Accessing an array in an object

Question

If i knew the correct terms to search these would be easy to google this but im not sure on the terminology.

I have an API that returns a big object. There is one particular one i access via:

$bug->fields->customfield_10205[0]->name;
//result is [email protected]

There is numerous values and i can access them by changing it from 0 to 1 and so on

But i want to loop through the array (maybe thats not the correct term) and get all the emails in there and add it to a string like this:

implode(',', $array);
//This is private code so not worried too much about escaping

Would have thought i just do something like: echo implode(',', $bug->fields->customfield_10205->name);

Also tried echo implode(',', $bug->fields->customfield_10205);

And echo implode(',', $bug->fields->customfield_10205[]->name);

The output im looking for is: '[email protected],[email protected],[email protected]'

Where am i going wrong and i apologize in advance for the silly question, this is probably so newbie

Is this a SimpleXML object? Is it possible to perhaps var_dump() the value of $bug->fields->customfield_10205? — Ja͢ck

And what output do you get instead? If this is SimpleXML, these are not really arrays, so you can access them with [] and foreach but not use array functions. — Fabian Schmengler

You need an iteration, such as

# an array to store all the name attribute
$names = array();

foreach ($bug->fields->customfield_10205 as $idx=>$obj)
{
  $names[] = $obj->name;
}

# then format it to whatever format your like
$str_names = implode(',', $names);

PS: You should look for attribute email instead of name, however, I just follow your code

use this code ,and loop through the array.

$arr = array();
for($i = 0; $i < count($bug->fields->customfield_10205); $i++)
{
    $arr[] = $bug->fields->customfield_10205[$i]->name;
}
$arr = implode(','$arr);

This is not possible in PHP without using an additional loop and a temporary list:

$names = array();
foreach($bug->fields->customfield_10205 as $v)
{
    $names[] = $v->name;
}
implode(',', $names);

You can use array_map function like this

function map($item)
{
    return $item->fields->customfield_10205[0]->name;
}

implode(',', array_map("map", $bugs)); // the $bugs is the original array
