Well, you’ve already configured your software and now are ready to learn PHP. All your PHP documents must be saved with the *.php extension. Be sure to ask your hosts which PHP version is installed on their server. If it is PHP3.0, then save your PHP documents with the *.php3 extension, or ask your hosts if they could upgrade.
PHP code is embedded in your HTML script.
Almost every PHP command is ended with a semi-colon (;).
Your PHP code must be enclosed within the “<?” and “?>” or “<?php” and “?>” brackets.
PRINT “<center>Hi! This is a PHP example.</center>”;
The output in your browser would be:
Hi! This is a PHP example.
Well, we used PHP PRINT command that outputs all statements enclosed in double quotations (“). Notice that we placed HTML commands <center>…</center> within the PRINT statement and the HTML code was interpreted by the browser.
