json_encode使用数组源无法正常工作

In my php I am reading a file and successfully getting each row into an array ($line[1] because its a 3 column CSV and I just need the 2nd value):

while (($line = fgetcsv($file, 1000)) !== false)
    {           
        $course[] = array('course' => $line[1]);            
    }

$course[] correctly contains the array like:

0 => 
array (size=1)
  'course' => string 'Course One' (length=68)
1 => 
array (size=1)
  'course' => string 'Course Two' (length=45)

Problem is I cannot get the array to convert to json using json_encode

$json_res = json_encode($course);

EDIT: So just to be clear, I have array like this

2 => 
array (size=1)
  'course' => string 'Associate Degree of Business Studies' (length=36)
3 => 
array (size=1)
  'course' => string 'Associate Degree of Business Administration' (length=43)

$json_encode , gives me

boolean false

    ok after taking in consideration all the information you provided, your original code should work. Try this out and let me know if it works.

    $file = new SplFileObject("file.csv");
    $file->setFlags(SplFileObject::READ_CSV);
    $course = array();
    foreach ($file as $row) {
        $line = array('course' => $row[1]);
        array_push($course, $line);
    }
    $json_res = json_encode($course);
    var_dump($json_res);
    

    Update: Try this code and let me know if it works:

    $file = fopen('file.csv', 'r');
    $course = array();
    while (($data = fgetcsv($file, 1000, ",")) !== FALSE) {
        $line = array('course' => utf8_decode($data[1]));
        array_push($course, $line);
    }
    $json_res = json_encode($course);
    var_dump($json_res)
    

    ;
