$user = ” , $passwd = ” ,
$cursor_type = 0) { !$dsn && $this->debug(’dsn not provided!’); $this->con = odbc_connect($dsn ,$user
, $passwd ,$cursor_type); !$this->con && $this->debug(’conncet failed!’); return $this->con; } function query($sql = ”) { $this->resource = odbc_exec($this->con , $sql); !$this->resource && $this->debug
(’query failed!’); return $this->resource; } function fetch_array($resource = ”) { !$resource && $resource = $this->resource; return odbc_fetch_array($resource); } function query_first($sql = ”) { $resource = $this->query($sql); return odbc_fetch_array($resource); } function fetch_all($resource = ”) { !$resource && $resource = $this->resource; $results = array(); while(false !== ($row = @odbc_fetch_
array($resource))) { $results[] = $row; } return $results; } function num_rows() { return odbc_num_rows($this->con); } function affected_rows() { return odbc_num_rows($this->con); } function debug($message = ”) { $message .= ‘ 以下错误信息由ODBC 提供:’. odbc_errormsg(); exit($message); } function __destruct() { odbc_close($this->con); } } ?> 以上就是PHP应用odbc的全部方法步骤，希望对大家有所帮助。
