ERROR cases

[hackalive]

Hi guys, two things, where can I get a complete list of possible error cases (eg E_USER_NOTICE) and secondaly how can I make my own for the custom error handler I have

 

thanks in advance for any/all help

You can only use the E_USER_* constants (NOTICE, WARNING, ERROR, DEPRECATED) You can define your own error constants but these are not usable by the built-in error handlers (unless they share the same integer value).

ignace in regards to your response to the second question could you please clarify it. Can I have my own eg E_USER_AA? if so how, I am using my own error handler so I would like to know if I can do this

Yes you can have your own error constants but you can't use these with any built-in error-handling functions.

okay thanks ignace, so how do I build them?

What do you exactly want to achieve? You can also just use exception's:

 

try {
    $do->something();
} catch (ServerMadeBooBoo $e) {
    echo 'Server made BooBoo.';
    exit(0);
} catch (UserMadeBooBoo $e) {
    echo 'You made BooBoo. You bad BooBoo.';
    exit(0);
}

 

You can also go for the more complex and use a Chain-Of-Responsibility (CoR) pattern:

 

$errorHandler = new ServerMadeBooBoo(new UserMadeBooBoo());

$errorHandler->handle(MY_ERR_CBOOBOO); // Output: You made BooBoo. You bad BooBoo.

 

So what do you exactly want to achieve?

okay so I have on index.php

 

function errors($errno, $errstr, $errfile, $errline)
{
    switch ($errno) {
case E_TEST_WARNING:
	echo "<b>DEPRECATED</b> [$errno] $errstr [$errfile on $errline]<br />\n";
	break;
}
    return true;
}

set_error_handler("errors");

trigger_error("IC_00_00_test",E_TEST_WARNING);

 

but this is returning

Use of undefined constant E_TEST_WARNING - assumed 'E_TEST_WARNING'

 

any ideas?

I told you: you can NOT use custom error constants with built-in functions. You can only replicate this behavior by using your own defined functions:

 

function my_trigger_error($errstr, $errno = MY_ERR_NOTICE) {
    if (MY_ERR_NOTICE === $errno) {
        echo 'something';
        exit(0);
    }
}

//in your code somewhere:
my_trigger_error('BooBoo');

according to this I can

Ok if you don't believe me, the PHP manual says:

 

The designated error type for this error. It only works with the E_USER family of constants, and will default to E_USER_NOTICE.
