php开发一套随机调取全网壁纸内容，核心代码如下
<?php
//ini_set("display_errors", "On");
//error_reporting(E_ALL | E_STRICT);
//if(!defined("a")) exit("Error 001");
//获取当前主域名
$domainurl="http://".$_SERVER['SERVER_NAME'];
$listnum = array('①','②','③','④','⑤','⑥','⑦','⑧','⑨','⑩');
$myurl = myurl();
if(isset($_GET['q'])){
$q = hd_clearStr($_GET['q']);
}
if(isset($_GET['p'])){
$p=$_GET['p'];
if($p>50){
$p=50;
}
if(REWRITE==1 && strpos(URLRULE2,'{qe}')>-1 && strpos($myurl,'q=')<1&& strpos($myurl,'more=1')<1){
$q = qdecode($q);
$q = htmlspecialchars($q);
}
}else{
$p=1;
if(REWRITE==1 && strpos(URLRULE1,'{qe}')>-1 && strpos($myurl,'q=')<1&& strpos($myurl,'more=1')<1){
$q = qdecode($q);
$q = htmlspecialchars($q);
}
}
$s = urlencode($q);
