PHP

while (!feof($fail)) {
    $medan = explode(",", fgets($fail));
    $berjaya = false;

// remainder of the while block
}

if ($berjaya == true)

The variable $berjaya is defined in the while block, so as soon as the loop ends it no longer exists. So move its definition above the loop and it should work:

PHP

$berjaya = false; // ensure that this variable is not confined to th while block
while (!feof($fail)) {
    $medan = explode(",", fgets($fail));
    $berjaya = false;

// remainder of the while block
}

if ($berjaya == true)
