请教 PHP 如何保留文本中的一段特定代码?
@fdipzone
之前PHP里面的INPUT TEXT的问题非常感谢您
我现在可以用VB.NET完成一个修改HTML的功能,但是还是希望用PHP就可以完成,比较省事。
下面这部分VB代码,主要是把c:\vbt.htm打开,然后再掐头去尾,把txtmod之后和subContent之前的代码保留。再生成一个新的htm。
可以用PHP代码实现吗?请指点下。谢谢
Dim a%, b%, s$, sok$ Dim HtmlFile As String HtmlFile = "C:\vb.htm" sok = "" Web1.Navigate(HtmlFile) For Each o In Web1.Document.GetElementsByTagName("div") If InStr(o.innerHTML, "txtmod") > 0 Then s = o.innerHTML a = InStr(o.innerHTML, "txtmod") b = InStr(o.innerHTML, "subContent") sok = Mid(s, a - 1, b - a) sok = Replace(sok, "=txtmod>", "") sok = Replace(sok, "<SPAN class", "") Exit For End If Next
回复讨论(解决方案)
$s = file_get_contents('t1.html');preg_match('/txtmod(.+?)subContent/is',$s,$m);file_put_contents('t2.html',$m[1]);
t1.html里面的内容是csdn论坛首页的内容,在里面加了 txtmod和 subContent,在导航栏的开头和结尾
t2.html里面是匹配到的导航栏
php 功能就是强大可能不用安装桌面软件来
