PHP uses recursion to create multi-level directories

<?<span>php
</span><span>header</span>('Content-type:text/html;charset=utf8'<span>);
</span><span>echo</span> "Loading time:".<span>date</span>('Y-m-d H:i:s'<span>);
</span><span>sleep</span>(5<span>);
</span><span>echo</span> "<br>"<span>;
</span><span>echo</span> "End time:".<span>date</span>('Y-m-d H:i:s'<span>);
</span><span>//</span><span> 多级目录新建</span><span>function</span> createFolder(<span>$path</span><span>){
    </span><span>if</span>(!<span>file_exists</span>(<span>$path</span><span>)){
        createFolder(</span><span>dirname</span>(<span>$path</span><span>));
        </span><span>mkdir</span>(<span>$path</span>, 0777<span>);
    }
}

createFolder(</span>"/Library/WebServer/Documents/aa/bb/cc"<span>);
</span>?>
