ASTCC AGI PHP $_GET 问题

AGI Tx >> 200 result=-1 WWW.SHENGFANG.ORG
AGI Rx << GET VARIABLE DIALSTATUS
AGI Tx >> 200 result=1 (ANSWER)
AGI Rx << :::::0::::::::
AGI Tx >> 510 Invalid or unknown command
AGI Rx << GET VARIABLE ANSWEREDTIME
AGI Tx >> 200 result=1 (20)
AGI Rx << ----ANSWER---
AGI Tx >> 510 Invalid or unknown command
AGI Rx << 55555555
AGI Tx >> 510 Invalid or unknown command

$res = $AGI->exec("DIAL $dialstr");
$dialstatus = $AGI->get_variable("DIALSTATUS");
 printf(":::::%d::::%s::::",$dialstatus,$dialstatus);
print "\n";
$answeredtime = $AGI->get_variable("ANSWEREDTIME");
print "----$answeredtime---";
print "\n"; WWW.SHENGFANG.ORG

ASTCC突然又不能写入CDR了，不知道怎么回事，看来看去，好像变量返回不正常。
DEBUG信息很正常，可是取得的值打印就不正常了

ANSWEREDTIME 变成了 状态
$dialstatus 都是 空了 WWW.SHENGFANG.ORG

PHP代码： WWW.SHENGFANG.ORG
if ($actname=="")
{
 $actname="Show";
}
$adminn=new clsadmin();
$adminn->$actname();

HTML代码： WWW.SHENGFANG.ORG
<form name=form3 action="?actname=save" method="post" target="_self">
echo "<a style=cursor:hand onClick=\"javascript:document.form3.submit()\"> 保存</a>";

结果在LINUX下面显示、保存、删除、新增很正常 WWW.SHENGFANG.ORG

本来在WINDOWS下面也正常的，可是突然就不行了
