Is this a PHP bug?

ppowell

Consider this code:

class MyClass {
var $blah;

function MyClass() {
  $this->blah = '';
}

function getBlah() {
  return $this->blah;
}

function setBlah($blah) {
 $this->blah = $blah;
}

}

Here is the question I have for you guys, is this a PHP bug?

<?
$foo =& new MyClass;
$foo->setBlah('hello world');
print_r($foo->blah . "<P>");
// PRODUCES FATAL ERROR: print_r($foo->getBlah() . "<P>");
$foo = null;

If I uncomment the "FATAL ERROR" line above I literally get this fatal error:

Fatal Error: method called upon a non-object in line...

I talked to a PHP guru and he wasn't sure of the behavior either. Perhaps I am missing something about class behavior in PHP but this makes absolutely no sense to me. Can someone else out there figure out if either something is wrong with my class structure or nothing is wrong and PHP has a bug in its class features?

Thanx

if you do:

$blah=$foo->getBlah();
print_r($blah . "<P>");

does it work?

ppowell

No, the exact same error on the line $blah = $foo->getBlah();

It works if I do this though

$blah = $foo->blah;

give us the rest of the error and mark the line it references.

Your code works fine.
What version of php are you trying this on?

ppowell

ok..

FATAL ERROR: method getblah references a non-object on /development/phillip/blah.php on line 4

line 4 (when uncommented):

print_r($foo->getBlah() . "<P>");

PHP 4.1.0

Time for an upgrade. 🙂

Try using print instead of print_r.
Getblah() returns a string not an array.

I use print_r out of habit because it returns anything I ask it to by structure, a scalar, an array or an object.

getBlah() is SUPPOSED to return a string, but instead I get a FATAL ERROR when I try to use it only when $this->name is set in the class constructor; if I don't set it, everything is just fine and dandy with getBlah(), string and all.

I definately think an upgrade is in order.

This works fine on 4.3
