Bug description: Overload extension and _call() breaks classes.
If a class is overloaded and it uses __call() the
overloaded class cannot return anything from its methods.
Example code:
<?php
class Foo {
var $bar = 'barvalue';
function Foo() {
}
function getBar() {
return($this->bar);
}
function printBar() {
print($this->bar);
return('foo');
}
function getAny() {
return('Any');
}
function __call($method,$params,&$return) {
$return=$method($params[0]);
return(true);
}
}
overload('Foo');
$f = new Foo();
print '$f->getBar(): ' . $f->getBar() . "\n";
print '$f->printBar(): '; print $f->printBar(); print "\n";
print '$f->bar: ' . $f->bar . "\n";
print '$f->getAny(): ' . $f->getAny() . "\n";
?>
output is:
$f->getBar():
$f->printBar(): barvalue
$f->bar: barvalue
$f->getAny():
after removing the function __call() from the class it
works as expected. Output is then:
$f->getBar(): barvalue
$f->printBar(): barvaluefoo
$f->bar: barvalue
$f->getAny(): Any
