如何将json数组解码为php数组json_解码

我用

json\u encode

对一个php数组进行编码，并将其存储到db中，当我试图将其解码到一个php数组中时，得到null

这是我的php数组：

'Etablissment' => array(
    'id' => '79',
    'telephone' => '0620000000',
    'nom' => 'RESTo',
    'nbmaxpersonnes' => '20',
    'hoursreservation' => '{"Lundi":{"matin":{"h_debut":"0630 ","h_fin":"0830 "},"midi":{"h_debut":"0730 ","h_fin":"1300 "}},"Mardi":{"matin":{"h_debut":"0700 ","h_fin":"0500 "},"midi":{"h_debut":"1530 ","h_fin":"1400 "}}}'
),

我想解码

hoursreservation

字段，所以我使用了

json_解码（$etablisement['etablisement']['hoursreservation']）

，我使用的是cakephp。 以下解决方案不适用于我： 和 试试看

$etablissement = array('Etablissment' => array(
     'id' => '79',
     'telephone' => '0620000000',
     'nom' => 'RESTo',
     'nbmaxpersonnes' => '20',
     'hoursreservation' => '{"Lundi":{"matin":{"h_debut":"0630 ","h_fin":"0830 "},"midi":{"h_debut":"0730 ","h_fin":"1300 "}},"Mardi":{"matin":{"h_debut":"0700 ","h_fin":"0500 "},"midi":{"h_debut":"1530 ","h_fin":"1400 "}}}'
));

echo json_decode($etablissement['Etablissment']['hoursreservation'],true);

您将获得数组，它没有问题。

var\u dump（$etablisement['etablisement']['hoursreservation']）；我测试你的json使用json_解码（$json，true）效果很好显示你使用json_解码的代码如果你在json_解码时收到错误或警告，请与usI分享错误日志（$array['eTablishment']['hoursreservation'）（使用您提供的阵列），它工作正常（在我这边）。也许你的数组不是“数组”。
<?php
$etablissement = [
'Etablissment' => array(
    'id' => '79',
    'telephone' => '0620000000',
    'nom' => 'RESTo',
    'nbmaxpersonnes' => '20',
    'hoursreservation' => '{"Lundi":{"matin":{"h_debut":"0630 ","h_fin":"0830 "},"midi":{"h_debut":"0730 ","h_fin":"1300 "}},"Mardi":{"matin":{"h_debut":"0700 ","h_fin":"0500 "},"midi":{"h_debut":"1530 ","h_fin":"1400 "}}}'
)];

$d = json_decode($etablissement['Etablissment']['hoursreservation'], true);
$e = json_last_error();

var_dump($d);
