I've just made a database on mysql on my server. I want to connect to this via my website using php. This is the contents of my connections file:
I know what the username/passwords are, and I know the IP address of the server. What I'm just wondering is how do I know which port to use? Pieces yamaha 125 dtlc 1989.

If your MySQL server runs on default settings, you don't need to specify that.
Default MySQL port is 3306.

PHP 5 and later can work with a MySQL database using: MySQLi extension. With MySQLi, you will need to rewrite the entire code - queries included.

For windows, If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --
It will give you the port number on which MySQL is running.
if you want to have your port as a variable, you can write php like this:
If you specify 'localhost' the client libs default to using the filesystem system socket on a Unix system - trying the mysql_default_socket value from php.ini (if set) then the my.cnf value.
If you connect using a different tool, try issuing the command 'show variables like '%socket%'
If you want to use a network port (which is a wee bit slower) then try specifying 127.0.0.1 or a physical interface asociated with the machine.
default port of mysql is 3306
default pot of sql server is 1433
This is a PDO-only visualization, as the mysql_*
library is deprecated.
Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306
always, then consider removing it from the uri, that is, remove the port=$port;
part.
If you often change ports, consider the above port usage for more maintainability having changes made to the $port
variable.
Some likely errors returned from above:
In the below error, we are at least getting closer, after changing our connect information:
After further changes, we are really close now, but not quite:

Inheritance In TypeScript, we can use common object-oriented patterns. One of the most fundamental patterns in class-based programming is being able to extend existing classes to create new ones using inheritance. Let’s take a look at an example: class Animal move (distanceInMeters: number = 0) console.log. An abstract class declaring any property should not enforce a subclass to implement a get or set method as what implementation is required? Again even a partially concrete use case would be very useful to understand what problem you are trying to solve and how you think abstract properties would help. Typescript get class properties.

I have also written step by step Tutorial for Restful Web Services in PHP Example – PHP + MySQL Best Practice. Today I’m going to connect login & Signup Webservices using Login & Signup HTML page. You can use any HTML page, I’m using This because it has a really beautiful design and has Form for both Login & Signup.
- File Structure
- Creating HTML page
- Connecting HTML page with Webservices
File Structure
We’ll use this folders & files structure inside our “app” folder for our Login & Signup page.
index.html
|
assets
├─── css
├────── style.css
api
├─── config/
├────── database.php – file used for connecting to the database.
├─── objects/
├────── user.php – contains properties and methods for “user” database queries.
├─── User/
├────── signup.php – file that will accept user data to be saved to the DB.
├────── login.php – file that will accept username & password and validate
as you can see that we have added pages and assets folders, pages folder will contain all HTML pages and assets folder is for CSS, JS, images etc.
Creating HTML page
as I stated that you can create your own design or you can use any other design, for this tutorial I’m using This template and I just modified it according to my Webservices.
inside your “app” folder, create a new file as “index.html” and paste this code there
Now go to the “assets” folder and create a new folder as “css” and create a new file there as “style.css” and paste this code there
![Source Source](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2017/03/hostinger-control-panel-create-mysql-databse.png)
Now you’ll see the page same as this
Connecting HTML page with Webservices
Download Login & Signup API from Github you can also create these API following my previous post, Restful Web Services in PHP Example – PHP + MySQL Best Practice
setup Database and paste “api” folder inside “app” folder.
all done, Now you can run your index.html through localhost.
