How can I echo in PHP? I am new to programming. I want to echo content to the frontend from a backend PHP script. How can I do that?
You can echo in PHP using the following format
echo "Hello world!";
It will simply output the string Hello World! to the frontend. I am assuming that you have already added the PHP tags as:
<?php echo "Hello World!"; ?>
You can also output variables as in the example below.
<?php $txt1 = "Hello "; $txt2 = "World!"; $a = 2; $b = 3; echo "<h3>" . $txt1 . $txt2 . "</h3>"; echo $a + $b; ?>
It will output the following
