Question

mysqli_connect not working for me

Hi,

I created a new droplet but same issue has occurred with my original droplet. Created lamp phpmyadmin sshless install.

connected to my page and changed the default index.html to index.php

Found my mySQL admin user + password and wrote the following script:

<?php $hostname = “p:127.0.0.1:3306”; $username = “admin”; $password = “xxxxxxxx”; $conn = mysqli_connect($hostname, $username, $password) OR DIE (“Unable to connect to database!”); ?>

and I am unable to connect to mySQL using mysqli_connect.

Tried with app and root as well , same results. with a different droplet I created a new user. New user managed to get connected using mysql workbench but still no results mysqli_connect.

This is the last hurdle for me to move all my stuff to Digital Ocean. I need to be able to connect my code to mt database.

What am I doing wrong?

Hi friend,

the p is for a persistent connection. One could remove it. BTW I found what my problem was. For a mySQL user to be able to connect with php mysqli_connect, one must grant user all privelages and then bind the user with the following coammnds in server terminal:

GRANT ALL PRIVILEGES ON . TO ‘newuser’@‘localhost’; FLUSH PRIVILEGES; #bind-address = 127.0.0.1

Hey friend,

Great question! I’m not an expert on PHP but I tend to be able to troubleshoot it reasonably at times. I’m confused about one line in the code:

$hostname = "p:127.0.0.1:3306";

Particularly the “p:” part. Does this work if you remove that? I’m just not seeing where that fits in from the documentation:
