数组中的嵌入对象

Question

I have an array named $result, the output for print_r($result) look like this.

Array
(

[0] => Profile Object
    (
        [id] => 3
        [name] => alvis
        [parentLink] => ProfileLink Object
            (
                [href] => web
                [type] => data
            )
    )

[1] => Profile Object
    (
        [id] => 3
        [name] => gorgia
        [parentLink] => ProfileLink Object
            (
                [href] => text
                [type] => values
            )
    )

[2] => Profile Object
    (
        [id] => 4 
        [name] => text
        [parentLink] => ProfileLink Object
            (
                [href] => text
                [type] => values
            )
    )

 )

I tried displaying just the name by using:

foreach ($results[name] as $key => $value) {
            echo $key . ": " . $value."<br>";
            }

but I got an error Cannot use object of type Profile as array.

and when I tried

foreach ($results->name as $key => $value) {
            echo $key . ": " . $value."<br>";
            }

I got another error : Invalid argument supplied for foreach()
is there's away to display the id and the name?

Answer 1

You can use foreach to iterate through each profile object in your array, and then reference the properties of each profile using -> . The code below ignores the numeric index of the array and just uses the id and name from the profile object.

foreach ($result as $profile) {
    echo $profile->id .": ".$profile->name . " <br>";
}

If you want to include the numeric index of the array as well:

foreach ($result as $index=>$profile) {
    echo "(index ". $index .") ".$profile->id.": ".$profile->name." <br>";
}

Answer 2

You need to loop through your $result array using foreach, and then access the "name" attribute using "->" notation.

    foreach ($result as $profile) {
            print $profile->name;
     }

If you want to get all properties of the profile object, you will have to use get_object_vars().

     foreach ($result as $profile) {
           $vars = get_object_vars($profile);
           foreach ($vars as $key => $var) {
                 echo $key . ": " . $var."<br>";
                 // add suitable looping for the ProfileLink object too
           }
     }
