php pdo_mysql not installed problem solution_PHP tutorial

When pdo_mysql is not installed, it will prompt that pdo_mysql must be supported. Please check whether the pdo_mysql module is loaded correctly. The installation method is very simple. Let me take a look.

Solution:

1. Modify the local php.ini configuration, taking the php.ini under Win as an example, find

;extension=php_pdo_mysql.dll

;extension=php_pdo.dll

Remove the preceding semicolon ";"

2. Restart the apache service.

May encounter problems

When establishing the Apache + Php + mysql + Zend environment, I encountered a problem. Using pdo_mysql.dll will report an error and IE will make an error. It turns out that just copy libmysql.dll to the apache directory.

Unzip the downloaded php-5.2-win32-VC6-x86-latest.zip and extract the libmysql.dll extension library. Copy it to the xamppapachebin and xamppphp directories to overwrite the original files. Restart apache

When using the php_pdo_mysql.dll extension library to connect to the database, I found that the IE page suddenly made an error and automatically closed
