PHP Notice is raised for undefined offsets

[Nightfirecat]

When trying to get dyes, if the character has no dyes, PHP will raise a notice regarding the array index not being set. Ex: https://github.com/Nightfirecat/RealmEye-API/blob/master/0.2/index.php#L164

Solution would be to change from this structure:

$var = ($temp = $array[0]) ? $temp : "";

to the following:

if (!isset($array[0])) {
    $array[0] = "";
}
$var = $array[0];

I feel this can be written more succinctly (eg. only write $array[0] once), but don't know how I'd do that offhand.

Looks like the only other occurrence is at L166.

Also happens at:

• L166
• L207 (for bp, pet, last_seen, and last_server)
