Sorry, the description is wrong - in_array still seems to be working, it's current($array), prev($array) and next($array) that seem to be misbehaving.

before using next, perv and current, you should do reset(). Then, next and prev not only get items, but move array pointer. Please read the manual about that.

That's the behaviour you see in php 4.0.0 and the behaviour I'm used to (that's why there's two times I do "if (in_array("$counter", $items))"). It doesn't work in anything since then.

This code works just fine in PHP 4.0.0 *with* or *without* the reset($items) - it's online and working at

<http://gary-campbell.com/test.php>

This code fails under any version of PHP since then on multiple machines. It's online and failing at

<http://www.educ8r.net/~darron/test3.php>

Here's the code:

<?

for ($counter = 1; $counter < 11; $counter++) {
        $items[$counter] = $counter;
}

for ($counter = 1; $counter < 11; $counter++) {
        print "$counter = $items[$counter]<BR>\n";
}

print "<P>";

for ($counter = 1; $counter < 11; $counter++) {
        print "$counter = $items[$counter]<BR>\n";

        reset($items);
        
        if (in_array("$counter", $items)) {
                $current_item = current($items);
                $previous_item = prev($items);
                print "Current: $current_item<BR>\n";  
                print "Previous: $previous_item<BR>\n";
        }
        
        if (in_array("$counter", $items)) {
                $next_item = next($items);
                print "Next: $next_item<BR>\n";
        }
        
        if ($previous_item) {
                print "Prev Item Exists<BR>\n";
        } else {
                print "Prev Item Does NOT Exist<BR>\n";
        }
        
        if ($next_item) {
                print "Next Item Exists<P>\n";
        } else {
                print "Next Item Does NOT Exist<P>\n";
        }
} 
  
?>

I tried this again on another server - it's a Mandrake 7.0 box. I recompiled Apache with this configure line:

./configure \
--prefix=/usr/local/apache \
--enable-module=so

Then I compiled php-4.0.0 with this line and tested:

./configure --with-apxs=/usr/local/apache/bin/apxs

The code that I posted before worked just fine with php-4.0.0. It's been posted here:

<http://gateway.javelindigital.com/test.phps>
<http://gateway.javelindigital.com/test.php>

I just grabbed the CVS code (8PM MST 09/16/2000) for php4 and recompiled the module with this configure line:

./configure --with-apxs=/usr/local/apache/bin/apxs

Now that I've upgraded to 4.0.3-dev, the code doesn't work.

This is the 4th machine I've tested this on:

<http://froese.org/~darron/test.php>
<http://www.gary-campbell.com/test.php>
<http://www.educ8r.net/~darron/test.php>
<http://gateway.javelindigital.com/test.php>

Only the machine with php-4.0.0 works - the rest all fail.

When you use prev() just after reset(), you get no value - that's OK, because reset() makes array pointer to point to the first element.
You cannot use next() after that too, without reset(), because array pointer is not valid anymore. You need to check that prev() failed and do the reset().
