PHP 批量更新网页内容实现代码

<?php 
$path=$DOCUMENT_ROOT; 
$path=str_replace("/","\\",$path); 
//指定文件夹 
$path=$path."\\web\\study\\"; 
//得到所有文件 
$s=explode("\n",trim(`dir/b/o:gn $path`)); 
//得到文件夹下的所有HTML文件名 
$num=count($s); 
for($i=0;$i<=$num;$i++){ 
if(strpos($s[$i],".htm")==0){ 
unset($s[$i]); 
} 
} 
//print_r($s); 

//批处理网页 
foreach($s as $value){ 
editfile("D:\\MYOA\\webroot\\web\\study\\".$value); 
echo $value."已更新!<br>"; 
} 
//editfile("D:\\MYOA\\webroot\\web\\study\\0105_5.htm"); 
echo "THE END"; 

//自定义函数:截取标签之间的内容 
function get_body($start_str,$end_str,$content){ 
$start_str_num=strlen($start_str); 
$end_str_num=strlen($end_str); 
$a=strpos($content,$start_str)+$start_str_num; 
$b=strpos($content,$end_str)-strpos($content,$start_str)-$start_str_num; 
return substr($content,$a,$b); 
} 
//编辑文件 
function editfile($str){ 
//$str="D:\\MYOA\\webroot\\web\\study\\".$str 
//取得HTML内容 
$file=@fopen($str,"r"); 
while(!feof($file)){ 
$result.=fgets($file,9999); 
}
