PHP一个循环的复杂问题?

为什么一个程序设计循环1000,这个循环里面有很多的程序需要来执行,但是,现在有一个问题就是,只能循环到75次.有时200次,有时有是其它值.但一直不能循环到1000

每一次重新执行程序都可以成功的运行程序,但到了最后,就是空白的了,执行也不在执行了

也加过这个 set_time_limit(0); 但是结果一样的

以前没有遇到这样的情况,以前用虚拟主机,现在换成了,独立的服务器. 2003+apache +php4.4.7

给我的感觉是 服务器什么地方的配置没有做好.

请高手们指点一下,在此先谢谢过

也可以加我的QQ:77884739


如果,我改成10次,或者,60次,也可以循环成功10次,或者60次

代码如下:

//for($i=0,$i<$con_html,$i++){
