All,
I came across the following inconsistency between PHP 4 and PHP 5 Build
2195(Jul 24 2003 20:10:21). The error makes sense. I am just curious
about the version inconsistency. Is this due to a change in PHP 5 (as part
of the class enhancements) or is it an oversight?
For my information, please advise.
==Example==
I can initiate a class before it is defined in version 4, but not in 5.
<?
//filename.php
//you can initiate the class before it is defined
$page = new PageClass;
class PageClass{ blah...blah...blah...; }
?>
will work in PHP 4, but will generate an 'Underfine Class' error in PHP 5.
In PHP 5, the above must be written as
<?
//class must be defined first
class ClassName { blah...blah...; }
//class must be defined before it is initiated
$page = new ClassName;
?>
This error makes sense, as you cannot use something that doesn't exist.
I'm mostly curious about the inconsistency between the two versions.
This is not a big issue, but I am curious? Any comments?
