有了这个小程序，PHPer就不用手动进行删除计算机上的目录文件了，在练习PHP目录文件操作时就可以用这个函数，在这个基础上还可以增加浏览文件夹目录，然后进行删除。
代码一：
<?<span php
</span><span //</span><span 删除非空目录</span>
<span function</span> d_rmdir(<span $dirname</span><span ) {
</span><span if</span>(!<span is_dir</span>(<span $dirname</span><span )) {
</span><span return</span> <span false</span><span ;
}
</span><span $handle</span> = @<span opendir</span>(<span $dirname</span><span );
</span><span while</span>((<span $file</span> = @<span readdir</span>(<span $handle</span>)) !== <span false</span><span ){
</span><span if</span>(<span $file</span> != '.' && <span $file</span> != '..'<span ){
</span><span $dir</span> = <span $dirname</span> . '/' . <span $file</span><span ;
</span><span is_dir</span>(<span $dir</span>) ? d_rmdir(<span $dir</span>) : <span unlink</span>(<span $dir</span><span );
}
}
</span><span closedir</span>(<span $handle</span><span );
</span><span return</span> <span rmdir</span>(<span $dirname</span><span ) ;
}
</span><span if</span>(d_rmdir("./temp"<span ))
</span><span echo</span> "succes"<span ;
</span><span else</span>
<span echo</span> "false"<span ;
</span><span //</span><span by www.jbxue.com</span>
?>
代码二，来自php中文在线手册：
<?<span php
</span><span //</span><span 删除非空目录
//by www.jbxue.com</span>
functionremove_directory(<span $dir</span><span ){
</span><span if</span>(<span $handle</span>=<span opendir</span>("<span $dir</span>"<span )){
</span><span while</span>(<span false</span>!==(<span $item</span>=<span readdir</span>(<span $handle</span><span ))){
</span><span if</span>(<span $item</span>!="."&&<span $item</span>!=".."<span ){
</span><span if</span>(<span is_dir</span>("<span $dir</span>/<span $item</span>"<span )){
remove_directory(</span>"<span $dir</span>/<span $item</span>"<span );
}</span><span else</span><span {
</span><span unlink</span>("<span $dir</span>/<span $item</span>"<span );
</span><span echo</span>"removing<span $dir</span>/<span $item</span><br> "<span ;
}
}
}
</span><span closedir</span>(<span $handle</span><span );
</span><span rmdir</span>(<span $dir</span><span );
</span><span echo</span>"removing<span $dir</span><br> "<span ;
}
}
</span>?>
代码三：
<?<span php
</span><span //</span><span 删除非空目录
//by www.jbxue.com</span>
functionremoveDir(<span $dirName</span><span )
{
</span><span if</span>(!<span is_dir</span>(<span $dirName</span><span ))
{
returnfalse;
}
</span><span $handle</span>=@<span opendir</span>(<span $dirName</span><span );
</span><span while</span>((<span $file</span>=@<span readdir</span>(<span $handle</span>))!==<span false</span><span )
{
</span><span if</span>(<span $file</span>!='.'&&<span $file</span>!='..'<span )
{
</span><span $dir</span>=<span $dirName</span>.'/'.<span $file</span><span ;
</span><span is_dir</span>(<span $dir</span>)?removeDir(<span $dir</span>):@<span unlink</span>(<span $dir</span><span );
}
}
</span><span closedir</span>(<span $handle</span><span );
returnrmdir(</span><span $dirName</span><span );
}
</span>?>
