这是什么类型的对象以及如何使用它？

Question

这种类型的数组的名称是什么？

有3个主要部分和4个由“issuedTime”“text”“url”和“validToTime”组成的子部分，您如何开始将其转换为对象？如果只有1个主要部分，然而对于3个主要部分来说做起来相当简单，并且对于每个主要部分没有识别让我挠头从哪里开始。

任何意见赞赏。

[{ 
"issuedTime":"7:13pm Sunday 13 June 2010", 
"text":"\nAmended 7:10pm.\n\nText text and more text\n", 
"url":"\/folder\/fc\/name.png", 
"validToTime":"12:00am Monday 14 June 2010" 
},{ 
"issuedTime":"8:33pm Sunday 13 June 2010", 
"text":"\nText and more text.\n", 
"url":"\/folder\/fc\/name.png", 
"validToTime":"12:00pm Monday 14 June 2010" 
},{ 
"issuedTime":"10:40am Sunday 13 June 2010", 
"text":"\nAnd even more text.", 
"url":"\/folder\/fc\/name.png", 
"validToTime":"12:00am Tuesday 15 June 2010" 
} 
]

下面是如何解析JSON

<?php 
$json = '[{ 
    "issuedTime":"7:13pm Sunday 13 June 2010", 
    "text":"\nAmended 7:10pm.\n\nText text and more text\n", 
    "url":"\/folder\/fc\/name.png", 
    "validToTime":"12:00am Monday 14 June 2010" 
    },{ 
    "issuedTime":"8:33pm Sunday 13 June 2010", 
    "text":"\nText and more text.\n", 
    "url":"\/folder\/fc\/name.png", 
    "validToTime":"12:00pm Monday 14 June 2010" 
    },{ 
    "issuedTime":"10:40am Sunday 13 June 2010", 
    "text":"\nAnd even more text.", 
    "url":"\/folder\/fc\/name.png", 
    "validToTime":"12:00am Tuesday 15 June 2010" 
}]'; 
// Parse the json into a PHP array that holds multiple "stdClass Object"s 
$obj = json_decode($json); 
// Iterate through each "stdClass Object" and show what it contains 
foreach($obj as $var => $value) 
{ 
    echo "Number: $var <br/>";  
    echo "Issued: " . $obj[$var]->issuedTime . "<br/>";      
    echo "Text: " . $obj[$var]->text . "<br/>";  
    echo "URL: " . $obj[$var]->url . "<br/>";  
    echo "Valid to: " . $obj[$var]->validToTime . "<br/>";  
    echo "<br/>"; 
} 
?> 

一旦你有$ OBJ，您可以访问它像在foreach循环以上，或访问，让我们说，在第二个上市的文本可以使用：

echo $obj[1]->text; // Second listing, since the first listing is $obj[0] 

和HTML链接W文字的一样：

echo '<a href="' . $obj[1]->url . '">' . $obj[1]->text . '</a>'; 

Answer 2

JSON (an acronym for JavaScript Object Notation)是一个轻量级基于文本的 开放标准设计用于 人类可读的数据交换。它是从 编程语言派生的 ，用于表示 简单数据结构和关联 数组，称为对象。尽管它与JavaScript的关系为 ，但它与语言无关是 ，几乎每个 编程语言都可以使用解析器 。

您可以轻松地将其转换成PHP数组与json_decode功能，这里是PHP网站的例子：

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; 
var_dump(json_decode($json, true)); 

结果：

array(5) { 
    ["a"] => int(1) 
    ["b"] => int(2) 
    ["c"] => int(3) 
    ["d"] => int(4) 
    ["e"] => int(5) 
} 

的第二个参数json_decode是否应将其转换为关联数组。如果不指定第二个参数，输出将是这样的：

object(stdClass)#1 (5) { 
    ["a"] => int(1) 
    ["b"] => int(2) 
    ["c"] => int(3) 
    ["d"] => int(4) 
    ["e"] => int(5) 
} 

所以，你可以将其转换为数组和循环通过它想：

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; 
$array = json_decode($json, true); 
print_r($array); 

foreach($array as $key => $value) 
{ 
    // manipulate the var $value 
} 

Answer 3

你试过json_decode()？它应该正确解析为stdObject。
