In the last two days, ive run across code that has php echo'd variables displayed like this
<?=$selected?>
What exactly is going on and why? What is this called?
That's called a Short Tag. It's a shortcut to <?php echo $selected;?>
. It is widely adopted, but there's a lot of literature out there that does not recommend its use as it leads to less portable code (many PHP installations do not have short tags enabled). I happen to agree, just take a look at this user's woes . Also, see:
