Question

我正在学习php并做一个小项目。我在数据库中有一个city_name表，其中包含列id，名称，经度和纬度。它最多可能有10-15行。现在，当用户加载index.php时，我执行此查询以从city_name表中获取所有数据

$city_name = mysql_query('SELECT * FROM city_name');

从上面的查询中找到的值，我想以下列格式创建一个javascript变量。我想在标签内的相同index.php中执行此操作。

var locations = [
    ['IMaxx', 50.780941, 6.079134],
    ['Aachen-Elisenbrunnen', 50.771680, 6.086472],
    ['Uni-Cinema', 50.776185, 6.079306],
    ['Alter-Posthof', 50.771705, 6.086561],
    ['Cinemaxx', 50.770754, 6.084942]
];

我该怎么做？

Answer 1

只需将其作为JSON字符串回显：

<?php
$arrayFromDB = [
    ['IMaxx', 50.780941, 6.079134],
    ['Aachen-Elisenbrunnen', 50.771680, 6.086472],
    ['Uni-Cinema', 50.776185, 6.079306],
    ['Alter-Posthof', 50.771705, 6.086561],
    ['Cinemaxx', 50.770754, 6.084942]
];

echo "<script>var locations = ".json_encode($arrayFromDB).";</script>";
?>
