How to output (echo/print) content in PHP

PHP: How to output (echo/print) content in PHP

There are several ways to output data/content. I might have forgotten about one of them

1) A php file with any content apart from <?php . Without the PHP opening tag, everything else will be echoed out.

2) echo 'some text'; - a simple echo

3) print ('some text'); - similar to echo

4) <?='some text':?> or <?=$a_variable:?>

5) and via functions such as print_r(12345) or var_dump($something)

What is the difference between echo and print in PHP?

There isn't much difference. The only two differences are that echo does not return any value, and can take multiple arguments (echo($a,$b,$b). print() returns a value of 1 and can only take one parameter. Years ago echo() used to be a bit faster, now it would be so insignificant that it is not worth even thinking about which is faster..
