Xdebug is an open source PHP debugger (a debug tool) that is powerful enough to track, debug, and analyze the PHP program's health. Xdebug now the latest version is xdebug 2.1.0, download page is http://xdebug.org/download.php, note that the download link in the page has multiple (the following figure), according to their own number of computers and PHP version to choose, Figuring out the version of your PHP and whether it's thread-safe (viewed through the Phpinfo function), the PHP5.3 version of the user also needs to know which compiler compiled the PHP to decide to download the VC6 or VC9 version. For example, my PHP version is 5.2.x and thread safe, so choose 5.2 VC6 (bit) download, the filename is php_xdebug-2.1.0-5.2-vc6.dll:

2. Eclipse

Eclipse is an open source, java-based, extensible development platform. For its part, it is just a framework and a set of services for building the development environment through plug-in components. Use it, you can bring a lot of convenience for our PHP development, software can be downloaded on its website.

The installation of Eclipse will not be said. Xdebug installation method is not difficult, first of all downloaded to the file renamed Php_xdebug.dll placed in the ext/directory of PHP, and then modify the php.ini file, add the following lines at the end of the file:

[Xdebug]
; Specify the location of the xdebug extension file (path Please adjust according to your situation)
Zend_extension_ts = "F:/library/php_xdebug-2.1.0-5.2-vc6.dll"

First select PHP-> Debug (below) on the left side of the window-> Preferences window, and select Xdebug in the PHP debugger to the right of the windows, which has a configure link to the right of this option. Click here to set the Xdebug, make sure that the port number that Xdebug uses is the same as specified in php.ini file (typically 9000), the following two items are set up Web server and PHP interpreter, and then the following break at Line indicates that the start of debugging is disconnected at row 1th:

Set up after the program can be debugged, click on the tool bug-> Debug AS, here you can choose to Web page form or PHP script in the form of debugging (as shown below):

If it goes well, the current workspace view will switch to PHP debug, and then the program will be disconnected on line 1th, and then you can do a single step (the following figure), debugging methods do not say more, their own groping, in short, is very convenient:
