Generic error/exception handler
|

| I seem to have messed up on what I posted to you. Here is example code
that does what I was looking for - a generic catch all (or at least
catch most) error handler for PHP5. The point is that I did not want
to test for errors, nor throw exceptions. I just want to catch all
errors/exceptions that happen so I can deal with them gracefully.
<?
// see http://php.net/error_reporting
error_reporting(E_ALL);
// see http://php.net/set_error_handler
function myErrorHandler($errno, $errstr, $errfile, $errline) {
// a fifth argument (context) is passed, whether defined or not
print "Standard error in line $errline:";
print "<br>\n$errstr\n<br>";
}
set_error_handler('myErrorHandler');
// see http://php.net/exceptions
try {
$foo = 7 / 0; // execution resumes after a warning
$bar = new COM("speling.error"); // exception is thrown
// exception thrown above => line below not executed
print "<br>\nThird line of the try";
} catch (Exception $e) { // generic exception handler
print "<br>\nThrown exeption in line " . $e->getLine();
print "<br>\n" . $e->getMessage() . "\n<br>";
}
print "<br>\nEnd of routine";
?>

Well, at this point, an error and an exception are different
beasts and must be handled differently. You can, however, try
combining two handlers into one:
function handleItAll ($arg1, $arg2=NULL, $arg3=NULL, $arg4=NULL) {
if (is_object($arg1)) {
// exception thrown; handle it
}
if (is_numeric($arg1)) {
// error triggered; handle it
}
}
set_error_handler('handleItAll');
set_exception_handler('handleItAll');
Cheers,
NC
