The echo command provides you with a way to output your string variables. It is a vital part of the PHP language mainly based on it use for outputing error messages as well as outputing success messages. By the end of this tutorial you should be able to integrate this into a project.

First off, you can use a string variable or use quotes (single and double) to display your echo. Below we have used both:

<?php $string = 'test 1'; echo $string; echo 'test 2'; ?>

Outputs the following: test 1 test 2

One major issue with the echo command is people typically output HTML with it. Adding HTML is actualy a great use of this tool but most people run into problems with certain codes.

When using codes like for instance <font face="tahoma"> in echo ""; they run into an error because they are using double quotes. The best way to fix this would be using a "\" or simple using the opposite (i.e: single and double).

If you are writing something in email for instance and have a long amount of text that needs paragraph spacing you can use a period. Look below:

<?php $string = "test 1" . "\r\n\n" . "test 2" . "\r\n" . "test3"; echo $string; ?>

This will ensure you receive your spaces without creating a problem with the quotes.
