Foreach循环php [关闭]

I've a code whhich should search for all data LIKE something in a table and print each one but I doesn't work at all

$words = explode(" ", $question);
foreach( $words as $each ) {
    $sql = "SELECT * FROM $table WHERE question LIKE '%each%'";
    $result = mysqli_query($conn, $sql);
    while($row = mysqli_fetch_assoc($result)) {
        printf(nl2br("%s
"), $row['question']);
    }
}

You have a typo in the query (missing $ in %each$):

$sql = "SELECT * FROM $table WHERE question LIKE '%$each%'";
