#26532 [NEW]: passthru does not work with subshells

From: arne at fotos dot dyndns dot biz Operating system: LINUX PHP version: 4.3.4 PHP Bug Type: Program Execution Bug description: passthru does not work with subshells Description: ------------ when I have 2 files t and t2 and I try to diff them with diff <(cat t) <(cat t2) LINUX-shell produces 2 meta-files (/dev/fd/[00-99]) to pipe into the diff command. Thats usual, thats basic. If I try to use the same command in passthru("diff <(cat t) <(cat t2)"); I run into errors: sh: -c: line 1: syntax error near unexpected token '(' sh: -c: line 1: 'diff <(cat t) <(cat t2)' The files are in the PATH and I can see output of t when I do: passthru("cat t"); what means that cat is available too.
