Php 如何在stdClass中获取数组

我正在尝试用json解码 像这样

<?php 
$json_url = "http://digitsolutions4u.com/apps_services/statuslist.php?catid=1";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

<?php 
$json_url = "http://digitsolutions4u.com/apps_services/statuslist.php?catid=1";
$json = file_get_contents($json_url);

$data = json_decode($json, true);
// the change ..  ..  ..   ^^^^

echo "<pre>";
print_r($data);
echo "</pre>";
foreach ($json['posts'] as $post) {
    echo $post['statusdesc'] . '<br>';
}
?>

我只想列出页面上所有可用的statusdesc，如 love86.jpg love87.jpg love88.jpg

等等有人能为我提供解决方案（代码）吗？我尝试了几个线程，但都没有成功。

您需要做的就是告诉

json\u decode（）

您希望它将json字符串转换为所有数组，而不是像JSONString预期的那样作为对象

<?php 
$json_url = "http://digitsolutions4u.com/apps_services/statuslist.php?catid=1";
$json = file_get_contents($json_url);

$data = json_decode($json);

//echo "<pre>";
//print_r($data);
//echo "</pre>";

foreach ($json->posts as $post) {
    echo $post->statusdesc . '<br>';
}
?>

然而，更简单的方法是按原样处理它，然后按原样去做

<?php

    $response ='{"posts":[{"statusid":"1329","statusdesc":"love86.jpg"},{"statusid":"1328","statusdesc":"love85.jpg"},{"statusid":"1327","statusdesc":"love84.jpg"},{"statusid":"1326","statusdesc":"love83.jpg"},{"statusid":"1325","statusdesc":"love82.jpg"},{"statusid":"1324","statusdesc":"love81.jpg"},{"statusid":"1323","statusdesc":"love80.jpg"},{"statusid":"1322","statusdesc":"love79.jpg"},{"statusid":"1321","statusdesc":"love78.jpg"},{"statusid":"1320","statusdesc":"love77.jpg"},{"statusid":"1319","statusdesc":"love76.jpg"},{"statusid":"1318","statusdesc":"love75.jpg"},{"statusid":"1317","statusdesc":"love74.jpg"},{"statusid":"1316","statusdesc":"love73.jpg"},{"statusid":"1315","statusdesc":"love72.jpg"},{"statusid":"1314","statusdesc":"love71.jpg"},{"statusid":"1313","statusdesc":"love70.jpg"},{"statusid":"1312","statusdesc":"love69.jpg"},{"statusid":"1311","statusdesc":"love68.jpg"},{"statusid":"1310","statusdesc":"love67.jpg"},{"statusid":"1287","statusdesc":"love66.jpg"},{"statusid":"1286","statusdesc":"love65.jpg"},{"statusid":"1285","statusdesc":"love64.jpg"},{"statusid":"1284","statusdesc":"love63.jpg"},{"statusid":"1283","statusdesc":"love62.jpg"},{"statusid":"1282","statusdesc":"love61.jpg"},{"statusid":"1204","statusdesc":"love60.jpg"},{"statusid":"1203","statusdesc":"love59.jpg"},{"statusid":"1202","statusdesc":"love58.jpg"},{"statusid":"1201","statusdesc":"love57.jpg"},{"statusid":"1200","statusdesc":"love56.jpg"},{"statusid":"1199","statusdesc":"love55.jpg"},{"statusid":"1045","statusdesc":"love54.jpg"},{"statusid":"1044","statusdesc":"love53.jpg"},{"statusid":"1043","statusdesc":"love52.jpg"},{"statusid":"1042","statusdesc":"love51.jpg"},{"statusid":"1004","statusdesc":"love50.jpg"},{"statusid":"1003","statusdesc":"love49.jpg"},{"statusid":"1002","statusdesc":"love48.jpg"},{"statusid":"1001","statusdesc":"love47.jpg"},{"statusid":"1000","statusdesc":"love46.jpg"},{"statusid":"239","statusdesc":"love45.jpg"},{"statusid":"238","statusdesc":"love44.jpg"},{"statusid":"237","statusdesc":"love43.jpg"},{"statusid":"236","statusdesc":"love42.jpg"},{"statusid":"235","statusdesc":"love41.jpg"},{"statusid":"234","statusdesc":"love40.jpg"},{"statusid":"233","statusdesc":"love39.jpg"},{"statusid":"232","statusdesc":"love38.jpg"},{"statusid":"231","statusdesc":"love37.jpg"},{"statusid":"230","statusdesc":"love36.jpg"},{"statusid":"229","statusdesc":"love35.jpg"},{"statusid":"228","statusdesc":"love34.jpg"},{"statusid":"227","statusdesc":"love33.jpg"},{"statusid":"226","statusdesc":"love32.jpg"},{"statusid":"31","statusdesc":"love31.jpg"},{"statusid":"30","statusdesc":"love30.jpg"},{"statusid":"29","statusdesc":"love29.jpg"},{"statusid":"28","statusdesc":"love28.jpg"},{"statusid":"27","statusdesc":"love27.jpg"},{"statusid":"26","statusdesc":"love26.jpg"},{"statusid":"25","statusdesc":"love25.jpg"},{"statusid":"24","statusdesc":"love24.jpg"},{"statusid":"23","statusdesc":"love23.jpg"},{"statusid":"22","statusdesc":"love22.jpg"},{"statusid":"21","statusdesc":"love21.jpg"},{"statusid":"20","statusdesc":"love20.jpg"},{"statusid":"19","statusdesc":"love19.jpg"},{"statusid":"18","statusdesc":"love18.jpg"},{"statusid":"17","statusdesc":"love17.jpg"},{"statusid":"16","statusdesc":"love16.jpg"},{"statusid":"15","statusdesc":"love15.jpg"},{"statusid":"14","statusdesc":"love14.jpg"},{"statusid":"13","statusdesc":"love13.jpg"},{"statusid":"12","statusdesc":"love12.jpg"},{"statusid":"11","statusdesc":"love11.jpg"},{"statusid":"10","statusdesc":"love10.jpg"},{"statusid":"9","statusdesc":"love9.jpg"},{"statusid":"8","statusdesc":"love8.jpg"},{"statusid":"7","statusdesc":"love7.jpg"},{"statusid":"6","statusdesc":"love6.jpg"},{"statusid":"5","statusdesc":"love5.jpg"},{"statusid":"4","statusdesc":"love4.jpg"},{"statusid":"3","statusdesc":"love3.jpg"},{"statusid":"2","statusdesc":"love2.jpg"},{"statusid":"1","statusdesc":"love1.jpg"}]}';

默认情况下

json\u decode

将其解码为对象，而不是关联数组。您只需通过箭头（

->

）符号访问该对象的成员。要获取每篇文章，您可以使用

foreach

循环浏览它们

$json_url = "http://digitsolutions4u.com/apps_services/statuslist.php?catid=1";
$json = file_get_contents($json_url);

将

与第二个参数

true

一起使用。它将json字符串作为关联数组返回。然后像这样使用

array\u column

$elm = json_decode( $json );
var_dump( $elm->posts );

这将返回对象数组（stdClass）

您可以通过以下方式获取其中一个字符串：

或者您可以使用json_decode（$json，true）将json转换为数组

注意：json_decode无法记住您的原始类，因为serialize始终返回stdClass（您可以访问属性，但不能访问原始类的方法）

一个重要的注意事项是仅使用

json_decode

，避免对json字符串进行字符串操作（就像您对

str_replace

所做的那样），使用json_解码（$response_string，true）；和array_column（）一个重要注释的可能重复项仅用于
