php中如何获取json数组长度
php提取json数组里面的值怎么提? -
先把获取的内容打印出来,看看是不是正常返回的数据filename = ";;$content = file_get_contents($filename);$json = @json_decode($content );if($json){ $city=$json->city;}else{ echo "json解析失败:quot;.$content;}也可以好了吧!
<?php //将所求json字符串赋值给$json json = '{"resultcode":"200","reason":"SUCCESSED!","result":[{"1":{"variety":"Au100g","latestpri":"267.60","openpri":"269.30","maxpri":"269.30","minpri":"267.00","limit":"-0.15%","yespri":"267.99","totalvol":"2有帮助请点赞。

在PHP中可以使用“json_decode()”函数把JSON字符串转为数组,该函数的作用对JSON格式的字符串进行解码,其语法为“json_decode(str,assoc)”,使用时将字符串传入第1个参数并将第2个设置为TRUE即可。示例代码:json = '{"a"1,"b"2,"c"3,"d"4,&希望你能满意。
你这哪是json,这是序列化,用unserialize反序列化就可以得到数组,然后就可以根据键名来取如果你一定要这种字符串来取,那只能正则preg_match('/"logo".*"(.*)"/U', $str, $match);$match[1]就是你要的值,
php 统计json 数组个数 -
思路:将JSON转换为数组然后做一个循环判断值是否为空不为空判断是否为CBD 计数+1
//json格式数据data = '[{ "F_ModuleId":"1","F_ParentId":"0","F_EnCode":"SysManage",}]';//转换成数组arr = json_decode($data,true);//输出var_dump($arr);以上这篇php 将json格式数据转换成数组的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家后面会介绍。
php中怎么把json字符串转换为数组 -
str = '{"hello": "world!"}'; //也可以是类似于'[1, 2, "3", 4]'的json数组$arr = json_decode($str, true); // 如果不加这个true,解析出来会是对象而不是数组print_r($arr);
<?php$arr = '[{"id":1,"gid":0,"title":"小红"},{"id":2,"gid":0,"title":"小明"},{"id":3,"gid":0,"title":"小蓝"},{"id":4,"gid":0,"title":"小白"},{"id":5,
请问下php如何将以下json转化为数组 -
请问下php如何将以下json转化为数组 {"data":{"encodeDict":[{"autoModelCode":"TGD1070SHD","autoModelName":"大众汽车SVW6474CED多用途乘用车"},{"autoModelCode":"TGD1069SHD","autoModelName":"大众汽车SVW6474CED多到此结束了?。 {"data":{"encodeDict":[{"autoModelCode":"TGD1070SHD","autoModelName":到此结束了?。
var_dump(json_decode($json, true));json_decode —对JSON 格式的字符串进行解码望采纳Thx
