how to know the laravel php base?

just create a php file and write phpinfo(); it will inform you about your php server

php has a constant called

PHP_VERSION

or a mthod

phpversion()

. Any of them will always show you what version you are using

thanks @shakti and @AhimbisibweRoland

There's also version_compare() if you need to do something, e.g. :

if (version_compare(phpversion(), '7.0.0', '>=')) {
    require 'iknow/iknow/mysql_shim.php';
}
