在PHP中获取cURL流

Question

1. If I run curl_exec with no options, the fetched page gets output on php's standard output (the html page being served back).

2. If I run it with the RETURNTRANSFER option set, I can get the whole page in a variable.

How can I get a stream, that I can then manually parse?

In case 1, I cannot access the data to parse it and in case 2, I need to wait until it is fully downloaded before starting to parse it. I would like something similar to fopen() and fread() where fread($curl_handle, 1000) would return as soon as the first 1000 bytes have been read, and the second call would be return after 2000 bytes have been read, etc.

Answer 1

You might be interested by this answer I gave some time ago : I explained and gave an example of using stream wrappers with curl, to be able to work with the data while it's being fetched -- which seems to be what you want to do.

It's probably not an exact answer to your question, but it could be what you needed to start implementing a solution ;-)
