How to abstract a property attribute in an array in PHP?

Question

I would want to abstract a value of a property in the below array. May I know how can I do with php?

print_r($array);

Array
(
   [0] => {property1: 'value12', property2: 'value12', property3: 'value13'}
   [1] => {property1: 'value21', property2: 'value22', property3: 'value23'}
)

May I know how to read the value of attribute property1 of each array?

is the value inside Array[0]{... an object or an array?

If you have an array with objects this might be the way to go:

$myArrayWithObjects = [
    0 => (Object) ['property1' => 'value12', 'property2' => 'value12', 'property3' => 'value13'],
    1 => (Object) ['property1' => 'value21', 'property2' => 'value22', 'property3' => 'value23']
];

echo 'Array with Objects: ' . $myArrayWithObjects[1]->property3 . "\n";
// prints: Array with Objects: value23

you can loop over the "first array" and use the object like so:

foreach($myArrayWithObjects as $myObject) {
    echo 'Array with Objects foreach: ' . $myObject->property2 . "\n";
}

if it is an array with arrays go this way:

$myArray = [
    0 => ['property1' => 'value12', 'property2' => 'value12', 'property3' => 'value13'],
    1 => ['property1' => 'value21', 'property2' => 'value22', 'property3' => 'value23']
];

echo 'Array with arrays: ' . $myArray[1]['property3'] . "\n";
// prints: Array with arrays: value23

and the foreach loop for array with arrays accordingly:

foreach($myArray as $innerArray) {
    echo 'Array with arrays foreach: ' . $innerArray['property2'] . "\n";
}

Maybe add an example using foreach() ? "... of each array ?"
