一个FTP树状目录（PHP）

结合js做的,具体的话相应要做修改,比如目录制

<br><script language="javascript"><br>with (document) {<br> write("<style type='text/css'>");<br> write(".child ")<br> write("</style>");<br> }<br>function initit(){<br> divcoll = document.all.tags("div");<br> for (i=0; i<divcoll.length; i++) {<br> whichel = divcoll(i);<br> if (whichel.classname == "child") whichel.style.display = "none";<br> }}<br>function expandit(el) { whichel = eval(el + "child");<br> if (whichel.style.display == "none") {<br> whichel.style.display = "block";<br> }<br> else {<br> whichel.style.display = "none";<br> }<br> }<br>onload = initit;<br></script><br><link href=../main.css rel=stylesheet type=text/css><br><?<br>function hsort($a)<br> {<br> $b='';<br> $c='';<br> for($i=0;$i<count($a);$i++)<br> {<br> $j=substr($a[$i],0,1);<br> if($j=='d')<br> if($i==0)<br> $b=$a[$i];<br> else<br> $b.=' && %%'.$a[$i];<br> else<br> if($i==0)<br> $c=$a[$i];<br> else<br> $c.=' && %%'.$a[$i];<br> }<br> if($b=='')<br> {<br> $ff=explode(' && %%',$c);<br> return $ff;<br> }<br> else<br> {<br> if($c=='')<br> {<br> $ff=explode(' && %%',$b);<br> return $ff;<br> }<br> else<br> {<br> $f1=$b.' && %%'.$c;<br> $ff=explode(' && %%',$f1);<br> return $ff;<br> }<br> }<br> }<br>require("./class/ftp.php");<br>$host='localhost';<br>$user='huyang';<br>$pass='huyang';<br>function ftpurl($url,$konge,$in,$name)<br> {<br> if($konge>10)<br> {}<br> else<br> {<br> global $host,$user,$pass;<br> $ftp=new ftp;<br> $ftp->init($host,$user,$pass);<br> $ftp->initpwd($url);<br> $a=$ftp->mulu();<br> $ftp->close();<br> $a=hsort($a);<br> if($in!=1)<br> {<br> $sss=$name.'child';<br> echo'<div id="'.$sss.'" class="child">';<br> }<br> $v=0;<br> for($i=1;$i<count($a);$i++)<br> {<br> $aa=explode(' ',$a[$i]);<br> $j=substr($aa[0],0,1);<br> if($j=='t')<br> {}<br> elseif($j=='d')<br> {<br> $c=count($aa);<br> $c-=1;<br> if(($aa[$c]=='.')||($aa[$c]=='..'))<br> {}<br> else<br> {<br> $v++;<br> if($in==1)<br> {<br> $name1='url'.$v.'parent';<br> $names='url'.$v;<br> echo'<div id="'.$name1.'" class="parent">';<br> echo'<a href="#" onclick="expandit(';<br> echo"'".$names."'";<br> echo'); return false" ><img src="http://www.163design.net/p/b/img/plus.gif" border=0>'.$aa[$c].'</a></div><br> ';<br> }<br> else<br> {<br> $names=$name.'_'.$v;<br> echo'<a href="#" onclick="expandit(';<br> echo"'".$names."'";<br> echo'); return false" >';<br> for($hu=0;$hu<$konge;$hu++)<br> echo'<img src="http://www.163design.net/p/b/img/spacer.gif" border=0 alt="">';<br> echo'<img src="http://www.163design.net/p/b/img/plus.gif" border=0>'.$aa[$c].'</a><br><br> ';<br> }<br> $url1=$url.'/'.$aa[$c];//may be need to change<br> $konge1=$konge+1;<br> ftpurl($url1,$konge1,0,$names);<br> }<br> }<br> else<br> {<br> $c=count($aa);<br> $c-=1;<br> if($in==1)<br> {<br> $name='url'.$i.'parent';<br> $name1='url'.$i;<br> echo'<div id="'.$name.'" class="parent">';<br> echo'<a href="#"><img src="http://www.163design.net/p/b/img/open.gif" border=0>'.$aa[$c].'</a></div><br> ';<br> }<br> else<br> {<br> echo'<a href="#">';<br> for($hu=0;$hu<$konge;$hu++)<br> echo'<img src="http://www.163design.net/p/b/img/spacer.gif" border=0 alt="">';<br> echo'<img src="http://www.163design.net/p/b/img/open.gif" border=0>'.$aa[$c].'</a><br><br> ';<br> }<br> }<br> }<br> if($in!=1)<br> echo'</div>';<br> }<br> }<br>$ftp=new ftp;<br>$ftp->init($host,$user,$pass);<br>$s=$ftp->pwd();<br>$ftp->close();<br>ftpurl($s,0,1,'url1'); //$s may be need to change<br>?><br>
