How Can I Enable PHP Short Tags for Cross-Platform Compatibility?

Enabling PHP Short Tags for Cross-Platform Compatibility

When migrating a web application from Linux to Windows, PHP developers may encounter differences in the rendering of SQL statements. This can be caused by a discrepancy in the usage of short tags. In PHP, short tags are abbreviated versions of opening and closing PHP tags, such as:

<?php  // Long tag
>?     // Short opening tag
?>     // Short closing tag

By default, PHP short tags are disabled for security reasons. However, they can be enabled for backward compatibility or ease of migration.

Enabling Short Tags in PHP.ini

To enable short tags in PHP, search for the following line in the php.ini configuration file:

short_open_tag=Off

Change the value to "On" and save the file:

short_open_tag=On

Restart Apache Server

After making the change in php.ini, restart the Apache server to apply the new settings.

Verify Short Tag Functionality

To verify that short tags are now enabled, save the following PHP script as a file on your server:

<?
echo "PHP short tags are now enabled.";
?>

Open the file in a web browser. If the message "PHP short tags are now enabled." appears, then short tags are successfully enabled.

By enabling PHP short tags, developers can ensure that their code works seamlessly in both Linux and Windows environments, eliminating potential issues caused by differences in tag handling.
