PHP下MAIL的另一解决方案

前一段时间我接触到DEC Tru64 Unix 我在上面装了PHP+APACHE,可以用提供的mail函数始终不能正常发信，于是自编了一个函数，它利用UNIX下的管道和PHP的SOCK函数进行发信，经过实验非常驻成功，下面是此函数原代码。
function mymail($mto,$mcc,$msubject,$mbody)
{
$from="webmaster@backhome.com.cn";
$sign = " ";//随你便写些什么
$sendmailpath="/usr/lib/sendmail";//Semdmail路径
$bound = "========_".uniqid("BCFMail")."==_";//分界符
$headers = "MIME-Version: 1.0 ".
"Content-Type: multipart/mixed; boundary="$bound" ".
"Date: ".date("D, d M H:i:s Y ")." ".
"From: $from ".
"To: $mto ".
"Cc: $mcc ".
"Subject: $msubject ".
"Status: ".
"X-Status: ".
"X-Mailer: MY Email Interface ".
"X-Keywords: ";
$content="--".$bound." "."Content-Type:text/plain;charset="GB2312" ".$mbody.$sign." ";
$end = " "."--".$bound."-- ";
$sock = popen("$sendmailpath -t -f 'webmaster@backhome.com.cn'",'w');
fputs($sock, $headers);
fputs($sock, $content);
fputs($sock, $end);
fputs($sock, ". ");
fputs($sock, "QUIT ");
pclose($sock);
}



>create table stream (
ip text,
sTime int,
visits int,
info text);
<?
if($day<0)$day=0;
$mlink=mysql_connect('localhost','ajax','xxxxxxx');
//统计至今首页被浏览的总次数
$query="select SUM(visits) as tvisits from stream";
$result=mysql_db_query('ajax',$query,$mlink);
echo '<span class="st1">浏览首页总累积次数:';
if($row=mysql_fetch_object($result)){
echo $row->tvisits;
}
$week=array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
for($i=0;$i<=$day;$i++){
echo '<p>';
$ctime1=time()-24*3600*$i;
$ctime2=time()-24*3600*($i-1);
echo '<span class="st4">日期:'.date("m月d日",$ctime1).$week[date("w",$ctime1)];
echo "</span>";
$stoday1=mktime(0,0,0,date(m,$ctime1),date(d,$ctime1),date(Y,$ctime1));
$stoday2=mktime(0,0,0,date(m,$ctime2),date(d,$ctime2),date(Y,$ctime2));
//统计当日首页被浏览的累积次数
$query='select SUM(visits) as tvisits from stream where sTime>=';
$query.=$stoday1.' and sTime<'.$stoday2;
$result=mysql_db_query('ajax',$query,$mlink);
echo '<span class="st3">浏览首页累积次数:';
if($row=mysql_fetch_object($result)){
echo $row->tvisits;
}
//统计当日拜访ip的数量
$query='select * from stream where sTime>='.$stoday1;
$query.=' and sTime<'.$stoday2.' order by sTime DESC';
$result=mysql_db_query('ajax',$query,$mlink);
echo "
浏览总人数:".mysql_num_rows($result);
echo '</span><hr size="1">';
echo '<table border="0" width="100%" cellspacing="0" cellpadding="2" class="st3">';
echo '<tr><td nowrap class="st2">IP位址</td>
<td nowrap class="st2">最近时间</td>

以下是一个风格类似windows资源管理器的树型菜单
将下面的脚本包含到你的页面中
另外需要从资源管理器中截取一些gif图片,祥见脚本中的注释
菜单结构文件的格式为:
tree level|item text|item link|link target|last item in subtree
例如
.<b>Demo menu</b>|javascript: alert('This is the demo menu for TreeMenu 1.0');
..<b>目录1</b>
...<b>子目录 1.1</b>
....item 1.1.1|javascript: alert('Item 1.1.1');
....item 1.1.2|javascript: alert('Item 1.1.1');
...item 1.2|javascript: alert('Item 1.2');
...item 1.3|javascript: alert('Item 1.3');
..<b>子目录 2</b>
...item 2.1|javascript: alert('Item 2.1');
...item 2.2|javascript: alert('Item 2.2');
...<b>子目录 2.3</b>
....item 2.3.1|javascript: alert('Item 2.3.1');
....item 2.3.2|javascript: alert('Item 2.3.2');
