How to display content using PHP echo

Displaying content with PHP is pretty easy. You simple use the built-in PHP echo function.

How to display content with PHP echo:


1. Create a test PHP page on your web server, for this example we will use echo.php.

2. Add the following code to the echo.php page.

echo "Hello World!";

3. Open the page in your web browser

http://Your-Domain/echo.php

That's it. Pretty easy, huh. Well this way is easy but it can get a bit complex when you want to display dynamic content or build the entire page in PHP, echoing the html code as well as the content.

If you wanted to display a variable that you got from a database query or something like that you could simply do:

echo $MyVar;

Now if you wanted to output the page html code you may need to use sign quotes to enclose the data you are going to echo out. This is because the html code may use double quotes and that will cause the echo statement to error out.

This would error out because of the double quotes in the html code:

echo "<a href="echo.php">Test Echo Page</a>";

This would work:

echo '<a href="echo.php">Test Echo Page</a>';

Other ways you may want to display the content is with some html code and php variables. To do this you need to break the echo statement up by using the open and close quotes between the html and the php code.

For example:

echo '<a href="'.$URL.'">Test Echo Page</a>';

The above example will echo out the html code and the dynamic page assigned to the $URL variable.
