What if php7 can't find the pdo extension?

Pdo error could not find driver solution in php7.1:

Record your mistakes.

I.

1. The reason is that there is no pdo extension

2. Solution: open php.ini and remove the semicolon (;) before the following two lines of code. As follows

Extension=php_pdo_firebird.dllextension=php_pdo_mysql.dll

Second, but when I run the pdo link, I still report this error. In the end, I found that there was something wrong with my pdo link string, which led to the failure to connect. The reason is that the function of single quotation marks and double quotation marks is not understood, the variables under single quotation marks will not be parsed by php, and the variables under double quotation marks and without symbols will be parsed by php.

Solutions that cannot be enabled by PHP7 PDO_MYSQL extension under windows:

The first step is to make sure that you have removed the ";" in front of extension=php_pdo_mysql.dll in php.ini.

The second step is to make sure that extension_dir = "D:/php/ext" D:/php is added to php.ini as your php path, and that there is a php_pdo_mysql.dll in the ext folder

If there's nothing wrong with it, there's something wrong with your apache configuration file.

Third, add the PHP path PHPIniDir "D:/php" to the apache configuration file httpd.conf

All right, restart apache, refresh and you'll see pdo_mysql.
