使用xampp和xdebug，加上eclipse-php對程式進行調試

由於使用了xampp整合的環境，就直接使用預設的php.ini進行設定，昨天發現了xampp的獨特之處之外，比如說它把虛擬機器主機的配置

httpd-vhosts.conf與httpd.conf進行區分，這樣在httpd.conf中就可以只需要使用

<Directory "E:\www\trunk\admin">
Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>

配置了apache伺服器對部分檔案目錄的訪問情況，然後在httpd-vhosts.conf中添加對該檔案目錄對應的url地址：

<VirtualHost *:80>
DocumentRoot "E:\www\trunk\admin"
ServerName dev.admin.local
Alias /scripts "E:\www\trunk\common\javascripts"
Alias /files "E:\www\trunk\files"
</VirtualHost>

使用者就可以通過dev.admin.local訪問這個目錄了。

很多時候安裝xdebug會出現異常，比如提示

 

這個時候對xdebug進行了一定的配置，同時在

就可使用xdebug了，不過這裡尤其要注意的是，在xampp的php.ini設定檔中，有很多預設的值，需要使用者進行調整，比如其中就有了預設的

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"

; xdebug.remote_enable
; Type: boolean, Default value: 0
; This switch controls whether Xdebug should try to contact a debug client which is listening on the
; host and port as set with the settings xdebug.remote_host and xdebug.remote_port. If a connection
; can not be established the script will just continue as if this setting was Off.
xdebug.remote_enable = true


; xdebug.remote_handler
; Type: string, Default value: dbgp
; Can be either 'php3' which selects the old PHP 3 style debugger output, 'gdb' which enables the GDB
; like debugger interface or 'dbgp' - the brand new debugger protocol. The DBGp protocol is more
; widely supported by clients. See more information in the introduction for Remote Debugging.
xdebug.remote_handler = "dbgp"


; xdebug.remote_host
; Type: string, Default value: localhost
; Selects the host where the debug client is running, you can either use a host name or an IP
; address.
xdebug.remote_host = "localhost"


; xdebug.remote_log
; Type: string, Default value: none
; If set to a value, it is used as filename to a file to which all remote debugger communications are
; logged. The file is always opened in append-mode, and will therefore not be overwritten by default.
; There is no concurrency protection available.
xdebug.remote_log = "none"


; xdebug.remote_mode
; Type: string, Default value: req
;
; Selects when a debug connection is initiated. This setting can have two different values:
;
; req
;     Xdebug will try to connect to the debug client as soon as the script starts.
; jit
;     Xdebug will only try to connect to the debug client as soon as an error condition occurs.
;xdebug.remote_mode = "req"


; xdebug.remote_port
; Type: integer, Default value: 9000
; The port to which Xdebug tries to connect on the remote host. Port 9000 is the default for both the
; client and the bundled debugclient. As many clients use this port number, it is best to leave this
; setting unchanged.
xdebug.remote_port = 9000

對於前面使用;進行注釋的行，需要取消注釋，然後使得伺服器能夠正常的使用PHP。為了瞭解xdebug的真正功能，可以參考下面的英文文章，

正如我以前在調試代碼的時候，總是喜歡使用print_r();exit();這樣有個不好的地方在於，如果你線上上進行修改，這樣使用xdebug，就很容易

出現外界使用者在訪問的時候，有自己的調試代碼。而我通過xdebug來進行處理的時候，就避免了這個問題。

調試的效果圖如下：

如果不會，可以參考我上次談到的關於Zend studio的Firefox瀏覽器外掛程式。
