Backward compatibility issue?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. php SNMP.php
2. use PHP/4.3.11
3.

What is the expected output? What do you see instead?
back to prompt ( I think ) when it works properly.  I am currently
recieving this error:

PHP Parse error:  parse error, unexpected T_STRING, expecting
T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in
/var/www/html/snmp_monitor/SNMP4.php on line 30

Line 30:
public static function trap($ip, $varBinds=null, $community='public')

Can this code not be used on this old of a version of PHP?

What version of the product are you using? On what operating system?
Centos 4

Please provide any additional information below.

I ran across this issue as well in php 4.x (had to use it due to project 
constraints). To fix this, convert the file into a flat function file (remove 
the class declaration and class specific prefixes from the functions, then do a 
find/replace on everything 'self::' and replace it with a null value.). 
Finally, in your file that calls the class/function, remove the class call so 
it just reads "trap" and your params. It will then work fine.
