PLSQL到目前为止只有32位的程序，而大多数的桌面系统基本都是使用64位的Windows操作系统，在64位的Windows上，大多数情况下也是安

1、问题

PLSQL到目前为止只有32位的程序，而大多数的桌面系统基本都是使用64位的Windows操作系统，在64位的Windows上，大多数情况下也是安装64位的Oracle client程序，这种组合，导致plsql无法识别到ORACLE_HOME目录，读取不到tnsnames.ora文件中的连接串

2、解决方案

2.1 在Windows上配置ORACLE_HOME环境变量

右击“我的电脑”点击”属性“菜单，进入”系统属性“对话框，选择”高级“标签，点击“环境变量”，在用户变量框区域，新建一个名为‘ORACLE_HOME的变量名，根据自己的ORACLE实际安装目录填写其值，例如，笔者的环境的ORACLE_HOME的值为” C:\oracle\product\12.1.0\dbhome_1”

2.2 引用instantclient-basic-win32-10.2.0.5

将instantclient-basic-win32-10.2.0.5.zip文件解压，压缩后的文件，复制到PLSQL Developer安装目录的product目下，如C:\oracle\product\，最终instantclient的目录为C:\oracle\product\C:\oracle\product\instantclient-basic-win32-10.2.0.5\instantclient_10_2

instantclient-basic-win32-10.2.0.5.zip文件，笔者已上传到“系统性能优化专业群”群共享中供各位下载。

2.3 在PLSQL中配置ORACLE_HOME与OCI库

2.3.1 配置ORACLE_HOME

在PLSQL主菜单上点击Tools，选择Preferences子菜单，进入“首选页”对话框，在“连接”选项卡的右侧，找到“Oracle主目录名（自动检测为空）”，在该框中填写ORACLE的HOME目录名，如：“C:\oracle\product\12.1.0\dbhome_1”

2.3.2 配置OCI库

在PLSQL主菜单上点击Tools，，选择Preferences子菜单，进入“首选页”对话框，在“连接”选项卡的右侧，找到“OCI库（自动检测为空）”，在该框中填写oci.dll文件的绝对路径，如：“C:\oracle\product\instantclient-basic-win32-10.2.0.5\instantclient_10_2\oci.dll”

3、结果

上述四步配置完成后，重启PLSQL，就可以识别ORACLE_HOME，并能找到ORACLE客户端tnsnames.ora文件中的数据库连接串了。

MySQL: Adding a user through a PHP web interfaceMay 14, 2025 am 12:04 AM

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
