PHP Console：https://github.com/barbushin/php-console#php-console-server-library
功能介绍
PHP Console工具和FirePHP功能相似，提供以下功能：
Handle PHP errors, dump variables, execute PHP code remotely in Google Chrome
Demo
首先在Chrome中安装PHP Console插件:
https://chrome.google.com/webstore/detail/php-console/nfhmhhlpfleoednkpnnnkolmclajemef
其次在PHP代码中引入PHP Console库，然后调用输出相应调试信息：
如下例index2.php：
|
1

<?php require_once(__DIR__ . '/../src/PhpConsole/__autoload.php');
// Call debug from PhpConsole\Handler$handler = PhpConsole\Handler::getInstance();
$handler->start();
$handler->debug('called from handler debug', 'some.three.tags');
$array = array(
'test' => 1,
'test2' => 1,
'key' => array(
1, 2, 3, 4,
),
);$handler->debug($array, 'test.wiki.wade.zhan');
|
输出调试信息到控制台，如下图：
原理介绍
PHP Console工具通过将调试信息输出到http响应头PHP-Console，然后PHP Console插件分析响应头PHP-Console字符串输出相应调试信息。
附录
PHP Console提供了通过密码来保护调试信息的功能，如下例，在服务器端设置密码：

<?php require_once(__DIR__ . '/../src/PhpConsole/__autoload.php');
$password = 'test';
$connector = PhpConsole\Connector::getInstance();
$connector->setPassword($password);
// Call debug from PhpConsole\Handler$handler = PhpConsole\Handler::getInstance();
$handler->start();
$handler->debug('called from handler debug', 'some.three.tags');
$array = array(
'test' => 1,
'test2' => 1,
'key' => array(
1, 2, 3, 4,
),
);$handler->debug($array, 'test.wiki.wade.zhan');
|
此时可以看到只有当客户端输入正确的密码：
此时响应头部才会输出相应的调试信息：
