PHP settings are reviewed and updated by uploading the two corresponding files to a hosted site. To view the current PHP settings, a phpinfo script. To make changes to those settings, a user.ini settings file.
The syntax would be added to a PHP file, uploaded to the site and viewed in a browser. An example script can also be found in the .zip in the Sample section below.
A site's PHP settings can be adjusted by creating a user.ini file, adding the appropriate syntax (see Sample), then uploading that file to the document root of the site via FTP.
An example of a common update is the post_max_size and upload_max_filesize settings, often changed to allow plugin and theme uploads through WordPress.
For PHP 7.0, the settings default to 8 MB and 2 MB, respectively, which can lead to some upload errors within WordPress. To increase those settings, for example to 60 MB, create a new text document with the following syntax:
post_max_size = 60M
upload_max_filesize = 60M
Once the user.ini has been uploaded, to see the setting updates reflected on the site, first recycle the application pool at DiscountASP Control Panel > IIS Tools > Recycle ("Recycle App Pool" if IIS 7).
Once recycled, the new Local Value should be reflected when reviewing a phpinfo script.
