Actually this is a PEAR problem. PEAR is not compatible with PHP 5. It
is designed for PHP 4 only.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
For 5.0.x this is expected behavior. __toString() will only called
automatically for echo and print constructs.
Maybe we\'ll change that for 5.1.

Description:
------------
The ZEND_CHANGES defines that __toString method whould
be called whenever object is casted to sting. But actually it is
casted to string only during print (echo) operator.
Even the example in ZEND_CHANGES does not work:
class Foo {
function __toString() {
return "What ever";
}
$obj = Foo;
$str = (string) $obj; // call __toString()
echo $obj; // call __toString()
print $str will print the "Object" sring, not the "What ever".
One more code example:
class Integer {
private $value;
function __construct($val) {
$this->value = $val;
}
function __toString() {
return (string)($this->value);
}
}
$i = new Integer(10);
if (10 == $i)
echo '10!!!! :-)';
"10!!! :-)" is not printed.
Expected result:
----------------
When object is accessed in expressions it should be explicitly
casted to sting nor vartype.
