PHP中通过ADO调用Access数据库
我看了那篇《怎样在PHP中通过ADO调用Asscess数据库和COM程序》文章后,马上作了测试,结果失败了。伤心是不是。
怎么办?我只好去PHP官方网站求助,皇天不负有心人,终于我找到了答案——
具体的解决方法如下:
(1)进入http://php.weblogs.com/adodb,下载相应的ZIP包;同MICROSOFT公司的ADO一样,该东东用PHP实现ADO同各种各样数据库打交道(太好了,所有类型的数据库都能处理)。
(2)解包,里面文件很多,不过有用的只有ohtml.inc.php和adodb.inc.php,把它们复制到相应目录下(或是安装php4的缺省目录下c:php4peer,或是当前运行程序目录下,视include()函数而定);
(3)然后在本鸡(错误字一个,是机)的c:myphp目录下(iis下设置通过http://localhost/jhk来访问),造了一个名为test.mdb的access库,里头再造个experts的表……。为了通过DSN来访问,我把刚才的ACCESS库在DSN中取名test。
(4)运行。看着说明书我造了这么个程序:
dbtest.php,内容如下:
include( ohtml.inc.php); // load code common to ADODB
include(adodb.inc.php); // load code common to ADODB
$conn = &ADONewConnection(access); // create a connection
$conn->PConnect( est);// connect to MySQL, agora db
$sql = select name, group1 from experts;
$rs = $conn->Execute($sql);
rs2html($rs,order=2 cellpadding=3,array(Customer Name,Customer ID));
$rs->Close(); // optional
$conn->Close(); // optional
?>
然后,IE中打入:http://localhost/jhk/dbtest.php
唉!结果出来了。 令人基本满意!!
(5) 接着,我又想:还要设置DSN,烦不烦!绕过DSN应如何解决?因为在asp中,我习惯用conn.open("provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.Mappath("../nydatabase.mdb"))来处理mdb库,那速度快呀!
?……想了又想,看了又看……。
找找找,……,嘿嘿,终于在testdatabases.inc.php 中找到了答案! 我再把刚才的程序改编:
include( ohtml.inc.php); // load code common to ADODB
include(adodb.inc.php); // load code common to ADODB
$db = &ADONewConnection("ado_access");
print "
Connecting $db->databaseType...
";$access = est.mdb;
$myDSN = PROVIDER=Microsoft.Jet.OLEDB.4.0;.DATA SOURCE=. $access . ;;.USER ID=;PASSWORD=;;
if (@$db->PConnect($myDSN, "", "", "")) {
print "ADO version=".$db->_connectionID->version."
";
$sql = select name, group1 from experts;
$rs = $db->Execute($sql);
rs2html($rs,order=2 cellpadding=3,array(Customer Name,Customer ID));
} else print "ERROR: Access test requires a Access database $access".
.$db->ErrorMsg();
?>
运行。
一切搞定!

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
