[php-src] Issue #11104: STDIN/STDOUT/STDERR is not available for CLI without a script

Issue: https://github.com/php/php-src/issues/11104 Author: jhdxr ### Description I ran into this issue when I try to access STDOUT with Symfony\Component\Process\PhpProcess I dig a bit and found out the three stream constants are not available for CLI are not available without a script or certain options (.e.g -a or -r) Here is a simplied way to reproduce. ```shell ~> php <?php var_dump(STDOUT); <ctrl+d> ``` Resulted in this output: ``` PHP Fatal error: Uncaught Error: Undefined constant "STDOUT" in Standard input code:1 Stack trace: #0 {main} thrown in Standard input code on line 1 ``` But I expected this output instead: ``` resource(2) of type (stream) ``` I try to trace why there is such constraint but it seems to be there for more than 10 years. Shall we fix it pr document this behavior? ### PHP Version PHP 8.2.4 ### Operating System irrelevant
