I get this output after running my php code to retrive all information from the LRS. How to change this into PHP ARRAY?

Answer 1

You need to learn how to use their API documentation, There is no simple "get all the data" that I can see because everything is wrapped in a class with private/protected properties....
Using your provided sample, here is an example of how to "get the actors"
$Statements = getAllActivity()->content->getStatements();
foreach( $Statements as $Statement )
{
print_r( $Statement->getActor() );
print_r( $Statement->getActor()->getName() );
print_r( $Statement->getActor()->getMbox() );
}
Review the script \src\StatementBase.php, this is where I found the getAcator() method

Answer 2

Without your php code I can only assume you are using json_decode($response) instead of json_decode($response, true). Second parameter in this function decides whether to decode into a class as you have or simple array.
