This library misses a detailed documentation, but it is used in various production
projects for a long time, so you may use it too. Below is the content of
Debug_ErrorHook: Intercept PHP errors (including fatals) and process them (e.g. send to E-mail).
(C) Dmitry Koterov, http://en.dklab.ru/lib/Debug_ErrorHook/
This library allows to intercept PHP errors (including fatal!) with their
context (file name, line number, often - stack trace, environment etc.)
and do some work with this information. You may add any number of
hooks which will be called in case of errors.
The most common usage is to send PHP notices, warnings and even fatal
errors to developer's E-mail. Of course this sending is wise: if the
same error already happened within N seconds, it will not be resent,
so the mailbox is never overloaded, and sendmail program cannot crash
the whole system even if your site is very popular.
Commony errors and notices are sent to web server's logs and die there.
Nobody monitors server logs oftenly. If these errors are sent do developers'
emails, developers could react immediately and fix them. It is quite handy,
especially just after production deployment, and it works great especially
for fatal errors.
Usage sampleExecute this in your script's bootstrap code:
$errorsToMail = new Debug_ErrorHook_Listener();
"/tmp/errors", // lock directory
300 // do not resend the same error within 300 seconds
// Attention! When $errorsToMail is destroyed (e.g. went out of
// scope), error hooks are removed. Hooks are active till $errorsToMail's
// destructor execution. So you should commonly save $errorsToMail somewhere
// in a safe place (e.g. in $GLOBALS or in a class static property) and
// be sure it is not destroyed until your script is finished.
Be sure to set error_reporting(E_ALL) to catch all notices. To test notice
emailing, execute something like:
You will receve 2 mails at email@example.com mailbox. First:
Subject: [ERROR] E_NOTICE: Undefined variable: a at script.php on line 10
E_NOTICE: Undefined variable: a
at script.php on line 10
<content of $_SERVER>
<content of $_COOKIE>
<content of $_GET>
<content of $_POST>
<content of $_SESSION>
Second mail will contain information about your fatal error. (Unfortunately
PHP does not allow to get stack trace for fatal errors, but other information
will be mailed correctly, including file name, line number and superglobals
