php cURL如何从文件中获取返回值

Question

I am using cURL to query a page and the page then does a return rather than an echo or print statement.

It does this because the page calls a class method which returns data, how can i grab that returned data in cURL?

i know that I can return raw information thats echoed in the file, but how about return types?

EDIT:

the page that i am calling via curl has a snippet like this

test.php

$test->getCall();

the method looks like

public function getCall()
{
     $str = 'test';
     return $str;
}

if i do

echo $test->getCall();

in a separate file

then I get test

but in the file that i am passing via cURL uses my own MVC url pattern

so i am calling domain.com/request/getCall/

which then executes the getCall() method, but unless that metho echo's something it won't work.

The getCall() method is used in other scripts and depends on the return value so i cannot change it to echo.

Answer 1

What data is being returned from the return operator? cURL is expecting actual data, it has no understanding of the underlying code being run on a page it requests. You have to feed it data in some way, but if you don't want to echo anything you could set a header and have cURL detect the header.
