贴一段php使用Oracle把字符串写入blob字段的代码。

// connect to oracle
    require __SITEROOT."config/oracleConfig.php";
    $conn = oci_connect($databaseConfig[__INTERFACE]['user'],$databaseConfig[__INTERFACE]['password'],$databaseConfig[__INTERFACE]['host']);
    if($format=='xml')
    {
        $stmt = oci_parse($conn,"INSERT INTO api_data_xml(uuid,suuid,original_type,original_xml) VALUES ('$api_data_uuid','$summary_uuid',1, EMPTY_BLOB()) RETURNING original_xml INTO :tex_blob");
    }
    if($format=='json')
    {
        $stmt = oci_parse($conn,"INSERT INTO api_data_xml(uuid,suuid,original_type,original_json) VALUES ('$api_data_uuid','$summary_uuid',2, EMPTY_BLOB()) RETURNING original_json INTO :tex_blob");
    }

    $clob = oci_new_descriptor($conn,OCI_D_LOB);
    oci_bind_by_name($stmt,':tex_blob',$clob,-1, OCI_B_BLOB);
    oci_execute($stmt,OCI_DEFAULT);
    //这个save要写到oci_execute后面，手册上的例子都是错误的
    $clob->save($xml);
    oci_commit($conn);
    $clob->free();
    oci_free_statement($stmt);
