Cara menggunakan php getenv returns false

The main issue of env vars is that their values can only be strings and your application may need other data types (integer, boolean, etc.). Symfony solves this problem with "env var processors", which transform the original contents of the given environment variables. The following example uses the integer processor to turn the value of the # config/packages/framework.yaml framework: router: http_port: '%env(int:HTTP_PORT)%'16 env var into an integer:

6.2

The # config/packages/framework.yaml framework: router: http_port: '%env(int:HTTP_PORT)%'75 env var processor was introduced in Symfony 6.2.

It is also possible to combine any number of processors:

PHP

It's also possible to add your own processors for environment variables. First, create a class that implements EnvVarProcessorInterface:

1 2 3 4 5 6 7 8 9 10 11 12 13 146# config/packages/framework.yaml framework: router: http_port: '%env(int:HTTP_PORT)%'15

To enable the new processor in the app, register it as a service and tag it with the # config/packages/framework.yaml framework: router: http_port: '%env(int:HTTP_PORT)%'76 tag. If you're using the , this is already done for you, thanks to .
