Import du réseau sous nagios

Bonjour,
je souhaite mettre a jour nagios, c'est pourquoi j'exporte la base de donnée de oreon afin de conserver mes 'host' pour ne pas avoir a recommencer mais lorsrque je l'importe sous centron
j'obtien une erreur sur la ligne 153 du fichier importé (à la fonction numRows() ) en PHP voici le fichier :

function microtime_float() {
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}

set_time_limit(60);
$time_start = microtime_float();

$advanced_search = 0;
