我有多种方法来检索纸质物体？我尝试 foreach，尝试获取非对象的属性“sample_url”，以及非法字符串偏移量“sample_url”，如何在对象文件中获取sample_url？
"active_joins2": [
{
"join_registration_number": "SS-006672-I-ID",
"join_status": "checked",
"join_tag": "9#science#indonesia#Primary 3",
"student_id": 7502,
"paper": {
"sample_id": 57,
"sample_title": "Science Indonesia Primary 3",
"sample_url":"http:google.com/abc/sample/1548989381.pdf",
"sample_tag": "9#science#indonesia#Primary 3"
}
},
{
"join_registration_number": "MS-006687-I-ID",
"join_status": "checked",
"join_tag": "9#math#indonesia#Primary 3",
"student_id": 7502,
"paper": {
"sample_id": 47,
"sample_title": "Math Indonesia Primary 3",
"sample_url":"http://google.com/sample/1548988991.pdf",
"sample_tag": "9#math#indonesia#Primary 3"
}
}
]
在 Blade View 中
@foreach ($item['active_joins2'] as $row => $val)
@php
$string = str_replace('#',' ',$val['join_tag']);
$exString = explode(" ",$string);
@endphp
<a href="{{}}" style="text-decoration:none;">
<div class="card jismo-practice-paper mx-auto mb-3">
<div class="card-body row">
<div class="col-lg-6 col-xl-6 col-md-6 col-sm-6 col-6">
<div class="subject" style='text-transform: capitalize'>{{$exString[1]}}</div>
<div class="language" style='text-transform: capitalize'>{{$exString[2]}}</div>
</div>
<div class="col-lg-6 col-xl-6 col-md-6 col-sm-6 col-6">
<div class="grade">{{$exString[3]}}</div>
<div class="gradenumber">{{$exString[4]}}</div>
</div>
</div>
</div>
</a>
@endforeach
最佳答案
简单地使用json_decode()，您的json字符串还缺少开始和结束大括号，即{ }
$array = json_decode($object,1);
foreach($array['active_joins2'] as $key=>$value){
echo $value['paper']['sample_url'].PHP_EOL;
}
