PHP性能测试工具xhprof的安装和使用
最近要做网站的性能对比,于是就找一款性能测试工作来玩玩,工具很多,但相比之前还是觉得xhprof的安装和使用相对来说简单点,数据分析也都还可以,下面就说说它的安装和使用。。。
下载xhprof和graphviz
xhprof的话,直接去php官网就可以下载,为了方便可以戳一下 这里
graphviz的话也要下载,主要是显示xhprof性能结果的图形报表,戳这里 这里
编译安装xhprof
cd xhprof-0.9.4/xhprof-0.9.4/extension/phpize./configuremakesudo make install
将生成的xhprof.so文件加到php.ini文件中,然后重启apache了
...#这里要使用相对路径加载的话首先要看一下extension_dir配置的路径,或者直接写上`.so`文件的绝对能够路径即可。。。extension=xhprof.so...sudo apachectl restart##测试扩展是否安装成功,有如下输出则okphp --ri xhprof ... xhprof xhprof => 0.9.2 CPU num => 4...
安装graphviz
cd graphviz-2.38.0/#后面参数是要确保安装了libphp才行哦【没安装的 brew install linpng 就可】./configure --with-png=yesmakesudo make install
测试一下了
在之前下载的xhprof文件夹里面,找到xhprof_html,xhprof_lib、sample三个文件夹,那这三个文件夹放到你可以访问到得地方去,然后通过连接先访问以下http://xxxx/sample/sample.php,在访问以下http://xxxx/xhprof_html/,就会看到有一条记录,点击后就可以看到分析结果页面,通过点击 View Full CallGraph链接到图形报表的页面。
如何使用
假设你现在要看看看自己做的一个网站的首页性能数据,那么你要找到这个网站的首页入口文件,在核心文件加载之前和之后分别加上xhprof的性能测试代码
#开启,具体参数说明可以查看官方文档xhprof_enable(XHPROF_FLAGS_NO_BUILTINS | XHPROF_FLAGS_CPU | XHPROF_FLAGS_MEMORY);#核心文件的执行...require 'index.php'...#关闭$xhprof_data = xhprof_disable();#这里的路径根据自己的站点来配置$XHPROF_ROOT = realpath(dirname(__FILE__) .'/');include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";$xhprof_runs = new XHProfRuns_Default();$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof");#这里打印出本次测试的id,方便到报表列表页面【http://xxxx/xhprof_html/】去通过对应的id找到对应的结果var_dump($run_id);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
