Strings in PHP7

If you have been following along in our lessons we have used several strings. A string in PHP can be encapsulated with single or double quotes. A PHP string is made up of several letters, numbers and even code like HTML, javaScript and CSS. Here is an example of a string.

<?php $var="I Love PHP7" var_dump($var);?>

This is the result. When you use var_dump it returns the value and also the number of characters that are in a string.

string(11) “I love PHP7”

Using Strings With Code in PHP7

<?php $string='
<h3>PHP7 Is Awesome</h3>';
echo $string; ?>
