一:安装 安装方法一:编译安装 1、下载PHP的XDebug扩展,网址:http://xdebug.org/ # wget http://pecl.php.net/get/xdebug-2.1.2.tgz # tar -xzf xdebug-2.1.2.tgz # xdebug-2.1.2 # cd xdebug-2.1.2 # /usr/local/php/bin/phpize # ./configure --enable-

一:安装

安装方法一:编译安装

 

1、下载PHP的XDebug扩展,网址:http://xdebug.org/
# wget http://pecl.php.net/get/xdebug-2.1.2.tgz
# tar -xzf xdebug-2.1.2.tgz
# xdebug-2.1.2
# cd xdebug-2.1.2
# /usr/local/php/bin/phpize
# ./configure --enable-xdebug --with-php-config=/usr/local/php/bin/php-config
# make && make install

php扩展xdebug安装以及用kcachegrind系统分析

不需要自己拷贝xdebug.so了,下面可以省。
# cp modules/xdebug.so /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613

注:/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/不同的PHP版本路径不同,也不一定要放在该路径,可以在zend_extension_ts中自行指定xdebug.so所在位置。

================================================

安装方法二:自动安装

http://pecl.php.net/package/xdebug

 

#  /usr/local/php/bin/pecl install xdebug 

安装成功

windows下安装:

需要注意使用custom installation instructions. 将你的phpinfo生成的内容放进去测试 看看下载那个dll

===============================================

二:修改php配置模块

1.配置

修改php.ini,去除PHP加速模块,增加以下配置信息支持XDebug扩展

手动安装

[Xdebug]  
zend_extension_ts="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so" 

xdebug.profiler_enable=on 
xdebug.trace_output_dir="/tmp/xdebug" 
xdebug.profiler_output_dir="/tmp/xdebug" 


 

自动安装

[Xdebug]

extension=xdebug.so

xdebug.profiler_enable=on
xdebug.trace_output_dir="/tmp/xdebug"
xdebug.profiler_output_dir="tmp/xdebug"

 

Windows下配置 

 用phpinfo()查看php配置文件位置,增加:

extension=php_xdebug-2.2.0-5.3-vc9.dll

[Xdebug]

;开启自动跟踪
xdebug.auto_trace = On
;开启异常跟踪
xdebug.show_exception_trace = On
;开启远程调试自动启动
xdebug.remote_autostart = On
;开启远程调试
xdebug.remote_enable = On
;收集变量
xdebug.collect_vars = On
;收集返回值
xdebug.collect_return = On
;收集参数
xdebug.collect_params = On

xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000  

xdebug.profiler_enable=on
;xdebug.trace_output_name="%H.%s"
xdebug.trace_output_dir="E:\PHPnow\xdebug"
xdebug.profiler_output_dir="E:\PHPnow\xdebug"


 

------------------------------

2.权限

mkdir -p /tmp/xdebug
chmod 755 /tmp/xdebug
chown www:www /tmp/xdebug

-----------------------------

3.重启
/usr/local/apache/bin/apachectl  restart

 php扩展xdebug安装以及用kcachegrind系统分析

说明:如果phpinfo()没有打印这个信息说明没有配置正确!

------------------------------

4.停用

说明:如果不分析系统一定要记得关闭xdebug.profiler不然会生成许多文件

xdebug.profiler_enable=off

 ====================================

三:分析系统

1.访问你的网站

将首页上各种链接点击几遍,XDebug在/tmp/xdebug目录生成文件

 

2.使用图形分析工具wincachedgrind分析生成的文件

下载地址:http://sourceforge.net/projects/wincachegrind/files/

3.下载图形化工具kcachegrind在windows下的可执行版

下载地址http://sourceforge.net/projects/precompiledbin/files

 

用kcachegrind来看会更形象,注意需要修改从linux中执行的文件的php文件路径,这样就可以了sourcecode.

 更复杂的代码:

<?php define( 'BOOSTER', 5 );
    define( 'CAPSULE', 2 );
    define( 'MINUTE', 60 );
    define( 'STAGE', 3 );
    define( 'PRODUCTION', 1000 );
    
    class Part {
        function Part() {
            $this->build( MINUTE );
        }
        
        function build( $delay = 0 ) {
            if ( $delay  0 ) {
            }
        }
    }
    
    class Capsule extends Part {
        function Capsule() {
          parent::Part();
            $this->build( CAPSULE * MINUTE );
        }
    }
    
    class Booster extends Part {
        function Booster() {
          parent::Part();
            $this->build( BOOSTER * MINUTE );
        }
    }
    
    class Stage extends Part {
        function Stage() {
          parent::Part();
          $this->build( STAGE * MINUTE );
        }
    }
    
    class SpaceShip {
        var $booster;
        var $capsule; 
        var $stages;
        
        function SpaceShip( $numberStages = 3 ) {
            $this->booster = new Booster();
            $this->capsule = new Capsule();
            $this->stages = array();
            
            while ( $numberStages-- >= 0 ) {
                $stages[$numberStages] = new Stage();
            }
        }
    }
    
    $toys = array();
    $count = PRODUCTION;
    
    while ( $count-- >= 0  ) {
      $toys[] = new SpaceShip( 2 );
    }
?>

KCacheGrind windows 系統下的代替方案

  1. WinCacheGrind
  2. 可分析由xdebug產出的cachegrind.xxx檔,簡易版的kcachegrind。

  3. windows port of kcachegrind
  4. 由原linux的kcachegrind,重新編譯在windows上可執行版,功能與linux kcachegrind相同。

  5. Webgrind
  6. 網頁版的callgrind,搭配xdebug可做即時線上做php script profile。

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
