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

extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll

2. But when I run the pdo link, I still get this error. Finally, I found that there was a problem with my pdo link string, which made it impossible to connect. The reason is that the functions of single quotes and double quotes are not clear. PHP will not parse variables under single quotes, but PHP will parse variables under double quotes and without symbols.
