Difference between <?php ?> and <? ?>

[Ammu]

anybody can pls tell me what is the difference between using <?php ...?> and <?...?> tags in php

[johny10151981]

<?...?> is called short tag. If you use short tag you would be able to write php code in short tag. it also can used in HTML TAG. as example

<INPUT TYPE='text' value=<?=$value?>>

But If you want to use a combination of other non php tag it would conflict such as
<?xml ?>

but you can achieve it anyway

To expand on Johny's comment, some servers (Mainly apache) will initiate a PHP code block when <? ?> is used, however, Windows-based servers require <?php ?> tags.
