as skippy noted above this is very useful stuff for
interspersed php & html. Here is alternative syntax
example using a bitwise comparison to set checkboxes on and
off to prefill a permissions bitmask calculator form:
<?
$bitmask = 481683;
?>
.... [yada yada yada]....
<input type="checkbox"
name="SOME_PERMISSION_VARIABLE"
value="32768" <? echo($bitmask & 32768 ?
"checked" : ""); ?>>Can perform
some operation<br/>
<input type="checkbox"
name="SOME_OTHER_PERMISSION_VARIABLE"
value="65536" <? echo($bitmask & 65536 ?
"checked" : ""); ?>>Can perform
some other operation<br/>
You supply a bitmask, and it prechecks all the permissions
the user has so you don't need to remember what they already
have to recheck them all individually.
It's much more elegant than traditional if's.
