Handle fatal errors in PHP using register_shutdown_function()

Question

According to the comment on this answer it is possible to catch Fatal Errors through a shutdown function which cannot be caught using set_error_handler().

Answer 1

I use "ob_start" for this.

function fatal_error_handler($buffer) {
    if (preg_match("|(Fatal error:)(.+)|", $buffer, $regs) ) {
        //Your code
    }
    return $buffer;
}
ob_start("fatal_error_handler");
