New install – plugin not working

I’ve had to get to the point of a new install of your plugin, and when I try to activate it I receive the following error message –

Parse error: syntax error, unexpected T_FUNCTION in /home4/lakehill/public_html/wp-content/plugins/slideshow-ck/includes/class.input.php on line 560

I got to this point after having had to delete the initial installation after updating the plugin gave me the dreaded White Screen of Death.

After looking at the class.input.php file, the function located near line 560 is:
(lines 557 – 573)

$source = strtr($source, $ttr);

// Convert decimal
$source = preg_replace_callback(‘/&#(\d+);/m’, function($m)
{
return utf8_encode(chr($m[1]));
}, $source
);

// Convert hex
$source = preg_replace_callback(‘/&#x([a-f0-9]+);/mi’, function($m)
{
return utf8_encode(chr(‘0x’ . $m[1]));
}, $source
);

return $source;

Please advise, since I’d really like to keep using this plugin.
