是否可以通过 json_encode 对这个 php 数组进行 JSON 处理？
因为这个 php 数组被称为 $data 而当我这样做时..
var myJson = <?php echo json_encode($data) ?>;
console.log(myJson);
在 javascript 中，它给我错误。我想知道 JSON 可以/不能做什么类型的 php 数组是否有限制。

最佳答案
首先，您需要在某个安装了 PHP 的 Apache 服务器上有一个 PHP 文件。制作一个这样的文件:
localhost:8888/myfile.php
<?php
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr); // {"a":1,"b":2,"c":3,"d":4,"e":5}
?>
然后你的 JavaScript(在这个例子中我使用 jQuery ):
$.getJSON('http://localhost:8888/myfile.php', function(data) {
console.log(data);
});
这应该是将 PHP 数组引入 JavaScript 的开始。
