PHP Syntax Error, Unexpected '{' [duplicate]

EDIT: The problem was fixed. I had to remove all indentation in the file.

I'm trying to return a JSON array from my server but the PHP keeps throwing this error:

[15-Jun-2015 22:46:59 UTC] PHP Parse error: syntax error, unexpected '{' in /home/user/public_html/backend/xstudio/get_all_mods.php on line 10

I've seen many people have problems like this where they're missing a semicolon or something but I just can't find the problem... Here is my code:

<?php

$response = array("success", "message", array()=>"mods");
define('__ROOT__', dirname(dirname(__FILE__)));
require_once(__ROOT__.'/db_connect.php');
$db = new DB_CONNECT();
$result = mysql_query("SELECT *FROM mods") or die(mysql_error());

if(mysql_num_rows($result) > 0) {
    while($row = mysql_fetch_array($result)) {
        $mod = array();
        $mod["mod_id"] = $row["mod_id"];
        $mod["name"] = $row["name"];
        $mod["author"] = $row["author"];
        $mod["description"] = $row["description"];
        $mod["download"] = $row["download"];
        $mod["picture"] = $row["picture"];
        $mod["created_at"] = $row["created_at"];
        $mod["updated_at"] = $row["updated_at"];
        array_push($response["mods"], $mod);
    }
    $response["success"] = 1;
    echo json_encode($response);
} else {
    $response["success"] = 0;
    $response["message"] = "No mods found";
    echo json_encode($response);
}
?>

Any and all help is appreciated, thanks!
