网上找到的用flush()实现;
<?php
ob_start();
ob_implicit_flush(1);
function OutLing(){
   echo  "进度条...<br /><div style=\"width:800px;height:28px;margin:0 auto;border:#000000 solid 1px;\">" ;
   echo "<div id=\"login\" style=\"background:#0000FF;width:1px;height:30px;\"></div></div>\n";
   echo "<script type=\"text/jscript\">\n";
   echo "function $(value){\n";
   echo "document.getElementById(\"login\").style.width =value +  \"px\";\n";
   echo "}\n";
   echo "$(0);\n";
   echo "</script>\n"; 
}function SetLingData($I){
   echo "<script>$(".$I.")</script>"; 
   ob_flush();
   flush();
}OutLing();
ob_end_flush();
For($j = 1; $j <= 10; $j++) { 
  SetLingData($j*80);
  sleep(1); //让程序"睡"一秒钟，会让你把效果看得更清楚 
}
