Is this a PHP 4.3.2 bug??

[ppowell]

class MyClass {

 var $isSQLFieldArray = array();

 function MyClass() {}

 function getISSQLFieldArray($field) {
  if ($field) return $this->isSQLFieldArray[$field];
 }

}

If I use this exact class and method in my script, the page that calls it locks up. Even using

error_reporting(E_ALL);

not only produces NOT ONE ERROR/WARNING/ANYTHING, the page STILL locks up cold!! You can't click onto a link or press a form button and go ANYWHERE AT ALL...

However, if I do this:

class MyClass {

 var $isSQLFieldArray = array();

 function MyClass() {}

 function getIsSQLFieldArray($field) {
  if ($field && isset($this->isSQLFieldArray[$field])) return $this->isSQLFieldArray[$field];
 }

}

Everything works just fine and STILL no errors reported by

error_reporting(E_ALL);

What do you all make of this one? The following URLs provided me no information:

http://us4.php.net/isset
http://us4.php.net/return
