PHP 3 syntax imcompatibilities

Hello, Recently I was brought to the attention that there are some syntax problems in my forms class that hundreds of users have downloaded from here: http://phpclasses.UpperDesign.com/browse.html/package/1 The problem is that I am not sure what exactly uses on it syntax that was legal on PHP 3 but is not legal at least in PHP 4 beta 3. I have pasted the part of the code that apparently offend the PHP 4 syntax. I wonder if anybody can tell me what and why I can't use this syntax in PHP 4 despite I could in PHP 3. $function("function $validate_as_email(theinput)$jseol{$jseol"); $function("\ts=theinput.value$jseol\tif(s.search)$jseol\t{$jseol\t\treturn (s.search(new RegExp(\"".$this->EscapeJavascriptRegularExpressions($this->email_regular_expression)."\",\"gi\"))>=0)$jseol\t}$jseol"); $function("\tif(s.indexOf)$jseol\t{$jseol\t\tat_character=s.indexOf('@')$jseol\t\tif(at_character<=0 || at_character+4>s.length)$jseol\t\t\treturn false$jseol\t}$jseol"); $function("\tif(s.length<6)$jseol\t\treturn false$jseol\telse$jseol\t\treturn true$jseol}$jseol"); Regards, Manuel Lemos Web Programming Components using PHP Classes.
