PHP Version & Configuration in RemarkablePanel

Switch PHP version

Open the website → PHP.

Select the PHP version from the dropdown (8.1, 8.2, 8.3 available).

Click Save. The change applies immediately.

PHP 8.2+ is significantly faster than 7.4 and receives active security updates. Only use older versions for legacy code that hasn't been updated for modern PHP.

Customize PHP settings

From the same PHP page, override individual php.ini values:

Setting	Default	Recommended for WordPress
memory_limit	128M	512M
upload_max_filesize	8M	64M
post_max_size	8M	64M
max_execution_time	30	300
max_input_vars	1000	5000

Enter values in the PHP Settings section and click Save.

Check the active PHP version

Create a temporary file in the website’s document root:

echo "<?php echo phpversion();" > /path/to/httpdocs/phpcheck.php

Visit https://yourdomain.com/phpcheck.php: it prints the PHP version. Delete the file afterwards.

PHP error logging

To enable PHP error logging without displaying errors to visitors:

In PHP Settings, set:

display_errors = Off
log_errors = On
error_log = /path/to/httpdocs/php-errors.log

Check the error log via File Manager or SFTP.
