Great to hear that FirePHP has inspired this solution.

There is another tool similar to the one described in this post at: http://www.appelsiini.net/~tuupola/312/debugging-php-with-firebug

One challenge with both these solutions is that the server response must contain the JavaScript code to insert the messages into the Firebug Console.

FirePHP addresses this issue with the extended protocol and thus allows embedding of debug information in the server response even for binary image requests and pure AJAX JSON or XML calls where the response may not contain the extra JavaScript code.

FirePHP will support inserting messages into the Firebug console and/or a dedicated PHP console in the near future.

What a fantastic idea! Very nice job!

adding these two functions will allow you two use Buggy:dump($data,'title') to dump arrays and variables. For arrays it uses console.group() for formatting

function dump($data, $name='Data'){

if (is_array($data)){

echo "\n";

echo Buggy::dumpArray($data, $name);

echo "\n";

}else{

echo "console.info(\"[Buggy] - [dump] - "."\$".$name." = ".
addslashes($data)."\")\n";

}

}

function dumpArray($arr,$name,$sublevel=false) {

if($sublevel==false){

$output .= "console.group('Array \$".addslashes($name)."');\n";

}else{

$output .= "console.group('Array [".addslashes($name)."]');\n";

}

foreach($arr AS $key=>$val){

if (is_array($arr[$key])) {

$output .= Buggy::dumpArray($arr[$key],$key,true);

}else{

$output .= "console.log('[".
addslashes($key)."] => ".addslashes($val)."');\n";

}

}

$output .= "console.groupEnd();\n";

return $output;

}

I've modifed the dump array function so it works with objects or array, or horrible convoluted combinations thereof.

static function dumpArray($arr,$name,$sublevel=false) {
$output = "";
if($sublevel==false){
$output .= "console.group('Array \$".addslashes($name)."');\n";
}else{
$output .= "console.group('Array [".addslashes($name)."]');\n";
}
foreach($arr AS $key=>$val){
if (is_array($val) || is_object($val)) {
$output .= Buggy::dumpArray($val,$key,true);
}else{
$output .= "console.log('[".addslashes($key)."] => ".addslashes($val)."');\n";
}
}
$output .= "console.groupEnd();\n";
return $output;
}

Just something concerning this exemple's OOP :
in Buggy class, why do you use a global $Buggy variable ?
$Buggy belongs to Buggy class so it should be available for any method without specifing its accessibiliy.
If you want this variable to be reachable from any method, make it an object member.

example for object member :

class Buggy {
private $Buggy = array();
}

function SetMicroTime($module)
{
$this->Buggy[$module] = Buggy::getmicrotime();
}
}

example for class member :

class Buggy {
private static $Buggy = array();
}

function SetMicroTime($module)
{
self::Buggy[$module] = Buggy::getmicrotime();
}
}
