This is my JSON output:
array:2 [
0 => "[{"subject":"Science","date":"2018-08-09 13:03:14","average":4},{"subject":"Science","date":"2018-09-13 13:18:58","average":4}]"
1 => "[{"subject":"Social","date":"2018-08-14 05:59:56","average":4}]"
]
What I want:
[{"subject":"Science","date":"2018-08-09 13:03:14","average":4},{"subject":"Science","date":"2018-09-13 13:18:58","average":4},{"subject":"Social","date":"2018-08-14 05:59:56","average":4}]
I am not certain how to achieve this. I have tried array_merge, array_combine, array_map, json_encode, json_decode—and various combinations of them all! I am obviously missing something.
Here's my code:
// $classroom_subjects references a table, listing subjects
// for each subject, get the assessment data
foreach ($classroom_subjects as $subject) {
$loop_graph_data[] = AssessmentData::select('subjects.short_name as subject', 'assessment_data.created_at as date', 'assessment_data.assessed_level as average')
->join('subjects', 'subjects.id', 'assessment_data.subject_id')
->where('assessment_data.subject_id', $subject->subject_id)
->where('assessment_data.student_id', $student_id)
->whereBetween('assessment_data.created_at', [$current_term->term_start." 00:00:01", $current_term->term_end." 23:59:59"])
->get()
->toJson();
}
// create an empty variable
$kept_data = [];
// loop through each of the assessment_data elements and only
// keep the one's that have data (no empty arrays)
foreach($loop_graph_data as $graph_data) {
if ($graph_data != "[]") {
$kept_data[] = $graph_data;
}
}
I want to "join" the two (or more—this is dynamic) arrays together into one seamless JSON formatted string.
Does someone know how to do this?
