Re: __toString() with cast is broken in php5 RC1

I think this is an interesting idea. The downside is that __toString() would need special treatment in the engine (possibly even an extra opcode). The upside is that people could always use __toString(). Andi At 03:55 PM 4/2/2004 +1200, Jevon Wright wrote:

Can you add a default __toString() for all objects (which don't extend or implement a __toString()) then? Because at least then we could use $str = $anyobj->__toString(). Otherwise I don't think __toString() has any real functionality, except for print and echo...

Hi Marcus,

Is this going to change back? The php5 documentation on the zend site shows that both casting and print/echo should work.

I guess people could use the output buffering methods to get the print data for the time being. A not so happy work around :(

Thanks again, David

Hello David,

that's correct.      See the NEWS file, 3rd entry:

18 March 2004, PHP 5 Release Candidate 1 - Fixed numerous bugs with the just-in-time auto-global initialization,

that

could cause $_SERVER, $argv/$argc and other variables not to work

properly.

(Zeev) - Fixed data corruption with constant assignments to object properties.

(Zeev)

- Changed __toString() to be called automatically only with print and

echo

statements. (Andi) Friday, April 2, 2004, 1:13:28 AM, you wrote:

Hi There,

I just got a chance tp update to PHP5 RC1 and noticed that some

things

have changed for the __toString method. It seems that it it only

getting

called when the object is printed or echo. Casting the object to a

string

returns the Object #. Here is an example:

---- The Script:

<?php

class obj {

        function __toString()
        {
                return "yo!!\n";
        }

}

$obj = new obj(); print_r($obj);

$test = (string) $obj;

print $test; print $obj;

?>>

----- Produces:

obj Object ( ) Object id #1yo!!
