PHP复杂字符串解析，JSON'able？答案

【问题标题】：PHP Complex String Parse, JSON'able?PHP复杂字符串解析，JSON'able？

【问题描述】：

所以我有以下 PHP 字符串：

$output = {"playerId":1178,"percentChange":0.1,"averageDraftPosition":260,"percentOwned":0.1,"mostRecentNews":{"news":"Accardo was called up from Columbus on Monday, the Indians' official Twitter feed reports.","spin":"He'll replace Dan Wheeler on the active roster after carrying a 2.76 ERA over 13 appearances with the Clippers to start the season.","date":"Mon May 14"},"fullName":"Jeremy Accardo"}

我需要的是：“印第安人官方推特报道称，周一，阿卡尔多从哥伦布被召来。” “他将在本赛季开始时在快船队出场 13 次以 2.76 的 ERA 取代丹·惠勒。”作为子串。但我似乎无法找出最好和最优雅的方式来做到这一点。我尝试对字符串进行 JSON_decode，但没有返回任何内容。有任何想法吗？（我正在使用 PHP）

【问题讨论】：

你能给我们一个你用来解析它的代码的sn-p吗？另外，请注意 json_decode 有第二个变量，可让您选择它是数组还是对象。
@sfgiants2010 您的 json 数据包含许多未转义的单引号，我已修复它，请检查我的答案。

【解决方案1】：

这不是string。试试这样：

$output = '{"playerId":1178,"percentChange":0.1,"averageDraftPosition":260,"percentOwned":0.1,"mostRecentNews":{"news":"Accardo was called up from Columbus on Monday, the Indians\' official Twitter feed reports.","spin":"He\'ll replace Dan Wheeler on the active roster after carrying a 2.76 ERA over 13 appearances with the Clippers to start the season.","date":"Mon May 14"},"fullName":"Jeremy Accardo"}';

$object = json_decode($output);
$array = json_decode($output, true);
$string = json_encode($array);

【解决方案2】：

你有几个未转义的字符串，这会导致错误。一个简单的格式可以节省您的时间。

$output = '{
    "playerId":1178,
    "percentChange":0.1,
    "averageDraftPosition":260,
    "percentOwned":0.1,
    "mostRecentNews": {
        "news":"Accardo was called up from Columbus on Monday, the Indians official Twitter feed reports",
        "spin":"Hell replace Dan Wheeler on the active roster after carrying a 2.76 ERA over 13 appearances with the Clippers to start the season.",
        "date":"Mon May 14"
    },
    "fullName":"Jeremy Accardo"
}';
$json = json_decode($output);

【解决方案3】：

你试过了吗？

$output = '{"playerId":1178,"percentChange":0.1,"averageDraftPosition":260,"percentOwned":0.1,"mostRecentNews":{"news":"Accardo was called up from Columbus on Monday, the Indians\' official Twitter feed reports.","spin":"He\'ll replace Dan Wheeler on the active roster after carrying a 2.76 ERA over 13 appearances with the Clippers to start the season.","date":"Mon May 14"},"fullName":"Jeremy Accardo"}';

$array = json_decode($output, true);

echo $array['mostRecentNews']['news'];
echo $array['mostRecentNews']['spin'];

【解决方案4】：

json_encode 仅使用 UTF8。你在用 utf8 吗？你有语法错误。如果你手动定义 json 变量，它可能是这样的；

<?php
$output=<<<JSONSTR
{"playerId":1178,"percentChange":0.1,"averageDraftPosition":260,"percentOwned":0.1,"mostRecentNews":{"news":"Accardo was called up from Columbus on Monday, the Indians' official Twitter feed reports.","spin":"He'll replace Dan Wheeler on the active roster after carrying a 2.76 ERA over 13 appearances with the Clippers to start the season.","date":"Mon May 14"},"fullName":"Jeremy Accardo"}
JSONSTR;
$variable = json_decode($output);
var_dump($variable);
?>
