PHP cannot connect to PostgreSQL

I recently met a customer who was using a PostgreSQL database. I had never used this database before. So I am considered a newbie, and I don’t have too much say. I just record the questions here and share them with everyone. I hope friends I meet later can refer to them. Without further ado, read below

This error occurs when using php to connect to pgsql. To summarize, the solution is as follows:

1. In the php configuration file php.ini, remove extension=php_pdo_pgsql.dll and extension=php_pgsql.dll Comma

2. If there are still problems after the above configuration is changed, it may be a problem with the php version. The environment I use is wamp and phpstudy are both 5.3. The problem is solved after upgrading to 5.6 (I have not tried the 5.4 and 5.5 versions. There are You can try it yourself if you are interested)
