为这问题 我开启了好久没用的linux 最终发现是缓存的问题  
PHP code

<?php
ob_start();
for($i = 1; $i <= 100; $i++){
    ob_end_flush();//关闭缓存
    $sourceName = 'filetoupload' . $i;
    $imageArray = array();
    $message = "Image $i has been uploaded to the server";
    echo $message;
    flush();
    ob_flush();
    usleep(500000);
}
ob_end_flush(); 
?>

这个缓冲和浏览器相关，和apache的某些模块也相关。
keep try
===================================
PHP code
ob_end_clean();
apache_setenv('no-gzip', 1);
ini_set('zlib.output_compression', 0);
ini_set('implicit_flush', 1);
ob_start();//开始缓冲数据
for($i = 1; $i <= 100; $i++){
    $sourceName = 'filetoupload' . $i;
    $imageArray = array();
    $message = "Image $i has been uploaded to the server<br/>";
    echo $message.str_repeat(" ",1024);//ie有默认的1k buffer
    ob_flush();
    flush();
    usleep(500000);
}
