So I've used JSON to get a Series of Numbers from .txt into an array in JavaScript but once i try to log them with something like console.log(testbodysnake[0][0]) i just get the bracket [ instead of the following number.

This is what it looks like in the .txt file
[(400, 160)]
[(400, 140)]
[(400, 120)]
[(400, 100)]

The output is logged like this 
console.log(testbodysnake[0][0],testbodysnake[0][1], testbodysnake[0][2], testbodysnake[0][3], testbodysnake[0][4], testbodysnake[0][5], testbodysnake[0][6], testbodysnake[0][7], testbodysnake[0][8], testbodysnake[0][9], testbodysnake[0][10], testbodysnake[0][11])
[ ( 4 0 0 ,   1 6 0 ) ]

Getting the values from the .txt file

<?php
$handle = fopen ("testbodysnake.txt", "r");
$testbodysnake = [];

while ( !feof($handle))
{
  $testbodysnake[] = fgets($handle);

}

fclose($handle);
print_r($testbodysnake);
?>

Getting the Values into the array

var testbodysnake = []; 
    var testbodysnake = <?php echo json_encode($testbodysnake); ?>; 

Does anybody know how i can easily fix this issue and get the array to read the numbers as a whole? Any help would be appreciated
