Hi Jack,
here is a link that can be of help
http://bugs.php.net/bug.php?id=22839
also you can use custom error handler function , catch errors and
write to stderr
============
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
$ERROR='';
switch ($errno) {
case E_USER_ERROR:
$ERROR = "<b>My ERROR</b> [$errno] $errstr<br />\n";
$ERROR.= " Fatal error on line $errline in file $errfile";
$ERROR.= ", PHP " . PHP_VERSION . " (" . PHP_OS . ")<br />\n";
$ERROR.= "Aborting...<br />\n";
break;
case E_USER_WARNING:
$ERROR= "<b>My WARNING</b> [$errno] $errstr<br />\n";
break;
case E_USER_NOTICE:
$ERROR= "<b>My NOTICE</b> [$errno] $errstr<br />\n";
break;
default:
$ERROR = echo "Unknown error type: [$errno] $errstr<br />\n";
break;
}
if($ERROR){
$stderr = fopen('php://stderr', 'w');
fwrite($stderr, $ERROR );
fclose($stderr);
}
/* Don't execute PHP internal error handler */
return true;
}
set_error_handler("myErrorHandler");
//code .....
==========================
I guess you can achieve what you need by one of those 2 concepts
Cheers.

How can I implement in PHP, a script which redirects stdout to stderr,

I can redirect stdout to stderr when invoking PHP like so:
php script-name >&2
However I want to perform this redirection within the script itself.
The solution I currently use is output buffering:
ob_start();
// Call library code
fwrite(STDERR, ob_get_contents());
ob_end_clean();
However I wonder if there's a more efficient way, so that output
appears
on stderr immediately, rather than waiting for fwrite(STDERR,
ob_get_contents());
My reason for wanting this is to create a Subversion pre-commit hook
using PHP_CodeSniffer: http://pear.php.net/package/PHP_CodeSniffer
I want:
1) Commits to our Subversion repository to be checked against our
coding
standard with PHP_CodeSniffer
2) Commits to fail when PHP_CodeSniffer returns an error
3) PHP_CodeSniffer's report to be displayed to the Subversion user, so
they can fix any problems
I achieved 1) and 2), but PHP_CodeSniffer prints its report to stdout
and Subversion only displays stderr to the user, not stdout. So to
make
this pre-commit hook fool proof, I want it to redirect
PHP_CodeSniffer's
report to stderr.
Anyone have better suggestions than output buffering?
Much thanks, Jack
