命令行PHP mysql_connect（）错误

问题描述

我正在运行php页面从命令行更新mysql db一旦php exec命令完成。

但是，我刚刚重新安装了我的服务器，现在脚本在命令行运行时返回以下错误：

 致命错误：调用未定义函数mysql_connect（）
  

脚本在浏览器中运行良好，这意味着mysql安装完成。 如何在命令行中启用PHP中的mysql？

非常感谢。

解决方案

首先，您可以使用

  php -m 
  

从命令行检查启用了哪些扩展。

如果mysql不在列表中，则意味着它未启用/加载 - 这可能是这种情况。

然后，您要使用

  php --ini 
  
 
 
 
以检查哪些 .ini 文件已由PHP读取。
 
 
 
 
 
一旦你找到了使用了 php.ini 的文件，编辑它，并添加如下：
 ;配置php MySQL模块
 extension = mysql.so 
  
加载 mysql 扩展。
 
 
 
 
 
根据您的发行版本，可能是。 ini 每个扩展程序文件（例如，Ubuntu就是这样）。
 
 
 
如果是这样，创建一个新的 .ini 文件（例如 mysql.ini ），我发布到该新文件。
 
I am running a php page form the command line to update a mysql db once a php exec command has completed. This has been working OK.
However, I have just reinstalled my server and now the script is returning the following error when I run it on the command line:
Fatal error: Call to undefined function mysql_connect()
The script runs fine in the browser which means mysql is installed OK. How do I enable mysql in PHP to be run from the command line?
Many thanks.
 解决方案 
First of all, you can use 
php -m
from the command-line, to check which extensions are enabled.
If mysql is not in the list, it means it's not enabled / loaded -- which is probably the case, here.

Then, you'll want to use 
php --ini
to check which .ini file(s) is/are read by PHP.

Once you've found out which php.ini file is used, you'll have to edit it, and add something like this :
; configuration for php MySQL module
extension=mysql.so
To load the mysql extension.

Depending on your distribution, the might be a .ini file per extension (Ubuntu does that, for instance).
If that's the case, you could also create a new .ini file (mysql.ini for instance) next to the other ones, and put the two lines I posted into that new file.
