PHP 批量更新网页内容实现代码

<?php
$path=$DOCUMENT_ROOT;
$path=str_replace("https://www.jb51.net/","\\",$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);
}
fclose($file);
