php连接oracle数据库代码

php教程连接oracle数据库教程代码
$conn   =   OCILogon("scott","tiger","你的oracle数据库名字");
$stmt   =   OCIParse($conn,"select   empno,   ename   from   emp");
/*   使用   OCIDefineByName   要在执行   OCIExecute   前   */
OCIDefineByName($stmt,"EMPNO",&$empno);
OCIDefineByName($stmt,"ENAME",&$ename);
OCIExecute($stmt);
while   (OCIFetch($stmt))   {
      echo   "empno:".$empno."n";
      echo   "ename:".$ename."n";
}
OCIFreeStatement($stmt);
OCILogoff($conn);
/*
注明:
php默认状态下是不能与oracle数据库连接的，我们得在php.ini的Windows   Extensions段修改成
extension_dir   =   "所要加载的dll的文件路径"         （如c:phpextensions）
extension=php_oci8.dll
extension=php_oracle.dll
第二步：
iis中设置isapi

//php连接oracle数据库代码二

if ($conn=Ora_Logon("user@TNSNAME","password"))
{
echo "SUCCESS ! Connected to databasen";
}
else
{
echo "Failed :-( Could not connect to databasen";
}
Ora_Logoff($conn);

//连接数据库实例三

$connection = Ora_Logon ("webmaster@zzzyk.com", "123");
if ($connection == false){
    echo Ora_ErrorCode($connection).": ".Ora_Error($connection)."";
    exit;
}
$cursor = Ora_Open ($connection);
if ($cursor == false){
  echo Ora_ErrorCode($connection).": ".Ora_Error($connection)."";
  exit;
}

Ora_Commit ($connection);
Ora_Close ($cursor);
Ora_Logoff ($connection);

/*
说明函数功能:
integer ora_logon(string user , string password)根据指定用户连接oracle数据库服务器
integer ora_open(integer connection)给出的连接上执行查询。PHP生成一个指示器，解析查询
integer ora_do(integer connection, string query)为查询并准备好执行
integer ora_parse(integer cursor, string query)ora_parse函数解析过的查询。
