php - unexpected 'class' (T_CLASS) only on remote (not in local)

We are developping a CRM.

In local, I have no problem, but in remote (OVH), I have this error message :

Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /home/dubinfo/www/CRM/model/Locataire.php on line 126

This is the code :

public function setVisites($visites) {
    $this->_visites = CheckTyper::isArrayOfModel($visites,
            VisiteMaisonInvestisseur::class, 'visites', __CLASS__);
}

The version of PHP on remote host (OVH) is 5.4.38
