Is there a Pretty Print Stack Dump?

Question

Let\'s face it, debug_backtrace() output is not very pretty. Did anyone code a wrapper?

And what\'s your favourite pretty var_dump() (which is

Answer 1

Gonna add mine to the rest of the answers here.

If you have bootstrap and jquery installed, it's even more useful and compact, but its not neccessary.

function prettyPrintBackTrace() {
    $backtrace = "\n<b><u>Full Backtrace</u></b>\n<script>function toggleBackTraceTwirl(self) {\$('span', self).toggleClass('glyphicon-menu-up glyphicon-menu-down');}</script>";
    foreach (debug_backtrace() as $key => $trace) {
        if(($trace['function'] ==__FUNCTION__) || ($trace['function'] == "fail")) {continue;}
        $class = (array_key_exists('class', $trace) ? "class <u>({$trace['class']})</u>" : false);
        $exp = explode("/",$trace['file']);
        $exp[count($exp)-1] = "<b>" . end($exp) . "</b>";;
        $filename = implode("/",array_splice($exp, -4));    
        $backtrace .=  "/{$filename}:{$trace['line']}, ";
        if((isset($trace['args'])) && (is_array($trace['args']))) {


            if( (is_string($trace['args'][0])) && (substr($trace['args'][0],-4) == ".php") && (count($trace['args'] == 1)) ) {
                // It was most likely a php include of some sort.
                $exp = explode("/",$trace['args'][0]);
                $filename = implode("/",array_splice($exp, -2));
                $backtrace .= "function <i>{$trace['function']}(<b>{$filename}</b>)</i>\n";
            } else { 
                // Finish the line and move on.
                $backtrace .= "function <i>{$trace['function']}()</i>&nbsp;<a href='#' data-target='#backtraceparameters{$key}' onClick='toggleBackTraceTwirl(this)' data-toggle='collapse'><span class='glyphicon glyphicon-menu-down'></span></a>\n";
                $backtrace .=  "<div id='backtraceparameters{$key}' class='collapse'>";
                $args = array();
                foreach($trace['args'] as $key => $val) {
                    if($val) $args[(!is_numeric($key) ? "key" : false)] = $val;
                }
                foreach($args as $count =>  $a) {
                    $backtrace .= ($count != (count($args) -1) ? "&boxvr;" : "&boxur;");
                    $value = $a;
                    if($a === true) $value = "<i>true</i>";
                    if($a === false) $value = "<i>f alse</i>";
                    $backtrace .= "&boxh; ".(!is_numeric($count) ? $count." " : false).var_export($value,1)."\n";
                }
                $backtrace .=  "</div>";
            }
        }
    }
    return $backtrace;
}

I hope that helps someone. I've tried to make it as compact as possible.

Answer 2

Here is my pretty print wrapper that is intended for non-browser output, ie error logs or the console:

function stackTrace() {
    $stack = debug_backtrace();
    $output = '';

    $stackLen = count($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 .= $entry['file'] . ':' . $entry['line'] . ' - ' . $func . PHP_EOL;
    }
    return $output;
}
