php页面打开是空白

本帖最后由 woshiyiziyu 于 2014-02-12 18:38 编辑

本人小白，想弄个自助修改apache密码的php页面，从网上照抄了一段代码，但是打开的时候是空白，打开其他系统里自带的php页面正常，求各位出手相助。<?php
error_reporting(E_ALL);

include("./class.Htpasswd.php3");

/*   
*/
$htpasswdfile = "/etc/squid/passwd";


//
echo '<FORM ACTION="'.$PHP_SELF . '" METHOD=POST>';
?>
<Table BORDER><TR>
<TD>Username: </TD>
<TD><INPUT TYPE=text name="username"></TD>
</TR><TR>
<TD>Password: </TD>
<TD><INPUT TYPE=text name="password"></TD>
</TR><TR>
<TD>
<INPUT TYPE=radio NAME=doop VALUE="verify" CHECKED> Verify Password <BR>
<INPUT TYPE=radio NAME=doop VALUE="add" > add user<BR>
<INPUT TYPE=radio NAME=doop VALUE="delete" > delete user <BR>
<INPUT TYPE=radio NAME=doop VALUE="change" > change password <BR>
</TD>
<TD>
<INPUT TYPE=submit name="operation">
</TD></TR>
</TR>
</TABLE>
</FORM>
<?php
if(!isset($operation)) {
}
else {
echo "<FONT COLOR=RED> <HR>";
echo ",please check <BR><HR>";
echo " $username   $password   = [$doop] <BR>";
$handle = new Htpasswd($htpasswdfile);

switch ($doop) {
case 'add':
print "user<BR>";
$retval = $handle->addUser($username, $password);
if($retval) {
print "user [$username] add success!<BR>";
} else {
print "add user [$username] failed.<BR>";
}
break;

case 'change':
print 'change password<BR>';
$retval = $handle->changePass($username, $password);
if($retval) {
print "[$username] success.<BR>";
} else {
print "[$username] failed.<BR>";
}
break;

case 'delete':
print 'delete user<BR>';
$retval = $handle->deleteUser($username);
if($retval) {
print "[$username] is deleted.<BR>";
} else {
print "delete [$username] error.<BR>";
}
break;

case 'verify':
print 'Code to verify user's password<BR>';
$retval = $handle->verifyUser($username, $password);
if($retval) {
print "[$username] verifies okay with password [$password]<BR>";
} else {
print "Verify Error for [$username] with [$password] (wrong password or user doesn't exist!) <BR>";
}

break;

default:
print 'do you want to break? <BR>';
}
echo "</FONT>";
}
?>

不折腾了，换了个方法实现了同样功能，参照http://blog.sina.com.cn/s/blog_6a90edc90100q2al.html。
