PHP Code:

<?php
$myString = "Hello!";
echo $myString;
echo "<h5>I love using PHP!</h5>";

?>

In the above example we output "Hello!" without a hitch. The text we are outputting is being sent to the user in the form of a web page, so it is important that we use proper HTML syntax!

In our second echo statement we use echo to write a valid Header 5 HTML statement. To do this we simply put the <h5> at the beginning of the string and closed it at the end of the string. Just because you're using PHP to make web pages does not mean you can forget about HTML syntax!

Careful When Echoing Quotes!

It is pretty cool that you can output HTML with PHP. However, you must be careful when using HTML code or any other string that includes quotes! The echo function uses quotes to define the beginning and end of the string, so you must use one of the following tactics if your string contains quotations:

Don't use quotes inside your string

Escape your quotes that are within the string with a slash. To escape a quote just place a slash directly before the quotation mark, i.e. \"

Use single quotes (apostrophes) for quotes inside your string.

See our example below for the right and wrong use of the echo function:

If you want to output a string that includes quotations, either use an apostrophe ( ' ) or escape the quotations by placing a slash in front of it ( \" ). The slash will tell PHP that you want the quotation to be used within the string and NOT to be used to end echo's string.

Echoing Variables

Echoing variables is very easy. The PHP developers put in some extra work to make the common task of echoing all variables nearly foolproof! No quotations are required, even if the variable does not hold a string. Below is the correct format for echoing a variable.

Echoing Variables and Text Strings

You can also combine text strings and variables. By doing such a conjunction you save yourself from having to do a large number of echo statements. Variables and text strings are joined together with a period( . ). The example below shows how to do such a combination.

This combination can be done multiple times, as the example shows. This method of joining two or more strings together is called concatenation.
