PHP中的非法字符串偏移错误 [英] Illegal string offset error in PHP

问题描述

我用这个函数从db获取数据

Hi,I use this function to fetch the data from db

$data=userInfo("[e-mail]","123");

这是输出

this is the output

Array 
( 
    [kId] => 1 
    [ad] => Ramazan 
    [email] => [e-mail] 
    [sifre] => 123 
    [resim] =>  
) 
1  

但是我无法使用foreach得到字段值。我得到了未定义的索引



我尝试了什么：

But I cant get field values using foreach.I am getting undefined index

What I have tried:

foreach ($data as $key => $value) {
      echo $value["ad"];

     }

推荐答案

data = userInfo（[e-mail]， 123）;

data=userInfo("[e-mail]","123");

这是输出

this is the output

Array 
( 
    [kId] => 1 
    [ad] => Ramazan 
    [email] => [e-mail] 
    [sifre] => 123 
    [resim] =>  
)
