Why does the line with echo end in a semicolon?

Every PHP statement needs to end in a semicolon,

which is essentially your way of letting PHP know

that that statement is complete. If you do not end

the statement with a semicolon, you get an error

when you try to run your page.

Some pages use <? only for the opening

delimiter instead of <?php. Is one more correct

than the other?

PHP supports the shorter form of the opening

delimiter, but not by default, so you need to modify

the configuration file in order to use it. Most PHP

developers prefer the longer form.

6 Type the closing PHP
delimiter, ?>.

The PHP is entered onto
the page.

4 Type echo “Hello,
world”;.

5 Press.
