Write multiple json files in MySql loop


Go to solution Solved by mac_gyver,

I need multiple json files written by their ID number. I call the id separately and also include it in the json file I'm writing. But when I'm writing I'm writing ALL the records in each .json file and not the individual records. 

 

I know I'm just overlooking something but anyone?

 

Here's the code. 

while ($row = $result->fetch_assoc()) {
   $myArray[] = $row;
   $message = json_encode(array($myArray));
   $id = $row['id'];
   $myfile = fopen("message/$id.json", "w") or die("Unable to create file!");
   fwrite($myfile, $message);
   fclose($myfile);
}

Thanks

Because you're continuously adding to an array on every iteration. $myArray[] = $row this pushes $row into the array on every iteration. At the end of the loop, $myArray contains the entire contents of your database result.

 

That variable isn't even necessary. Just do:

$message = json_encode(array($row));

the following is equivalent, without the extra $myarray that's causing all the data to be stacked together, to what you are showing -

while ($row = $result->fetch_assoc()) {
    file_put_contents("message/{$row['id']}.json", json_encode($row));
}
