通过PHP你可以轻松的连接到数据库，请求数据并将其显示在你的web站点中，甚至修改数据库中的数据。MySQL是一种很流行的数据库，并且在互联网中有许多有关PHP与MySQ......
$sysdate=ora_getcolumn($cursor,1); printoraerr($cursor);
echo " row = $user, $sysdate \n";
}
echo "Fetched all records \n";
echo "Closing cursor ... \n";
ora_close($cursor);
echo "Closed cursor \n";
echo "Logging off from oracle... \n";
ora_logoff($conn);
echo "Logged off from oracle \n";
?>
显示结果
以下代码演示了怎样查询数据库并将结果输出：
function printoraerr($in_cur, $conn)
{
// 检查Oracle是否出错
// 如果存在错误则显示
// 当指针被激活时每次请求Oracle后调用该函数
// If it encountered an error, we exit immediately
if(ora_errorcode($in_cur))
{echo "Oracle code - ".ora_error($in_cur)." n";
ora_logoff($conn);
exit;
}
return;
}
function exequery($w_qry,$conn)
{
$cursor=ora_open($conn); printoraerr($cursor,$conn);
ora_parse($cursor,$w_qry,0); printoraerr($cursor,$conn);
ora_exec($cursor); printoraerr($cursor,$conn);
$numrows=0;
$w_numcols=ora_numcols($cursor);
// 显示头部
echo " \n";
for ($i=0;$i<$w_numcols;$i )
{
$align=(ora_columntype($cursor,$i)=="NUMBER")?"RIGHT":"LEFT";
echo "\t ".ora_columnname($cursor,$i)." \n";
}
echo " \n";
while(ora_fetch($cursor))
{
echo " \n";
for ($i=0;$i<$w_numcols;$i )
{
$align=(ora_columntype($cursor,$i)=="NUMBER")?"RIGHT":"LEFT";
if(ora_columntype($cursor,$i)=="LONG")
echo " ".
ora_getcolumn($cursor,$i)." \n";
else
echo " ".ora_getcolumn($cursor,$i)." \n";
printoraerr($cursor,$conn);
}
$numrows ;
echo " \n";
}
if ($numrows==0)
echo " Query returned no records \n";
else
{
echo " \n";
echo " Count \n";
echo " $numrows \n";
echo " \n";
}
echo " \n";
ora_close($cursor);
return;
}
// 主程序
if(!($conn=ora_logon("user@SID","password")))
{
echo "Error: Cannot connect to database\n";
exit;
}
$qry="SELECT
deptno \"Dept\"
,empno \"Emp\"
,empnm \"Name\"
,salary \"Salary\"
FROM
employee
ORDER BY 1,2";
exequery($qry);
ora_logoff($conn);
?>
基于HTTP的Oracle登录
将以下代码加在PHP页面代码之前以确认Oracle登录。注意你必须正确设定$ SID。
