分享一个 PHP遍历目录并返回统计目录大小的方法。
代码:
<?<span>php </span><span>$dirname</span> = "test1"<span>; </span><span>//</span><span>mkdir($dirname); //遍历一层目录 </span> <span>function</span> listdir(<span>$dirname</span><span>) { </span><span>$ds</span> = <span>opendir</span>(<span>$dirname</span><span>); </span><span>while</span>(<span>$file</span> = <span>readdir</span>(<span>$ds</span><span>)) { </span><span>$path</span> = <span>$dirname</span>.'/'.<span>$file</span><span>; </span><span>if</span>(<span>is_dir</span>(<span>$file</span><span>)) { </span><span>echo</span> "DIR:".<span>$file</span>."<br>"<span>; </span><span>if</span>(<span>$file</span> != "." && <span>$file</span> != ".."<span>) { listdir(</span><span>$file</span><span>); } } </span><span>else</span><span> { </span><span>echo</span> "FILE:".<span>$file</span> . "<br>"<span>; } } } </span><span>function</span> totdir(<span>$dirname</span>) { <span>//</span><span>对listdir稍加修改 </span> <span>static</span> <span>$tot</span> = 0<span>; </span><span>$ds</span> = <span>opendir</span>(<span>$dirname</span><span>); </span><span>while</span>(<span>$file</span> = <span>readdir</span>(<span>$ds</span><span>)) { </span><span>$path</span> = <span>$dirname</span>.'/'.<span>$file</span><span>; </span><span>if</span>(<span>is_dir</span>(<span>$file</span><span>)) { </span><span>//</span><span>echo "DIR:".$file."<br>"; </span> <span>if</span>(<span>$file</span> != "." && <span>$file</span> != ".."<span>) { </span><span>$tot</span> += totdir(<span>$file</span><span>); } } www</span>.jbxue.<span>com </span><span>else</span><span> { </span><span>//</span><span>echo "FILE:".$file .
