Deny the usage of animated avatars

Could you guys try the following code, and report back bugs if there are any?
This snipplet detects if an avatar is animated (or any other .gif)

PHP Code:


		
			
function isAnimated($filename)

{

    $fp = fopen($filename, "rb");

    $whole = fread($fp, filesize($filename));

    $i = -1;

    while($i = strpos($whole, 0x2C, $i+1))

    {

        if(strpos($whole, 0x00, $i-1) == $i-1)

            $c++;

    }

    if($c > 1)

        return true;

    return false;

}

do php if statements work without brackets and without telling an if to end?

PHP Code:


		
			
function isAnimated($filename)

{

    $fp = fopen($filename, "rb");

    $whole = fread($fp, filesize($filename));

    $i = -1;

    while($i = strpos($whole, 0x2C, $i+1))

    {

        if(strpos($whole, 0x00, $i-1) == $i-1) {

            $c++;

        }

    }

    if($c > 1) {

        return true;

    } else {

    return false;

    }

}

Yes they do.
If you do not enclose the content in brackets, it assumes the next line is to be executed if the statement returns true - else it ignores it
