代码：

<?php/*@desc：php下载文件显示进度@param file 待下载文件名@param name 存储到本地文件名*/function downloadprogress($file,$name){$dir = dirname($name);if(!is_dir($dir)){ mkdir($dir,0755,true);}ob_start();set_time_limit(0);$fr = fopen ($file, "rb");if ($fr) { $content = file_get_contents($file); $filesize = strlen($content); $fw = fopen ($name, "wb"); $downlen=0; $last = 0; $diff = 0; echo "["; if ($fw) { while(!feof($fr)) { $data = fread($fr, 1024 * 8 ); $downlen += strlen($data); fwrite($fw, $data, 1024 * 8 ); $percent = round($downlen/$filesize*100,2); $diff += $percent - $last; if($diff > 1){ echo "#"; $diff = 0; } $last = $percent; ob_flush(); flush(); } echo "#]done"; } if ($fr) { fclose($fr); } if ($fw) { fclose($fw); }}}测试：

downloadprogress('2018.rar','aaa/01.rar');输出（cli下）：
