How do I increase the PHP upload limit?

Overview

Every installation of PHP comes with default settings which are usually fine for most websites. Occasionally, the needs of a website makes it necessary to adjust these PHP settings. For example, your site may need to upload files larger than the current PHP upload limit allows. In that case, you would need to create a php.ini (phprc) file and update this value.

The DreamHost phprc file

The standard term for a PHP configuration file is php.ini. However, DreamHost uses the term "phprc" file instead. This acts the same way – only the name is different. In this article, only the term phprc is used.

Some variables (in particular, memory_limit, post_max_size and upload_max_filesize) are subject to internal limitations; increasing them significantly beyond the default values will not work correctly and will cause issues with your site.

Increasing the filesize upload limit

The default size limit for uploading files is 64MB, which may be far too small for your needs. If you need to raise this limit, you must create a phprc file. View the following articles for instructions on how to create a phprc file.

If the file already exists, view the following articles for instructions on how to update it (depending on if you're using an FTP client or SSH):

To increase that limit to 100MB, use the following directives:

upload_max_filesize = 100M
post_max_size = 105M
max_execution_time = 500
max_input_time = 500

To upload large files, post_max_size should be larger than upload_max_filesize.

Kill off all running php processes

Make sure to kill running php processes to ensure your new settings take effect.

Confirming your changes

After you've edited the file and killed off all PHP processes, you should check to confirm the values have updated. You can do this by creating a phpinfo.php file.

If you do not see your changes have updated, try killing off your PHP processes again:
