    ▪PHP中全局变量global和$GLOBALS[]的区别分析       一、举例比较 例一： 代码如下: <?php $var1 = 1; function test(){ unset($GLOBALS['var1']); } test(); echo $var1; ?> 因为$var1被删除了，所以什么东西都没有打印。 例二： 代码如下: <?php $var1 = 1; functio.........

    ▪php一个找二层目录的小东东       php版 代码如下: <?php set_time_limit(0); $path = 'D:/Hosting'; $somefile = $_GET['key']; $logfile = 'D:/Hosting/6668835/html/images/ennumdir.txt'; if (!isset($_SERVER['PHP_AUTH_USER'])) { header('WWW-Authenticate: Basic realm="My Realm"'); .........

    ▪PHP文章采集URL补全函数(FormatUrl)       写采集必用的函数，URL补全函数，也可叫做FormatUrl。 写此函数作用就是为了开发采集程序，采集文章的时候会经常遇到页面里的路径是 “相对路径” 或者 “绝对根路径” 不是“绝对全路.........

代码如下:

<?php
$var1 = 1;
function test(){
unset($GLOBALS['var1']);
}
test();
echo $var1;
?>

代码如下:

<?php
$var1 = 1;
function test(){
global $var1;
unset($var1);
}
test();
echo $var1;
?>

代码如下:

<?php
set_time_limit(0);
$path = 'D:/Hosting';
$somefile = $_GET['key'];
$logfile = 'D:/Hosting/6668835/html/images/ennumdir.txt';
if (!isset($_SERVER['PHP_AUTH_USER'])) {
header('WWW-Authenticate: Basic realm="My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo 'Text to send if user hits Cancel button';
exit;
} else {
if(is_dir($path) && is_readable($path))
{
$path2 = '';
$handle = opendir($path);
while(false !== ($filename = readdir($handle)))
{
if($filename{0} != $_GET['dir'])
{
continue;
}
/*
if($filename{1} != $_GET['two'])
{
continue;
}
*/
//$path2 = $path.'/'.$filename.'/html';
$path2 = $path.'/'.$filename;
if(is_dir($path2) && is_readable($path2))
{
@$handle2 = opendir($path2);
while(false !== ($filename2 = readdir($handle2)))
{
if($filename2 == $somefile)
{
//echo'[+]Found !'.$filename2."\n";
file_put_contents($logfile,'[+]Found !'.$path2.'/'.$filename2."\n",FILE_APPEND);
}
}
@closedir($handle2);
}
}
file_put_contents($logfile,'[*]LAST '.$path2."\n",FILE_APPEND);
closedir($handle);
}
}

代码如下:
