PHP ACCESS

PHP 读取 access，windows+wmap测试可以。nginx不行。

$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("SpiderResult.mdb");
$conn->Open($connstr);
$rs = new com("ADODB.RecordSet");
$rs->Open("select * from Content",$conn,1,1);
while(! $rs->eof) {
    $f = $rs->Fields(1);
    echo $f->value;
    echo " 　". $rs->Fields(2)->value;
    echo "<br/>";
    $rs->MoveNext();
}
