Reviewing and updating PHP settings

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 / .user.ini settings file.

 

 

phpinfo is used to display the current PHP configuration for the site / server.  Specific parameters can be passed to customize the output or to display all information the following syntax can be used:

 

<?php
phpinfo();
?>

 

A site's PHP settings can be adjusted by creating a user.ini or .user.ini file, adding the appropriate syntax, then uploading that file to the document root of the site via FTP.  The file name depends on the version of PHP being used, which can be reviewed at Winhost Control Panel > Sites > the applicable domain name > PHP Version.

 

 

 

If the PHP version is 5.3 ,5.6 or 7.0 the file name is:  user.ini

For any other PHP version the file name is:  .user.ini

 

 

 

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 7.2, 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
