Changing a site's PHP version - Pilothouse-App/Pilothouse GitHub Wiki

Pilothouse supports all versions of PHP currently supported by the PHP maintainers. At the time of this writing, that means the available PHP versions in Pilothouse are:

The global default PHP version is 7.0, which will be used if no flags are present, or if no site-specific PHP version is defined. You can change the global default PHP version if you wish.

To override the global default PHP version on a site-by-site basis, define the site's default in the site-specific configuration file.

You can override the site-specific default (or the global default) at any time by including a query arg or cookie in the request. Either set a cookie in the browser named php containing the desired php version, or add a query argument named php to the URL, like so:

http://wp.dev/?php=5.6

To can use the bookmarklets below to set a cookie, or run the following code in the console, changing 7.0 to the desired PHP version:

document.cookie='php=7.0;path=/;';

The following bookmarklets can be added to your favorites bar to quickly change the PHP version cookie which will be persistent for the duration of the browser session:

Use PHP 5.6

javascript:(function(){document.cookie='php=5.6;path=/;';})()

Use PHP 7.0

javascript:(function(){document.cookie='php=7.0;path=/;';})()

Use PHP 7.1

javascript:(function(){document.cookie='php=7.1;path=/;';})()

Use PHP 7.2

javascript:(function(){document.cookie='php=7.2;path=/;';})()

In summary, the process for determining which PHP version is used for a request uses the following hierarchy:

Query arg, if present
Cookie, if present
Site-specific default, if present
Global default
