Here is a function to cleanly output the debug_backtrace to the error_log



<?php

/*

 * Send the output from a backtrace to the error_log

 * @param string $message Optional message that will be sent the the error_log before the backtrace

 */

function log_trace($message = '') {

    $trace = debug_backtrace();

    if ($message) {

        error_log($message);

    }

    $caller = array_shift($trace);

    $function_name = $caller['function'];

    error_log(sprintf('%s: Called from %s:%s', $function_name, $caller['file'], $caller['line']));

    foreach ($trace as $entry_id => $entry) {

        $entry['file'] = $entry['file'] ? : '-';

        $entry['line'] = $entry['line'] ? : '-';

        if (empty($entry['class'])) {

            error_log(sprintf('%s %3s. %s() %s:%s', $function_name, $entry_id + 1, $entry['function'], $entry['file'], $entry['line']));

        } else {

            error_log(sprintf('%s %3s. %s->%s() %s:%s', $function_name, $entry_id + 1, $entry['class'], $entry['function'], $entry['file'], $entry['line']));

        }

    }

}
