Is CiviCRM 4.6.x compatible with newer version of PHP, 7?

2 Answers 2


No, it is planned for 4.8, but could use some help (with funding or investigating issues).

    Commenting since this answer was accepted -- PHP 7 compatibility was introduced in 4.7.12 ( civicrm.org/blog/totten/… ). Rationally, it installs and passes the test-suite in PHP 7, so it works, but it's new and could have unforeseen issues. Risk-averse folks should stay with PHP 5 for now; early-adopters can get going with their early adoption.

  • And since someone will come here looking, issues.civicrm.org/jira/browse/CRM-19941 is the issue tracker for compatibility with PHP 7.1.

It is possible to help to identify the to-do's for CiviCRM to become php7 compatible in question: What are the minimum and recommended changes to CiviCRM to support PHP 7?

Please do so, so at least an initial scope will become clear.
