while loop

[Anon]

Once I'm on a page like this...

herodb.php?action=hero&HeroID=1

I want to display the info related to that Hero with that HeroID. I tried the next script...

<?php
while($heroes->("HeroID")){
?>
<?php echo $heroes->f("DOB"); ?> - <?php echo $heroes->f("DOD"); ?>

<?php } ?>

But it seems it doesn't work... get an error like...

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or '{'' or'$'' in hero.php on line 70

Why?

Your problem is $heroes->("HeroID") What is this supposed to mean? Are you trying to call a method of $heroes? If so you don't have the method name just a parameter. Or if you are trying to access a property then you need to loose the parathesis and quotes.

Accessing an object property:

$objname->propname

object method:

$objname->methodname([optional arguments])

Just a general comment, you're making your code harder to read than it needs to be because of excessive <?php ... ?> blocks. Your code could be shortened (and made easier to read/understand) like this:

<?
while ($heroes->methodgoeshere("HeroID")) {
echo $heroes->f("DOB")." - ".$heroes->f("DOD");
}
?>

The . operator that I used there allowed me to include the - on the same line as the echo statement without all the extra code-breaks.
