PHP 5.6.0RC4 is now available
Change effective on 14 August 2014
PHP 5.6.0RC4 is now available as an experimental runtime on Heroku. This version supersedes previously available release candidates.
To select it, use an appropriate minimum-stability setting or a stability flag for the php package in composer.json; for example:
{
"require": {
"php": "~5.6.0@RC"
"monolog/monolog": "~1.7"
}
}
This will require that you have a corresponding version of PHP installed locally when you run composer update.
If you have no user-land packages as dependencies (and thus no composer.lock is generated where stability flags can be read from), you must use minimum-stability:
{
"require": {
"php": "~5.6.0RC4"
},
"minimum-stability": "RC"
}
