将php的debug信息与firefox的控制台挂钩



class PHPDebug {

function __construct() {
if (!defined("LOG")) define("LOG",1);
if (!defined("INFO")) define("INFO",2);
if (!defined("WARN")) define("WARN",3);
if (!defined("ERROR")) define("ERROR",4);

define("NL","\r\n");
echo &＃39;&＃39;;
/// end of IE
}

function debug($name, $var &＃61; null, $type &＃61; LOG) {
echo &＃39;&＃39;.NL;
}
}




使用起来也很方便,例子如下:



// include and instantiate the class
require_once("PHPDebug.php");
$debug &＃61; new PHPDebug();

// simple message to console
$debug->debug("A very simple message");

// vaiable to console
$x &＃61; 3;
$y &＃61; 5;
$z &＃61; $x/$y;
$debug->debug("Variable Z: ", $z);

// a warnign
$debug->debug("A simple Warning", null, WARN);

// info
$debug->debug("A simple Info message", null, INFO);

// An error
$debug->debug("A simple error messsage", null, ERROR);

// Array in console
$fruits &＃61; array("banana", "apple", "strawberry", "pineaple");
$fruits &＃61; array_reverse($fruits);
$debug->debug("Fruits array", $fruits);

// object to console
$book &＃61; new stdClass;
$book->title &＃61; "Harry Potter and the Prisoner of Azkaban";
$book->author &＃61; "J. K. Rowling";
$book->publisher &＃61; "Arthur A. Levine Books";
$book->amazon_link &＃61; "http://www.amazon.com/dp/0439136369/";
$debug->debug("Object", $book);




这样,就可以将各种警告或错误,分门别类地显示在浏览器的控制台中了
