如何调试php《转》

一个好的代码调试器可以让你在解决问题的时候事半功倍，因为代码调试器可以设置断点，可以逐行逐行代码进行跟踪，可以查看变量的值等等优点。每一种开发语言都有很好的代码调试器，PHP也不例外，Xdebug、Zend Debugger等都是十分好的php调试工具，本文将为您展示如何用eclipse+pdt+xdebug来调试php网站。

1.工具准备

eclipse，地球上的软件开发人员都知道能用它来开发java项目，其实还可以用它来开发php网站，点击这里下载集成了pdt的eclipse版本。选择适用于您的操作系统的进行下载。

php+apache，这两种工具只需要安装集apache、php、mysql、phpMyAdmin等于一身的xampp即可，如果您不知道如何安装和使用xampp，请阅读《如何安装xampp》和《如何安装部署php网站》。

Xdebug，如果您使用的是xampp，那么你无须下载xdebug，因为它已经集成了，你只需要在xampp的php.ini文件开启xdebug就行了。如果您没有使用xampp，那么你一定要选择合适您php版本的xdebug，否则会集成不成功的，如何知道要下载什么版本的xdebug？首先先创建一个php文件，里面的代码为，然后部署到php下运行，查看php的相关信息，把所有信息复制到xdebug官方的分析工具页面进行分析，它会给出您的php对应的分析结果，提示您下载对应版本的xdebug。

2.配置eclipse pdt

下载eclipse for php developers后，解压就可以使用了，打开后eclipse工具后就可以配置php和xdebug的相关信息了。

3.配置php，集成xdebug

如果您没有安装xampp，那么您就需要先下载你与您安装的php版本对应的xdebug，具体做法在第一点工具准备中已经说明，如果您已经安装了xampp，那么恭喜您，你只需要开启xdebug就行，具体做法就是打开php.ini，然后搜索Xdebug，找到后把zend_extension前的;去掉，把=号右面的路径改为”D:\xampp\php\ext\php_xdebug.dll”，(注：路径要修改为您自己安装的目录)，然后把以下几个选项前的;也去掉，并把=号右面的值改与下面的一致

xdebug.remote_enable=On

xdebug.remote_host=”localhost”，注：这里的localhost改为你的服务器对应的IP

xdebug.remote_port=9000

xdebug.remote_handler=”dbgp”

4.配置apache

通过配置apache服务器可以实现将访问路径映射到你本地的php网站程序目录，如果您安装了xampp，那么只需要修改apache\conf\extra目录下的httpd-xampp.conf文件，在标签内增加以下的代码：

Alias /phpip “D:/phpworkspace/HelloWorld/”

Options Indexes FollowSymLinks Includes ExecCGI

AllowOverride all Order allow,deny

Allow from all

其中，/phpip改为您想在浏览器中输入访问到项目的名称，D:/phpworkspace/HelloWorld/改为您程序对应的目录。

5.设置断点并调试

在eclipse中设置php调试断点，然后在浏览器中输入“http://servername/phpname/调试的文件”进行访问，servername是您的服务器的地址，phpname是您在apache中设置的php项目名。eclipse会提示是否打开调试控制面板，如下图：

接着可以逐行代码进行调试

在Debug output面板还可以查看网页浏览输出

到此，你已经学会如何调试php，赶快试试吧。

How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

What are the characteristics of do-while loops in PHP?May 15, 2025 pm 08:57 PM

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

How to hash strings in PHP?May 15, 2025 pm 08:54 PM

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

How to implement array sliding window in PHP?May 15, 2025 pm 08:51 PM

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

How to use the __clone method in PHP?May 15, 2025 pm 08:48 PM

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

How to use goto statements in PHP?May 15, 2025 pm 08:45 PM

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements. Overall, goto should be used with caution and best practices are followed to ensure the readability and maintainability of the code.

How to implement data statistics in PHP?May 15, 2025 pm 08:42 PM

In PHP, data statistics can be achieved by using built-in functions, custom functions, and third-party libraries. 1) Use built-in functions such as array_sum() and count() to perform basic statistics. 2) Write custom functions to calculate complex statistics such as medians. 3) Use the PHP-ML library to perform advanced statistical analysis. Through these methods, data statistics can be performed efficiently.

How to use anonymous functions in PHP?May 15, 2025 pm 08:39 PM

Yes, anonymous functions in PHP refer to functions without names. They can be passed as parameters to other functions and as return values of functions, making the code more flexible and efficient. When using anonymous functions, you need to pay attention to scope and performance issues.

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),
