类stdClass的对象无法在laravel中转换为字符串

Question

I'm trying to write a a text file using sql query but it shows an error saying:

Object of class stdClass could not be converted to string

Here is my code:

$myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
$ss=DB::select("SELECT  commercial_library FROM tbl_schedule");

$stringData = implode(', ',$ss);
fwrite($myfile, $stringData);
fclose($myfile);

Answer 1

Implode converts an array to a string. I dont think $ss is an array in your case, it looks like an object. That might be the reason you are getting this error.
