php如何设置进度条，我们可以利用php+html来设置具体代码如下
<html> <head> <style type="text/css"><!-- div { margin: 1px; height: 20px; padding: 1px; border: 1px solid #000; width: 275px; background: #fff; color: #000; float: left; clear: right; top: 38px; z-index: 9 } .percents { background: #FFF; border: 1px solid #CCC; margin: 1px; height: 20px; position:absolute; width:275px; z-index:10; left: 10px; top: 38px; text-align: center; } .blocks { background: #EEE; border: 1px solid #CCC; margin: 1px; height: 20px; width: 10px; position: absolute; z-index:11; left: 12px; top: 38px; filter: alpha(opacity=50); -moz-opacity: 0.5; opacity: 0.5; -khtml-opacity: .5 } --> </style> </head> <body> <?php if (ob_get_level() == 0) { ob_start(); } echo str_pad('Loading... ',4096)."<br />\n"; for ($i = 0; $i < 25; $i++) { $d = $d + 11; $m=$d+10; //This div will show loading percents echo '<div class="percents">' . $i*4 . '% complete</div>'; //This div will show progress bar echo '<div class="blocks" style="left: '.$d.'px"> </div>'; flush(); ob_flush(); sleep(1); } ob_end_flush(); ?> <div class="percents" style="z-index:12">Done.</div> </body> </html>
