note 71445 added to function.in-array

In trying to emulate a case insensitive in_array(), I came
up with ...

<?php
function in_array_caseless($m_Needle, array $a_Haystack,
$b_Strict = False)
    {
    // Let's assume the function will fail.
    $b_Result = False;

    // Compare array vs array
    if (is_array($m_Needle))
        {
        // Iterate the Haystack to compare each Bale with
the Needle.
        foreach($a_Haystack as $a_Bale)
            {
            // Determine the intersection between the Needle
and the Bale.
            // Strictness indicates that the associative
indexes must also match using case insensitivity.
            if (
                ($b_Strict &&
(array_uintersect_uassoc($m_Needle, $a_Bale, 'strcasecmp',
'strcasecmp') === $m_Needle)) ||
                (!$b_Strict &&
(array_uintersect($m_Needle, $a_Bale, 'strcasecmp') ===
$m_Needle))
                )
                {
                // It it matches then we have a winner.
                $b_Result = True;

                // Don't process anything else as 1 match is
all that is required.
                break;
                }
            }
        }

    // Compare everything else but reverse the Haystack and
the Needle.
    // This is done as the return from array_uinterect is
based upon its Needle
    // and we need the Haystack's type to compare for
strictness.
    else
        {
        $a_Result =
array_values(array_uintersect($a_Haystack, array($m_Needle),
'strcasecmp'));
        $b_Result = !$b_Strict || (gettype($m_Needle) ==
gettype($a_Result[0]));
        }

    // Return the result
    return $b_Result;
    }
?>
