Drupal::MINIMUM_PHP

Minimum allowed version of PHP for Drupal to be bootstrapped.

Below this version:

• The installer cannot be run.
• Updates cannot be run.
• Modules and themes cannot be enabled.
• If a site managed to bypass all of the above, then an error is shown in the status report and various fatal errors occur on various pages.

Note: To prevent the installer from having fatal errors on older versions of PHP, the value of this constant is hardcoded twice in core/install.php:

• Once as a parameter of version_compare()
• Once in the error message printed to the user immediately after.

Remember to update both whenever this constant is updated.
