while循环，if语句错误[关闭]

Question

For some reason when using this code it gives me a white screen, and I can't find the problem in it?

while ($monsterhp > 0 && $yourhp > 0) {

if ($pokemon4['speed'] => $row['speed']) {

$monsterhp = floor($monsterhp - $mydmg);

if($yourhp > 0) {
$yourhp = floor($yourhp - $monsterdmg);
}

}elseif ($pokemon4['speed'] < $row['speed']) {

$yourhp = floor($yourhp - $monsterdmg);

if ($monsterhp > 0) {
$monsterhp = floor($monsterhp - $mydmg);
}

}
}

Answer 1

you had an error in this operator: => (greater than or equal)

It should be like this: >=
