Arithmetic
php is capable of doing basic arithmetic, take the following for example using "echo"
<?php echo 17 * 123; ?> Outputs: 2091
Operators

- joins strings together
<?php echo "Hello," . " " . "world" . "!"; ?> ---- Outputs: Hello, world!
Each string above is defined between double quotes. The "dots" are between them and combine them together to form 1 long string.
