Erro PHP: Undefined offset: 1

Boa noite,

O script abaixo funciona no meu wamp localhost, porem quando executo ele em meu servidor linux ubuntu apresenta os seguintes erros:

Notice: Undefined offset: 1 in /var/www/html/legado/index.php on line 82

Notice: malformed in /var/www/html/legado/index.php on line 92

Esse é meu script:
