Grapes are yummy! Don't you like grapes?

So, I was digging through our code trying to make a simple change to this God forsaken website when I stumbled upon this beauty. It was under another gem, a custom implementation of strrpos.

function strrpos_rev2($text, $search, $offset = 500)
// =============================================================================
{
	$search = "grapes";
	$text = "grapes grapes. Grapes are yummy! Don't you like grapes?";
$text_rev = strrev($substr);
$search_rev = strrev($search);

$search_length = strlen($search);
$text_length = strlen($text);
d("text_length: " . $text_length);
d("offset: " . $offset);

$out = "";
$out .= $text . "";
$out .= "0123456789012345678901234567890123456789012345678901234" . "";
$out .= "0         1         2         3         4         5    " . "<font face="courier">";
$out .= "</font>";

if ($offset) // only use part of the string
	$text = substr($text, 0, $offset);
d($text);

$search_start = strripos($text, $search);
d("search_start: " . $search_start);

$search_length = strlen($search);
d("search_length: " . $search_length);

$search_stop = $search_start + $search_length;
d("search_stop: " . $search_stop);

$temp = strripos($text_rev, $search_rev);
d("temp: " . $temp);

$temp2 = $temp + $search_length;
d("temp2: " . $temp2);

$pos = $text_length - $temp2;
d("pos: " . $text_length);

print $out;

}

I like consistency in my function results. If the programmer overwrote the contents of the $offset argument as well, this would be perfect!

Or is this in some sick, twisted language which will optionally skip assignments at the start of a function (before any non-assignment lines) if they're the first assignment to one of the function parameters, and that function has a value? I wouldn't *think* this would be from such a convoluted language, as it obviously handles default values through the prototype specification. However, I have seen that feature in a language (I forget which one) that didn't have prototypes, and I have seen a number of languages which included redundant features from other languages, to provide comfort for people used to those specific programming languages.

Sorry, you're out of luck. It's PHP my friend.
