Foreach循环php

Question

我有一个代码，应该搜索所有数据，如表中的某些内容并打印每个数据，但我根本不工作

$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\n"), $row['question']);
    }
}

Answer 1

您的查询中有拼写错误（$中缺少%each$）：

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