我安装了Apache/ php，想调试下列ＰＨＰ代码的效果 <? session_start(); if(!isset($count)) { session_register( "count"); $count = 1; } ?> You have been to this page <?=$count?> times <? $count++; ?> 我用ＦrontPage编程，并调试 <html><head> <meta http-equiv="Content-Type" content="text/html; charset=??????"> <meta name="GENERATOR" content="Microsoft FrontPage 4.0"> <meta name="ProgId" content="FrontPage.Editor.Document"> <title>New Page 34</title> </head><body> <? session_start(); if(!isset($count)) { session_register( "count"); $count = 1; } ?> You have been to this page <?=$count?> times <? $count++; ?> </body></html>然后打开http://localhost/new_page_34.htm.php，得到Warning: session_start(): open(/tmp\sess_d12a8bd008a8cb5981ec5aa7805c30af, O_RDWR) failed: No such file or directory (2) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12Warning: session_start(): Cannot send session cookie - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php:11) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php:11) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12 You have been to this page 1 times Warning: Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3.

<?
session_start();
if(!isset($count)) {
session_register( "count");
$count = 1;
}

我用ＦrontPage编程，并调试
<html><head>

<meta name="ProgId" content="FrontPage.Editor.Document">

<?
session_start();
if(!isset($count)) {
session_register( "count");
$count = 1;
}
?>
You have been to this page <?=$count?> times
<?
$count++;
?>
</body></html>然后打开http://localhost/new_page_34.htm.php，得到Warning: session_start(): open(/tmp\sess_d12a8bd008a8cb5981ec5aa7805c30af, O_RDWR) failed: No such file or directory (2) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12Warning: session_start(): Cannot send session cookie - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php:11) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php:11) in C:\Program Files\Apache Group\Apache2\htdocs\new_page_34.htm.php on line 12

但现在好像已经出来了让frontpage支php的插件,你可在phpe.net上搜索看看!
要放在开头"是指下面代码吗？
<?
session_start();
if(!isset($count)) {
session_register( "count");
$count = 1;
}
?>
用它做什么，用它可能还不如用一个文本编辑器
２．我将程序的头部
<?
session_start();
if(!isset($count)) {
session_register( "count");
$count = 1;
}
?>
放到放到开头，保存时它会跳转到体部＜body>.
３．应该是头部要做一些改变，但不知改什么？或者是用ＦＰ支持ＰＨＰ的插件，有那个知道？

4.我已安装了Ａpache/php,此后修改了php.ini、Ａpache的配置文件后，是否都要重起动Ａpache服务器？
