Enabling xdebug from environment variable

[Chi-teck]

I would like to enable/disable xdebug extension from environment variable which is configured in .env file. I put the following statement to the docker-compose.yml file but it did not work out by some reason.

PHP_XDEBUG: ${PHP_XDEBUG}

I guess this condition is evaluated to true when the variable holds an empty string.

php/8/templates/docker-php-ext-xdebug.ini.tmpl

Line 1 in c5b31a0

{{ if getenv "PHP_XDEBUG" }}

I am not familiar with go template syntax. Can it check more explicitly for emptiness of PHP_XDEBUG variable?

Sounds like #58 (comment) again. Its bitten many people, unfortunately.

We probably need to get rid of this env var completely, the default mode off should have close to 0 performance impact and in any case we still have PHP_EXTENSIONS_DISABLE

That makes sense. Thanks.
