将PHP字符串转换为JSON数组.

Converting a PHP string to a JSON array.

我在PHP中有一个如下所示的字符串:

I have a string in PHP that looks like this:

intelligence skin weight volume

所需的输出:

PHP中有一种我可以转换它的方法，因此它看起来像这样:

Is there a way in PHP where I can convert it so it looks like this instead:

["skin", "intelligence", "weight", "volume"]

我查看了json_encode()，但只在关键字周围加上了双引号.

I looked at json_encode() but that only put double quotes around the keywords.

推荐答案

如果要创建JSON数组，则必须首先将输入字符串分解为数组.

If you want to create JSON array, you have to first explode your input string into an array.

尝试:

$input  = 'intelligence skin weight volume';
$output = json_encode(explode(' ', $input));
