PHP looping through array and appending to object - php

Question

I have array of objects like so;
Array
(
[0] => stdClass Object
(
[Job] => stdClass Object
(
[ID] => 123
[Name] => Foo
)
)
[1] => stdClass Object
(
[Job] => stdClass Object
(
[ID] => 456
[Name] => BAR
)
)
)
I need to loop through the array and append some additional information to the object like 'Status', but I'm having some issues.
foreach($arrJobs as $key => $val) {
$arrJobs[$key]->Job->Status = new StdClass;
$arrJobs[$key]->Job->Status = $myStatus;
}
This appears to work, but I get the following warning;
Warning: Creating default object from empty value in...

Answer 1

Yes, create an object first. You cannot assign properties of null. That's why you need an instance of stdClass, php's generic empty class.
$arrJobs[$key] = new stdClass;
$arrJobs[$key]->foo = 1;
// And/or see below for 'nested' ...
$arrJobs[$key]->bar = new stdClass;
$arrJobs[$key]->bar->foo = 1;

Answer 2

According to my understanding to you question you just need to append properties to your existing objects. Don't create new objects in your loop
you just need this
foreach ($arrJobs as $obj)
{
$obj->job->status = $myStatus;
}
See the full code :
<?php
$obj1 = new \stdClass();
$obj1->job = new \stdClass();
$obj1->job->id = 123;
$obj1->job->name = "foo";
$obj2 = new \stdClass();
$obj2->job = new \stdClass();
$obj2->job->id = 456;
$obj2->job->name = "bar";
$array = [$obj1,$obj2];
var_dump($array);
foreach ($array as $obj)
{
$obj->job->status = "the status";
//add any properties as you like dynamicly here
}
echo "<br>\nafter<br>\n";
var_dump($array);
exit;
Now $obj1 and $obj2 has the new property 'status' ,see that demo : (https://eval.in/833410)

Answer 3

for ($i = 0; $i < count($arrJobs); $i++)
{
$arrJobs[$i]->Job->Status = new stdClass;
// other operations
}

Answer 4

Try this,
PHP
<?php
// Sample object creation.
$array = [];
$array = [0 => (object) ['Job'=>(object) ['ID'=>123, 'Name' => 'Foo']]];
foreach($array as $val) {
$val->Job->Status = (object) ['zero' => 0,'one' => 1]; // Status 0 and 1.
}
echo "<pre>";
print_r($array);
?>
Output
Array
(
[0] => stdClass Object
(
[Job] => stdClass Object
(
[ID] => 123
[Name] => Foo
[Status] => stdClass Object
(
[zero] => 0
[one] => 1
)
)
)
)
