Logging PHP and JavaScript errors to same window makes debugging easier. It also might be the cure to cancer and bring world peace. In general…
In a recent PHP + JavaScript project I realized how annoying it is to have debug information in more than one place. For PHP I use PEAR::Log package. Log is written to file. For JavaScript I use Firebug. Log is written to Firebug console. When something goes wrong you must switch between browser and terminal windows.
There must be a better way. I like both PEAR::Log and Firebug. Obvious thing was to combine them. Result is Firebug handler for PEAR::Log. It can currently be found only in CVS. Hopefully be handler will be included in next release of PEAR:Log package.
Example PHP usage below.
$log = &Log::singleton('firebug', '', 'PHP',
array('buffering' => true),
PEAR_LOG_DEBUG);
$log->log('Debug lorem ipsum.', PEAR_LOG_DEBUG);
$log->log('Info wisi enim ad minim veniam', PEAR_LOG_INFO);
$log->log('Warning est usus legentis in', PEAR_LOG_WARNING);
$log->log('Error est notare quam', PEAR_LOG_ERR);
If you have Firebug installed, enable it and check Log Firebug test page. You can also redirect all PHP errors to Firebug console.
UPDATE 20070208: You might want to check FirePHP which provides different approach. FirePHP is Firefox extension built on top of Firebug. It modifies request headers to include Accept: text/firephp. Debug data is sent back using text/firephp section of multipart/mixed HTTP response. Using FirePHP is more complicated but at the same time it can provide you with more flexibility.
