We summarized our experience on setting up WordPress on LEMP Ubuntu 18.04. We use Digital Ocean as our virtual private server. It comes with PHP7.2, FPM, and Certbot pre-installed. Nice isn’t it!
- Enable SSH to accept outside root connection. Open /etc/ssh/sshd_config, find PermitRootLogin and PasswordAuthentication lines. Set it to yes, and restart sshd by executing sudo service ssh restart.
- Install NGINX on Ubuntu first. The point is the NGINX must be allowed by the Uncomplicated Firewall (UFW) first.
- Install WordPress. Here is the shortlist: Create database, grant user, setting up NGINX, create configuration file for your website inside sites-available, setting up wp-config.php, restart FPM and restart NGINX.
- Install SSL. LEMP Ubuntu 18.04 on Digital Ocean comes with Certbot pre-installed. Just type ‘certbot’ in the command line.
- BONUS. Setting up HTTP2. This can speed up the website up to 2x.
By the way, there is question which is better upgrading from Ubuntu 14.04 to Ubuntu 18.04 to enable PHP7 for WordPress or start from fresh droplet or VPS account? The answer is better to start from the fresh one.
Upgrading from 14.04 to Ubuntu 18.04 will require you to upgrade to Ubuntu 16.04 first, in the meantime your server will be down and you’ll be firefighting the error. We don’t recommend upgrading your system. Start from a fresh droplet is easier and safer. Trust us.
I was overwhelmed by Mime-Type while I was working for a project. The problem is I don’t know how to retrieve the mime-type from a file, particularly file from another host. This url is the one I want t check its mime-type. Why do I have to check it? Because it doesn’t have proper extension for an image. Look how it shows ‘?v=1423061058’ as its extension. What is it!!!??

I’ve practiced about how to match USA telephone number format in different format using preg_match() function. The first time I found the exercise is in the Learning PHP 5 by David Sklar. In B8 exercise we have to write PHP script: regular expression that flexibly matches a U.S. phone number whether or not it has parentheses around the area code and has its parts separated by spaces, hyphens, or periods.
Of course, there is the answer for this exercise. But, when I tried, It didn’t smoothly solve the problem. The script wasn’t able to filter double parentheses like “((“, “))”, “(( )”, or “( ))”. So, I have a will to fix it and here the fixed script.

You may want to create editable data using PHP and HTML. You want to take your date type value to your <select> HTML tag. It is not difficult, but yes we need to be patient to code it.
First, you should call a query to your MySQL such as:
$sqlquery=mysql_query("select * from income where transaction_id='".$_GET['transaction']."'") or die(mysql_error());
$row = mysql_fetch_array($sqlquery);
Second, you have to set the type of your date in your table to DATE type. Don’t set it to VARCHAR or INTEGER. Let your MySQL database rules what it’s programmed to be. You just need to explode, separate, and put it into different <select> tag, as follow:

Storing a date from <select> HTML tag to MySQL database is not that easy. I spent three hours to find out how. First time I tried to, I was thinking that my script was not effective. But, after reading some tutorial I found my own way to do it. Here it is.
Put this script at the top of your PHP file because it needs to store data first and then execute the script after.
mysql_query("insert into income values('','".$thedate."')");

I found this site when I search the way to install Apache as webserver and PHP5 on my Ubuntu 10.10.
sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart
One said that you don’t need to run
sudo apt-get install libapache2-mod-php5 command because it is done with
sudo apt-getinstall apache2.
