由于WINDOWS下面没有类似unix下的find命令，在WIN下开发的朋友有时候需要按内容查找替换文件，特写这个小程序方便操作。
声明：本程序仅为兴趣参考，如有不当之处欢迎指正。对于可能存在的风险，本人不承担任何责任。
功能：按文件内容查找或替换文件，可指定按扩展名。
注意：不具有典型意义的字符替换可能会把不该替换的都替换掉，最好先查找确认。

<style>
.f1 {
width:50px;
}
</style>
<form action="" method=get>
<input type=hidden name="action" value="">
<span class="f1">查找：</span><input type="text" name="pattern" value="<? echo $_REQUEST['pattern']?stripslashes($_REQUEST['pattern']):'' ?>" size=50>
<br>
<span class="f1">替换为：</span><input type="text" name="replacement" value="<? echo $_REQUEST['replacement']?stripslashes($_REQUEST['replacement']):'' ?>" size=50>
<br>
<span class="f1">目录：</span><input type="text" name="directory" value="<? echo $_REQUEST['directory']?stripslashes($_REQUEST['directory']):'.' ?>" size=50>
<br>
<span class="f1">仅检查扩展名</span><input type="text" name="ext" value="<?=$_REQUEST['ext']?>"> （不要加句点，多个请用分号分隔）
<br>
<span class="f1">显示目录结构？</span><input type="checkbox" name="disp" value="1" <?=$_REQUEST['disp']?"checked":""?>>
<br>
<input type="button" value="查找" onclick="this.form.action.value='find';this.form.submit();">
  <input type="button" name="替换" value="替换" onclick="this.form.action.value='replace';this.form.submit();">
</form>
