The syntax for PHP code traditionally uses <?php ?>
for opening and closing tags. However, PHP also supports a short form <? ?>
for opening and closing tags, and this is often referred to as the "short open tag" syntax.
The use of short open tags (<? ?>
) can depend on the server configuration. Some servers may have this feature enabled, while others may have it disabled due to security considerations.
Despite its availability, the use of <?php ?>
is generally recommended for better compatibility across different server environments. This helps ensure that your PHP code works consistently, regardless of the server's specific settings.
In summary, while <? ?>
is a valid syntax, <?php ?>
is the more widely accepted and portable form, making it a safer choice in most scenarios.
