通过Javascript加载PHP文件/代码。 [英] Loading a PHP file/code via Javascript.
问题描述
对于交叉发布很抱歉，但我认为它适用于这两种语言。
我们都知道，JavaScript客户端和php是服务器端，（php
代码''允许''在JavaScript服务器上做的事情是不能的。）
php的问题是一段时间后它会超时，（并且用户也是
对于长时间发生的事情一无所知）。
我需要运行一个脚本在服务器上可能需要很长时间。
所以我想的是混合使用JavaScript和PHP
类似的东西，
< script>
var endvalue = 1000; / *服务器可以计算的一些数字
快速* /
var i = 0
while（i< = endvalue）
{
/ **
调用一个可以做一些工作的php文件
somefunction.php？someNumber = i
* /
}
< / script>
这样服务器就能完成工作，而客户端继续前进。
理想情况下，我也会从php脚本中获得返回值/字符串。
我怎么能实现类似的东西？
非常感谢提前。

我自己做过类似的事情：）
我发现最好的方法是让你的冗长的PHP脚本运行在
a隐藏的iframe中，偶尔会吐出大量的javascript（完整的
< script>标记），并在写入每个标记后刷新输出。
javascript可以更新文件显示，或进度条或其他任何内容，即
持有iframe的文档。它的使用非常简单，非常有效。$ / b

另一个选项是使用CURL。写另一个php页面，它需要一个
的参数并将参数传递给这个页面。 CURL存在
一大堆语言。
不是我自己已经探索过这个，但我想AJAX是第三种选择。 />
查看xmlHttpRequest及其对等功能。
祝你好运！

嗯，你有一个小例子吗？我可以试试吗？
''因为我不确定我跟着，如果php在30秒后超时，（
默认），那么真的没有什么可以做的。
我需要将工作分成不到30秒的块，并以某种方式得到
JavaScript来调用每个''chunck''一次一个。
所以我需要JavaScript来打开一个PHP脚本，等待输出和
处理输出。
是不是可以在服务器上调用另一个文件JavaScript并回显
输出？
我希望我的解释清楚。

Hi,
Sorry for the cross posting, but I think it applies to both languages.
As we all know, JavaScript is client side and php is server side, (the php
code is ''allowed'' to do stuff on the server that JavaScript cannot).
The problem with php is that it timeout after a while, (and the user also
has no clue as to what is going on for a long time).
I need to run a script on the server that could take a very long time.
So what I was thinking is mixing both JavaScript and PHP
Something like,
<script>
var endvalue = 1000; /* some number that the server can calculate
quickly */
var i = 0
while (i<=endvalue)
{
/**
call a php file that will do some work
somefunction.php?someNumber=i
*/
}
</script>
That way the server does the work, while the client keeps it going.
Ideally I would also get a return value/string from the php script.
How could I achieve something like that?
Many thanks in advance.

I''ve done something similar to this myself :)
I found the best way to do it is to have your lengthy PHP script running in
a hidden iframe, occasionally spitting out chunks of javascript (in complete
<script> tags), and flushing the output after each tag is written. The
javascript can update a textual display, or a progress bar or whatever, on
the document holding the iframe. It''s really simple to use, and very
effective.

Another option is to use CURL. Write another php-page that takes a
couple of parameters and pass the parameters to this page. CURL exists
for a whole bunch of languages.
Not that I''ve explored this myself, but I guess AJAX is a third option.
Check out xmlHttpRequest and it''s peer functions.
Good luck!

Hum, would you have a small example I could try?
''cause I am not sure I follow, if the php times-out after 30 seconds, (the
default), then there is nothing it can do really.
I need to divide the work in chunks of less that 30 seconds and somehow get
the JavaScript to call each ''chunck'' one at a time.
So I would need JavaScript to open a php script, wait for the output and
handle the output.
Is it not possible to call another file on the server JavaScript and echo
the output?
I hope my explanation is clear.
