是否可以通过json_encode对这个php数组进行JSON转换？因为这个php数组被调用$data，当我做..
$data
var myJson = <?php echo json_encode($data) ?>; console.log(myJson);
在JavaScript中，它给了我错误。我想知道JSON可以/不能做什么类型的php数组是否有限制。

首先，您需要在安装了PHP的Apache服务器上的一个PHP文件。制作如下文件：
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} ?>
然后是您的JavaScript（在此示例中，我使用jQuery）：
$.getJSON('http://localhost:8888/myfile.php', function(data) { console.log(data); });
这应该是开始将PHP数组添加到JavaScript中的开始。
