Bug description:callback of private function in parent class works but static
vars are lost
Description:
------------
In the case below where the callback function is private, its static local
variable is lost during call of inherited class,
t if the callback function is private as below, it still gets called, but
the
local static variable is null instead of initialized like in PHP 5.2, where
it
works.
Also if you make the callback function "protected" instead of "private",
the
result is correct, as expected.
This is reproducible at least on PHP 5.3.8.
Test script:
---------------
class ok {
public function t() {
$this->replacer( '*' );
return preg_replace_callback( '/(t)/', array( $this,
'replacer'), 'this
is a simple test' );
}
private function replacer( $input ) {
static $cache = '-';
if ( ! is_array( $input ) ) {
$cache =
$input;
} else {
return $cache . $input[1] . $cache;
}
}
}
class buggyphp extends ok {}
class buggyphptoo extends ok {
public function t() {
return parent::t();
}
}
$buggy = new buggyphp();
echo 'Result buggyphp: ' . $buggy->t();
echo "\n";
$buggy = new buggyphptoo();
echo 'Result buggyphptoo: ' . $buggy->t();
echo "\n";
$a = new ok();
echo 'Result ok: ' . $a->t();
exit();
Expected result:
----------------
Result buggyphp: *t*his is a simple *t*es*t*
Result buggyphptoo: *t*his is a simple *t*es*t*
Result ok: *t*his is a simple *t*es*t*
Actual result:
--------------
Result buggyphp: -t-his is a simple -t-es-t-
Result buggyphptoo: -t-his is a simple -t-es-t-
Result ok: *t*his is a simple *t*es*t*
