Re: PHP 4.0 Bug #9195: Default class function arguments

No, it's more complicated than that. Actually, it's not that complicated if you explain it the other way around: - The only case in which a char-by-char comparison is made, is if both arguments are strings, and at least one of them doesn't "look" like a number. Or, in other words: - If at least one of the arguments is not a string, a numeric comparison is made. - If both arguments are strings, but both of them look like numbers, a numeric comparison is made. - If both arguments are strings (and at least one of them doesn't look like a number), a string comparison is made.

After doing a few tests and some reading, it looks like the rule is pretty simple: If either expression on either side of a == operator looks like a number, then the value of the expression is converted to a number. --zak ----- Original Message ----- From: "Zeev Suraski" <zeev@zend.com> To: <nathan@cjhunter.com> Cc: <php-dev@lists.php.net> Sent: Friday, February 09, 2001 11:06 AM Subject: Re: [PHP-DEV] PHP 4.0 Bug #9195: Default class function arguments Default function arguments have to be static, non dynamic values. The way to do it is function foo($bar=unset) {

         if (!isset($bar)) {
                 $bar = ...;
         }

Bug description: Default class function arguments I'm requesting that the default function arguments for a class method be able to reference the class variable members in it's definition. Here is an example of it's use: class searchclass {

        var $hits;
        var $results;

        function save($filename, $start = 0, $end = $this->hits){ /* <-

this returns Parse error: */

                if($fp = @fopen($filename, "w")){
                        for($i = $start; $i < $end; $i++){
                                fwrite($fp, implode("|",

$this->results[$i]));

                        }
                }else{
                        return false;
                }
        }

        function search(){
                /* ... */
        }
