Question

我在用PHP写作。我有这个字符串：

    '[["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","This is example filler text","3:1",4,37],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>"," Filler text is an example usage of a highlighter JQuery plugin utilized for a drupal module. \n ","5:1",5,85],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","Highlights are serialized to when \"save\" button is pressed. \n ","5:3",0,108],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","The serialized J","5:5",0,16]]'

上面的字符串只是一个JavaScript样式的数组数组的字符串。我希望能够做到的是将其转换为实际的PHP数组。但我也希望能够将PHP数组转换回这个确切的字符串。

最终结果与执行这些步骤的最终结果类似（我认为）：

1）删除第一个和最后一个单引号

2）将每个'['字符替换为'array（'和''''字符'）'

因此，我最终会得到一个有效的PHP数组。而且我也不确定我需要采取什么措施来扭转这一过程。

Answer 1

您可以使用json_encode和json_decode：

$php_array = json_decode('[["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","This is example filler text","3:1",4,37],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>"," Filler text is an example usage of a highlighter JQuery plugin utilized for a drupal module. \n ","5:1",5,85],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","Highlights are serialized to when \"save\" button is pressed. \n ","5:3",0,108],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","The serialized J","5:5",0,16]]', true);
$js_array = json_encode($php_array);

试试这个的Javascript

    var string = '[["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","This is example filler text","3:1",4,37],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>"," Filler text is an example usage of a highlighter JQuery plugin utilized for a drupal module. \n ","5:1",5,85],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","Highlights are serialized to when \"save\" button is pressed. \n ","5:3",0,108],["<span class=\"highlighted\" style=\"background-color: yellow;\"></span>","The serialized J","5:5",0,16]]';
$.post("phpfile.php",{data:string},function(data){ var newVar = data.var; },"json");

PHP

<?php $data = json_decode($_POST["data"]); /*CODE*/ echo json_encode(array("var" => $data)); ?>

如何将JSON字符串转换为PHP数组，然后再返回？
