solutions work for me!! (already set to 32M by default).The problem is in most case max_allowed_packet

I am working on localhost and using MAMP.

Here is solutions;

1. If you don't have my.ini

Add

--max_allowed_packet=168435456

To

...\MAMP\bin\startMysql.sh

2. If you have my.ini

Under

[mysqld]

Add

max_allowed_packet=100M

DONE!

Three things you need to check.

upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file exactly.

All of these three settings limit the maximum size of data that can be submitted and handled by PHP.

Typically post_max_size and memory_limit need to be larger than upload_max_filesize.

So three variables total you need to check to be absolutely sure.

As changing globally is somewhat risky, I was trying to increase max upload value for a single script big_file_upload.php. For some reason ini_set didn't help. After some reasearch I've come up with this. Put it in .htaccess (unless name changed via AccessFileName)

<If "%{REQUEST_URI} == '/subfolder/big_file_upload.php'" >
php_value upload_max_filesize 200M
php_value post_max_size 200M
</If>
<Else>
php_value upload_max_filesize 1M
php_value post_max_size 1M
</Else>

Worked for me.

Perhaps this should be a comment to @seanb123 and @Fredrick Gauss commenting on his comment, but for me in Drupal 8.1 with PHP 7 the file I needed to modify was located here:

/etc/php/7.0/apache2/php.ini

I modded probably four other php.ini files, including the one my system called the "Loaded Configuration File" (php -i | grep -i "loaded configuration file") and the one found on the info.php page but none of them helped. The key to discovering the correct path was found on a site from 2012. They said the path "/etc/php5/apache2/php.ini" was deprecated even BACK THEN but it gave me a clue where to find it. For PHP7 it's a little different than in PHP5 but the concept is the same.

Maybe this will help some otherwise helpless schmuck like myself.

That being said, the answer to the OP in my case would be that someone with admin privileges on the box would have to do it.

The site that helped me: http://www.evilbox.ro/linux/remove-ispconfig-maximum-upload-size-of-2m-for-wordpress/

This is also addressed here: Import file size limit in PHPMyAdmin

EDIT: the full text of my note to myself:

In order to change the max upload size, edit upload_max_filesize and [if needed?] post_max_size in /etc/php/7.0/apache2/php.ini (or in older versions: /etc/php5/apache2/php.ini )

/etc/init.d/apache2 restart

EDIT AGAIN: since you're importing big files you may need to change the timeout for processing them. In my case, the file named, "config.default.php" was found at /usr/share/phpmyadmin/libraries/config.default.php with the variable $cfg['ExecTimeLimit'] = 300; I changed mine to 900 for a huge import, for instance. Afterward you need to restart apache

Well, I would like to add my 2 cents here.

I'm using shared webhosting and I tackled this problem many times, tried to resolve it on my own but to no avail. Finally I managed to resolve it through checking various web sources and contacting my hosting service provider. My questions were "How can I change php value memory_limit in shared webhosting?", "How can I change php value upload_max_filesize in shared webhosting?", "How can I change php value max_input_vars in shared webhosting?", "How can I change php value max_execution_time in shared webhosting?", "How can I change php value max_input_time in shared webhosting?" and many more by configuring or changing php.ini or .htaccess file. I tried to change them but problems arose. Finally I contacted my hosting provider, and it turns out that I set my php to native, they changed it to php 5.6, here is their answer:

"Your PHP was set to 'native' mode which means you can't override those values. I've changed you to just '5.6' so you should be good to go."

After that I connected my website through ftp Filezilla, also don't forget to make both your ftp service to show hidden files, and your local computer to do so, because .htaccess file was hidden in my local laptop and in my website. It was available in public_html folder, I just downloaded it and added the following codes to the end of the file and then uploaded it back to the server:

php_value memory_limit 256M
php_value post_max_size 256M
php_value upload_max_filesize 64M
php_value max_input_vars 1800
php_value max_execution_time 300
php_value max_input_time 300

Everything is working properly for the time being, if any of you overcome with some problems please write here and warn me so that I can change the above-shown codes. By the way, I also upload some pictures which shows the change.

One more thing I almost forgot to mention ZipArchive installation on your shared webhosting service, I managed that requirement to tick by just going to php settings through my cpanel, click on php selector extensions and then tick zip section, that's all.

Thanks.

PS: I'm open to good practices, and if you see any bad practice here please let me know, I'll try to change them. Thanks.
