Question

我用json_encode对php数组进行编码并将其存储到db中，当我尝试将其解码为php数组时，我得到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json_decode($etablissement['Etablissment']['hoursreservation'])，我使用cakephp。以下解决方案对我不起作用： php json decode 和 json decode in php

Answer 1

<?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);

Answer 2

尝试

$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);

你会得到数组，没有问题。
