Pretty print stack trace in PHP

stacktrace.php

function stackTrace() {
    $stack = debug_backtrace();
    $output = 'Stack trace:' . PHP_EOL;

    $stackLen = count($stack);
    for ($i = 1; $i < $stackLen; $i++) {
        $entry = $stack[$i];

        $func = $entry['function'] . '(';
        $argsLen = count($entry['args']);
        for ($j = 0; $j < $argsLen; $j++) {
            $func .= $entry['args'][$j];
            if ($j < $argsLen - 1) $func .= ', ';
        }
        $func .= ')';

        $output .= '#' . ($i - 1) . ' ' . $entry['file'] . ':' . $entry['line'] . ' - ' . $func . PHP_EOL;
    }

    return $output;
}

Thank you, just what I needed!

NOTE

If the function arguments cannot be converted to a string, you'll receive an error in line 12.
To circumvent this problem I just exported that variable:
LINE 12: $func .= var_export($entry['args'][$j],true);

If your code throws an exception at or near a database connection it's probably best to strip out and/or not print out any arguments else you may leak sensitive database credentials in your logs
