Run mysql commands from php using .sql file

Question

I have made an install wizard for my system. If a user wants to use my system he must make an install before starting to use it. The installer will create databases, tables, procedures and triggers.

Installer can create databases and tables successfully but not triggers nor procedures at all.

My php code explodes a .sql file if line end with ';'. But triggers start with delimiter ;; so the script gets the delimiter as a single query.

This is my php code which is reading .sql file and separates file to queries.

$f = fopen($sql_dump_file,"r+");
$sqlFile = fread($f,filesize($sql_dump_file));
$sqlArray = explode(';',$sqlFile);
//  var_dump($sqlArray);
//Process the sql file by statements
foreach ($sqlArray as $stmt) {
    if (strlen($stmt)>3) {
        //echo $stmt;
        $result = mysqli_query($db,$stmt);
        if (!$result) {
            //echo $stmt;
            echo $sqlErrorCode = mysqli_errno($db);
            echo $sqlErrorText = mysqli_error($db);
            $sqlStmt = $stmt;
            break;
        }
    }
}

I have this error
