在我们的内部系统中,我们有csv&从我们的MySQL数据库为用户(phpexcel)生成的xls文件,但我的老板问是否可以创建一个mdb文件。
我从来没有遇到任何关于动态创建新MDB文件的示例,我想知道它是否可行。我不是任何机会的专家程序员,但我可以管理是否有人可以指导我如何继续。
我们尝试通过向用户提供mdb而不是CSV来减少用户负载/错误,他们必须将其导入Access。目前,他们必须将超过100个csv文件导入Access。
谢谢。

您可以使用COM
来访问MDB驱动程序。有一个位于phpclasses的简单类可以作为它的包装器,您可以使用它来获取灵感或直接移植它,无论哪种方式完全可能:
以下是该类,源链接如下:
<?php
class mdb
{
var $RS = 0;
var $ADODB = 0;
var $RecordsAffected;
var $strProvider = 'Provider=Microsoft.Jet.OLEDB.4.0';
var $strMode = 'Mode=ReadWrite';
var $strPSI = 'Persist Security Info=False';
var $strDataSource = '';
var $strConn = '';
var $strRealPath = '';
var $recordcount = 0;
var $ok = false;
/**
* Constructor needs path to .mdb file
*
* @param string $dsn = path to *.mdb file
* @return boolean success
*/
function mdb( $dsn='Please enter DataSource!' )
{
$this->strRealPath = realpath( $dsn );
if( strlen( $this->strRealPath ) > 0 )
{
$this->strDataSource = 'Data Source='.$this->strRealPath;
$result = true;
}
else
{
echo "<br>mdb::mdb() File not found $dsn<br>";
$result = false;
}
$this->RecordsAffected = new VARIANT();
$this->open();
} // eof constructor mdb()
function open( )
{
if( strlen( $this->strRealPath ) > 0 )
{
$this->strConn =
$this->strProvider.';'.
$this->strDataSource.';'.
$this->strMode.';'.
$this->strPSI;
$this->ADODB = new COM( 'ADODB.Connection' );
if( $this->ADODB )
{
$this->ADODB->open( $this->strConn );
$result = true;
}
else
{
echo '<br>mdb::open() ERROR with ADODB.Connection<br>'.$this->strConn;
$result = false;
}
}
$this->ok = $result;
return $result;
} // eof open()
/**
* Execute SQL-Statement
* @param string $strSQL = sql statement
* @param boolean $getrecordcount = true when a record count is wanted
*/
function execute( $strSQL, $getrecordcount = false )
{
$this->RS = $this->ADODB->execute( $strSQL, &$this->RecordsAffected );
if( $getrecordcount == true )
{
$this->RS->MoveFirst();
$this->recordcount = 0;
# brute force loop
while( $this->RS->EOF == false )
{
$this->recordcount++;
$this->RS->MoveNext();
}
$this->RS->MoveFirst();
}
} // eof execute()
function eof()
{
return $this->RS->EOF;
} // eof eof()
function movenext( )
{
$this->RS->MoveNext();
} // eof movenext()
function movefirst()
{
$this->RS->MoveFirst();
} // eof movefirst()
function close()
{
@$this->RS->Close(); // Generates a warning when without "@"
$this->RS=null;
@$this->ADODB->Close();
$this->ADODB=null;
} // eof close()
function fieldvalue( $fieldname )
{
return $this->RS->Fields[$fieldname]->value;
} // eof fieldvalue()
function fieldname( $fieldnumber )
{
return $this->RS->Fields[$fieldnumber]->name;
} // eof fieldname()
function fieldcount( )
{
return $this->RS->Fields->Count;
} // eof fieldcount()
} // eoc mdb
?>
一个例子:
include 'class_mdb.php';
$mdb = new mdb('mymdbfile.mdb'); // your own mdb filename required
$mdb->execute('select * from table'); // your own table in the mdb file
#
# first example: using fieldnames
#
while( !$mdb->eof() )
{
echo $mdb->fieldvalue('description'); // using your own fields name
echo ' = ';
echo $mdb->fieldvalue( 1 ); // using the fields fieldnumber
echo '<br>';
$mdb->movenext();
}
echo '<br><hr><br>';
#
# Going back to the first recordset for the second example
#
$mdb->movefirst();
#
# This works, too: Make each Field an object. The values change
# when the data pointer advances with movenext().
#
$url = $mdb->RS->Fields(1);
$bez = $mdb->RS->Fields(2);
$kat = $mdb->RS->Fields(3);
while( !$mdb->eof() )
{
# works!
echo $bez->value;
echo ' = ';
echo $url->value;
echo '<br>';
$mdb->movenext();
}
$mdb->close();

要创建新的空Microsoft Access数据库,我们可以使用ADOX。
下面的代码在c:\
中创建一个空的Test.mdb文件 $adox_catalog = new COM("ADOX.Catalog");
$adox_catalog->create('Provider = Microsoft.Jet.OLEDB.4.0; Data Source=c:\Test.mdb');
$adodb_conection = $adox_catalog->activeconnection();
