The True Exception Handlers in PHP and Javascript

@Jordan Hall tweets true exception handlers in PHP an Javascript.

try {
  // something
} catch (e) {
   window.location.href = "http://stackoverflow.com/search?q=[js] + "
                        + e.message;
}

try {
  // something
} catch (e) {
   window.location.href = "http://stackoverflow.com/search?q=[js] + "
                        + e.message;
}

So if things go wrong, the page will be redirected to stackoverflow for answers.

Similarly, here is the PHP versions:

try {
  // something
} catch (Exception $e) {
  header("Location: https://stackoverflow.com/search?q=[php] ".$e->getMessage());
}

try {
  // something
} catch (Exception $e) {
  header("Location: https://stackoverflow.com/search?q=[php] ".$e->getMessage());
}

You can split the try-catch into two files and let server automatically wrap your PHP code inside this big try-catch.

You will need phps auto_prepend_file and auto_append_file directives. and modify the .htaccess file.

1 2	php_value auto_prepend_file "/path/to/file/before.php" php_value auto_append_file "/path/to/file/after.php"

php_value auto_prepend_file "/path/to/file/before.php"
php_value auto_append_file "/path/to/file/after.php"

Put the following in before.php

try {

try {

and put the rest in after.php

} catch (Exception $e) {
  header("Location: https://stackoverflow.com/search?q=[php] ".$e->getMessage());
}

} catch (Exception $e) {
  header("Location: https://stackoverflow.com/search?q=[php] ".$e->getMessage());
}

Alternatively, you can put these definitions in php.ini (requires cgi-mode, affects the whole webserver).

1 2	auto_prepend_file = "/path/to/file/before.php" auto_append_file = "/path/to/file/after.php"

auto_prepend_file  = "/path/to/file/before.php"
auto_append_file   = "/path/to/file/after.php"
