我有两个运行相同php脚本的cpanel网站，用于解析csv文件，一个在godaddy服务器上（站点A），一个在hostgator上（站点B）。在站点B上，页面的html部分呈现然后它解析csv，而在站点A上它解析csv然后呈现html部分。
为什么会出现这种不同的行为？我想让Site A像Site B一样执行这个脚本
他们都运行php 5.4并且具有相同的执行时间限制。
以下是php.ini数组name =＆gt;的array_diff_assoc的结果。 local_value。第一个是array_diff_assoc（站点B，站点A），第二个是array_diff_assoc（站点A，站点B）

更新1
在比较ini_get_all时，我发现站点A启用了APC，而站点B没有...这可能是问题吗？在禁用APC时，此实现是否有任何损害？
更新2
我相信我们可以排除implicit_flush，因为两者都设置为false并且将站点A设置为true不会改变行为
更新3
包含ini文件的差异
更新4
我已将网站A的php.ini文件设置为与网站B相同，但行为没有变化，所以我们可以将其排除在外吗？
更新5
虽然它不能模仿站点B的异步性质，但使用
ob_flush();
flush();
刷新缓冲区似乎非常接近，但它不是一个非常干净的解决方案...
