php How to read an array of objects?

Question

Struggling with this problem for an hour now and searched both stackoverflow and google and couldn't find an answer that helped. I have the following from xdebug:

 - list (array)

   -[0] (object)

     ---id  (string)

     ---proj_name  (string)

     ---proj_desc  (string)

I am trying to pull out the value of id. Can anyone tell me how to do this? Thank you.

$list[0]->id

$list is an array containing an object at position 0, therefore this object can be accessed with $list[0]
the object has a property named id, which can be accessed with $object->id

If you have more than one object in the array, then you can loop through the values contained in the array with foreach. For example:

foreach ($list as $object) {
    echo $object->id . "<br/>";
}

This will take each object in the array and display its id value.

I had tried this, but the codeigniter program failed not recognizing the value when I called a controller from my form. Error elsewhere. Thanks for confirming and I am pointed in the right direction to solve now.

Use foreach to loop through the list:

foreach($list as $obj)    // Where $list is the list containing the objects
{
   $id = $obj->id;
}
