获取特定值时,foreach循环获取错误

here is my code below,

<? foreach($goodsview as $key=>$value)
echo $value;
?>

above code works perfectly by displaying all the values in an array, now i need to fetch perticular value using foreach loop itself,

echo $value['myvalue'] ;

but iam getting an error `Illegal string offset 'myvalue' how can we fix this?

    The variable $value is not an array but a string. That's the reason why the error message is being displayed.

    Without seeing the code there's not much to suggest. But in general, this is how foreach loops work:

    Say your array structure is as follows.

    Array
    (
        [name] => Tom
        [gender] => Male
        [age] => 18
    )
    

    To display all the elements, i.e. 'Tom', 'Male', '18', you'd do something like this:

    foreach ($array as $key => $value) {
         echo $arr[$key].'<br>';
    } 
    

    Output:

    Tom
    Male
    18
    

    To retrieve only a particular value:

    For example, if you want to retrieve the person's name, you can do:

    echo $arr['name']; //Tom
    echo $arr['gender']; //Male
    echo $arr['age']; //18
    

    Hope this clears up things for you! :)
