Question

I’m using the code below for logging and sending error to my e-mail, but i don’t know why $content variable does not contain anything when i check my emails. Is this a scope mistake? or I’m doing something wrong?

ob_start();
set_error_handler('cs_handler', E_ALL);

//a lot includes and method calls here

function cs_handler($errno, $errstr, $errfile, $errline)
{
    $content = ob_get();
    mail(...., 'Error Happend: '.$content);
}

Answer 1

One issue is that you’ll need to call ob_start() again, after flushing the buffer, if you want multiple errors-per-page to work properly. Could this be the problem? Are you getting one email with content, followed by others without?

Another issue you might be having is that you’re calling mail() with 2 arguments, when it expects 3 (address, subject, content). You probably want something like:

mail('[e-mail]', 'Error Happened', $content);

Note that the following works as expected:

ob_start();
set_error_handler('cs_handler', E_ALL);

echo 'begun';

echo $arr['test']; // This throws a warning, handled by the function below

function cs_handler($errno, $errstr, $errfile, $errline)
{
    $content = ob_get_clean();
    mail('[e-mail]', 'Error Happened', $content);
}
