[英]Warning /Fatal error require(MDB2.php) after install PHP PEAR and MDB2
我已經在本地主機上成功安裝了PEAR和MDB2。 但是,當我試圖運行由MDB2給出的示例代碼中,我得到錯誤(附圖片)
安裝后還會多次重啟Wamp服務器。
錯誤和警告
警告:
require(MDB2.php)
未能打開流:在沒有這樣的文件或目錄E:\\wamp\\www\\pear_project\\examples\\example_php5.php
第8行致命錯誤:
require()
無法所需'MDB2.php'開口(include_path='.;C:\\php\\pear'
)在E:\\wamp\\www\\pear_project\\examples\\example_php5.php
第8行
在PEAR安裝過程中, go-pear默認修改了php.ini 。

只要對php.ini進行了更改,就應該重新啟動Web服務器,否則它們將不會生效。
您當前的配置正在查找: include_path='.;C:\\php\\pear'
但是,您的安裝目錄位於: E:\\wamp\\bin\\php\\php5.4.12\\pear
重新啟動wampp安裝后,它應該開始工作。
我已經解決了這個問題。 卸載舊的WAMP並刪除其余的WAMP文件夾。 然后重新安裝WAMP和PEAR。 使用PHP文件夾路徑修改環境變量。
E:\\ wamp \\ bin \\ apache \\ Apache2.4.4 \\ bin中還有另一個php.ini
使用相同的包含路徑修改php.ini

include_path=".;E:\wamp\bin\php\php5.4.12\pear"

安裝數據庫軟件包MDB2,
並重新啟動服務器。
