-Status: Analyzed
+Status: Bogus
Bug Type: Scripting Engine problem
Operating System: windows95
PHP Version: 4.3.0
New Comment:
Sorry, my assumption wasn't right at all.
The error is because $fruit is not initialised in the global
scope.
Try the following:
<?php
function a(){
global $fruit;
$fruit[0] = 'apple';
$fruit[1] = 'orange';
function aa(){
global $fruit;
(array) $fruit;
echo in_array('apple', $fruit) ? 'ok' : 'fail';
}
function ab(){
global $fruit;
if(in_array('apple', array('apple', 'orange'))){
echo 'ok';
} else {
echo 'fail';
}
}
}
a();
aa();
ab();
?>

This problem turned out to be a problem of the scripting engine, rather
than of in_array(), that "global" declarations don't work in nested
functions.

oops
It might be related that you have functions defined in functions. Can
you try without this?

/*
wondering ? bug : bogus;
looks like in_array() can't function well in
functions within functions scope..
May Allah bless all of us!.
