直接上代碼：
<?php
function bg(){
$str = file_get_contents('http://cn.bing.com/HPImageArchive.aspx?idx='.rand(0,5).'&n=1'); //從bing獲取數據
$reg = "/<url>.*?<\/url>/";
preg_match($reg, $str, $matches);
$b = substr($matches[0],0,-6);
$new = preg_replace("/<url>|<\/url>/is","", $b);
$imgurl='http://cn.bing.com'.$new;
return $imgurl;
}
設置頁面背景(全屏,內容透明背景)
<?php
function bg(){
$str = file_get_contents('http://cn.bing.com/HPImageArchive.aspx?idx='.rand(0,5).'&n=1'); //從bing獲取數據
$reg = "/<url>.*?<\/url>/";
preg_match($reg, $str, $matches);
$b = substr($matches[0],0,-6);
$new = preg_replace("/<url>|<\/url>/is","", $b);
$imgurl='http://cn.bing.com'.$new;
return $imgurl;
}
?>
