Bug description: Invalid escaping for passthru() in CLI
Description:
------------
When I run a PHP script which uses passthru() to execute a command with
characters that need escaping, the escaping is incorrect when the script is
run from the command line, but it is fine when the script is run from
within Apache. This was causing the script
"ext/standard/tests/file/bug22414.phpt" to fail when I attempted to run
"make test" after building PHP 5.2.5 on RHEL3. I have created a simplified
script for this report to demonstrate the problem, though I will note that
I can also reproduce it reliably with "bug22414.phpt".
I should mention that I also tried my test script from the command line in
Mac OS X 10.5 running PHP 5.2.5 and Ubuntu 7.10 running PHP 5.2.3 and it
worked correctly in both cases. So, my suspicion is that there is an older
library on RHEL3 which is causing the parsing the be incorrect. It passes
all the requirements checks made by './configure', though.
I ran the test code below using the '-n' option to PHP so as to eliminate
my "php.ini" as the problem.
Reproduce code:
---------------
header("Content-Type: text/plain");
$textEscaped = escapeshellarg("Tim's Test");
print("Before: {$textEscaped}\n");
print("After: ");
passthru("/bin/echo {$textEscaped}");
Expected result:
----------------
Before: 'Tim'\''s Test'
After: Tim's Test
Actual result:
--------------
Before: 'Tim'\''s Test'
After: Tim\s Test'
