PHP Debug Bar

2020 年 10 月 8 日1420

Install the debug bar using Composer:

{




  "require": {




    "maximebf/debugbar": "1.*"




  }




}

$ php composer.phar install

The DebugBar has two parts: the main DebugBar object with data collectors and the renderer.

Data collectors are objects collecting a specific set of data. To makes things easy,

the StandardDebugBar has all the built-in collectors activated.

<?php




use DebugBar\StandardDebugBar;









$debugbar = new StandardDebugBar();




$debugbarRenderer = $debugbar->getJavascriptRenderer();









$debugbar["messages"]->addMessage("hello world!");




?>




<html>




<head>




    <?php echo $debugbarRenderer->renderHead() ?>




</head>




<body>




    ...




    <?php echo $debugbarRenderer->render() ?>




</body>




</html>
