php - 使用 PHP 检索 MySQL 多个查询并处理

Question

到目前为止我有这段代码:

<?php
include('config.php');

$sql = "SELECT senderID as receiverID, msg, time
        FROM msg
        WHERE senderID = 1";

$result = mysql_query($sql);

if (!$result) {
    echo "Could not successfully run query ($sql) from DB: " . mysql_error();
    exit;
}

if (mysql_num_rows($result) == 0) {
    echo "No rows found, nothing to print so am exiting";
    exit;
}

while ($row = mysql_fetch_assoc($result)) {
    echo $row["receiverID"];
    echo $row["msg"];
    echo $row["time"];
}


mysql_free_result($result);
?>

现在，这只是获取信息和内容，它可以工作，唯一的问题是处理部分。看，我可能可以在 Python 中轻松地做到这一点，但我是 PHP 新手，所以，如果有人可以帮助我，因为这是我返回的内容的示例:

1Hello! How are you?!?!?!876765981admin to user 3574769

现在，我实际上想知道如何将它们分割成它自己的变量或者只是单独打印，我不太确定，这就是它应该如何寻找Python的东西:

firstRow = ['1','Hello! How are you?!?!?!','876765981']

secondRow = ['1','admin to user 3','574769']

现在，我不太确定 php 结构或代码。

Answer 1

在 php 中，你得到的是:

[
    1 => ["receiverId"=>'1',
          "msg"=>'Hello! How are you?!?!?!',
           "time"=>'876765981'],
    2 =>  ["receivedId"=>'1',
           "msg"=>'admin to user 3',
            "time"=>'574769']
]

获取第一行

$firstrow = $result[1]

打印

echo $firstrow["msg"];

$result 是一个嵌套关联数组
