从VFP数据库结果中获取结果我遇到了一些问题...我的php脚本占用的时间很长 - 大约30分钟，但它应该短得多......
所以有代码负责获取数据库结果：
$connect = odbc_connect("RIS", "", "", SQL_CUR_USE_DRIVER) or die("Error in connection ". odbc_errormsg($connect));
$array = array();
$info = array();
$from = $_GET['from'];
$to = $_GET['to'];
$rez_nap = odbc_exec($connect, "
select
pacientid as pac_pk,
datanapr,
ocered,
rtgapparat,
doctor as doc_naprav,
pk_na,
data_opis,
arst_opis as id_arst_opis
from
napravlenie
where
not arst_opis == '0000' and
not arst_opis == '' and
datanapr between {^".$from."} and {^".$to."}
") or die(odbc_errormsg());
while($row_nap = odbc_fetch_array($rez_nap))
{
echo "<pre>";
var_dump($row_nap);
$rez_opis = odbc_exec($connect, "
select
opis as opisanie,
doctor as doc_opis
from
opisanie_rtg
where
pacientid = '".$row_nap["pac_pk"]."' and
data = '".$row_nap["data_opis"]."' and
ocered = '".$row_nap["ocered"]."'
") or die(odbc_errormsg());
while($row_desc = odbc_fetch_array($rez_opis))
{
$op = explode('@#$', $row_desc['opis']);
$opisanie = iconv( "cp1257", "utf-8", trim( addslashes($op[1]) ) );
$t_nr_i = substr($op[0], 12);
$ttt = explode("[", $t_nr_i);
if ( strlen($ttt[0]) > 12 )
{
$tt_nr_is = explode("-", $ttt[0]);
$t_nr_is_t = substr($tt_nr_is[0], 0, 8);
$t_nr_is_t_2 = substr($tt_nr_is[0], 8, 5);
$row_desc["nr_is"] = $t_nr_is_t."-".$t_nr_is_t_2;
}
else
{
$t_nr_is_t = substr($ttt[0], 0, 8);
$t_nr_is_t_2 = substr($ttt[0], 8, 5);
$row_desc["nr_is"] = $t_nr_is_t."-".$t_nr_is_t_2;
}
$row_desc['opis'] = $opisanie;

$row_personal["filial"] = "r15";
$info[] = array_merge($row_nap, $row_desc, $row_apparat, $row_app_gruppa, $row_personal);
}
}
}
}
}
echo json_encode($info);
odbc_close($connect);
数据库有大约80-90k行数据，我使用odbc驱动程序连接到VFP数据库，数据库也在远程服务器上...任何建议我做错了什么？因为我无法弄清楚我做错了什么......感谢您的任何建议和帮助！
P.S此外，我需要将该响应转换为JSON，然后将其保存到MySQL数据库......
编辑1 我有第二个索引： pacientid，data_opis，进入了pacient table，opisanie和napravlenie
