返回字符串中的foreach值

Question

I have the code below. I am trying to loop through an array within a string and return the results to be a sub part of the string.

    $household = '{
                "data": {
                    "attributes": {
                        "name":"'.rgar( $entry, '1.6' ).'"
                    },
                    "relationships": {
                        "people":{
                            "data":[
                                '.
                                foreach ($family_ids[] as $fam_member){
                                    return '{"type":"Person","id":"'.$fam_member.'"}';
                                }.'
                            ]
                        },
                        "primary_contact":{
                            "data":{"type":"Person","id":"1"}
                        }
                    }
                }
            }';

            echo($household);

My expected results would be along the lines of this

        '{
                "data": {
                    "attributes": {
                        "name":"'.rgar( $entry, '1.6' ).'"
                    },
                    "relationships": {
                        "people":{
                            "data":[
                                {"type":"Person","id":"2"},
                                {"type":"Person","id":"3"},
                                {"type":"Person","id":"4"}, //note the commas
                                {"type":"Person","id":"5"}
                            ]
                        },
                        "primary_contact":{
                            "data":{"type":"Person","id":"1"}
                        }
                    }
                }
            }';

I believe my issue is related to my quotation marks to break in and out of the string. However I am also not sure how to address to comma being removed for the last result.

You need to assign foreach value to a variable first and then assign this variable to your json.

$data = [];

foreach ($family_ids as $fam_member){
    $data[]= ["type"=>"Person","id"=> $fam_member]
}


$household = '{
                "data": {
                    "attributes": {
                        "name":"'.rgar( $entry, '1.6' ).'"
                    },
                    "relationships": {
                        "people":{
                            "data":'. json_encode($data) . '
                        },
                        "primary_contact":{
                            "data":{"type":"Person","id":"1"}
                        }
                    }
                }
            }';

echo($household);
