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);

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
