Write a CSV file from a PHP Array

Question

I appreciate there are already a lot of questions around this subject. But, as I\'m not a PHP developer, I\'m struggling to get anything to work for my specific object struc

Answer 1

For writing a PHP array to a CSV file you should use the built in PHP function fputcsv:

Edit:

More specific example based on your data input:

username = "Rein";
    $obj->answer = "Correct";
    $obj->awesomeness = 1000;

    $array_of_objects[] = $obj;
}

// Open a file to write to
$fp = fopen('file.csv', 'wb');

$i = 0;

// Loop the array of objects
foreach( $array_of_objects as $obj )
{
    // Transform the current object to an array
    $fields = array();

    foreach ($obj as $k => $v)
    {
        $fields[ $k ] = $v;
    }

    if( $i === 0 )
    {
        fputcsv($fp, array_keys($fields) ); // First write the headers
    }

    fputcsv($fp, $fields); // Then write the fields

    $i++;
}

fclose($fp);

Edit 2:

Based on new information (you have a JSON string to start with), I'm added this example as a better way to write the data to a CSV file:
