[Process] defaultEnv not properly generated in PHP build-in webserver #44066
Description
Symfony version(s) affected
process 5.3.7
Description
The php-doc says
With
$env = null it will take the Enviroment of the current process. This is not allways true.Using the PHP Build-In Webserver (
php -S localhost:80) $_ENV is empty (but getenv() is not), sosymfony/src/Symfony/Component/Process/Process.php
Line 1672 in f7d70f1
gives unexpected result. Especially the PATH variable remains unset, which leads to unfound binaries
How to reproduce
Use php build in webserver (see above) and use e.g
$p = new Process(['pdflatex'], __DIR__, null)(set $env = null)
-> PATH Variable is not set in $_ENV only in getenv()
Possible Solution
Use getEnv() instead of $_ENV or check for
if (php_sapi_name() === 'cli-server') {Additional Context
php -S is (often) used in local development environments. Missing PATH Variables can be a big issue there.
