This post is part of the PHP Snippets series where I will be covering the basics of developing in PHP.
Almost everything you write in PHP ill have an output to the user; the simplest way of doing this is to use the in-built echo function (which you can use with or without parentheses).
The below example is a simple echo to output one line of text:
echo 'Hello world!';
You can output multiple lines of text, which you would do with multiple echo function calls:
echo 'Hello world!<br />';
echo 'This is a simple PHP example.';
Notice though, there is a HTML break line tag <br /> included at the end of the first line; if this wasn’t present, then both lines would be output on the same row.
