如何處理 PHP 5.2 中的致命 PHP 錯誤 (E_ERROR)？

register_shutdown_function("fatal_handler");

function fatal_handler() {
    $errfile = "unknown file";
    $errstr = "shutdown";
    $errno = E_CORE_ERROR;
    $errline = 0;

    $error = error_get_last();

    if ($error !== NULL) {
        $errno = $error["type"];
        $errfile = $error["file"];
        $errline = $error["line"];
        $errstr = $error["message"];

        error_mail(format_error($errno, $errstr, $errfile, $errline));
    }
}

function format_error($errno, $errstr, $errfile, $errline) {
    $trace = print_r(debug_backtrace(false), true);

    $content = "
    <table>
        <thead><th>Item</th><th>Description</th></thead>
        <tbody>
            <tr>
                <th>Error</th>
                <td><pre class="brush:php;toolbar:false">$errstr

$errno
