[SOLVED] PHP curl_multi_getcontent partial body received

PHP curl_multi_getcontent partial body received

I'm struggling on this problem.

The body I am fetching is not a big one, 3100 chars. Apache logs on the server says the content length was 3100. However, the string returned by curl_multi_getcontent was cut to 1290 characters.

Usually curl_multi_getcontent() works fine, but sometimes we get this weird behaviour.

Any ideas?

Solution

My code was missing the check for transfers in progress.

With transfers in progress:

http_code = 200
errno = 0
download_content_length = total length, e.g. 1M
size_download = current position, <= download_content_length

Seems the while( curlm_multi_exec == CURLM_CALL_MULTI_PERFORM ) is somewhat insufficient. We have to loop with usleep until sizes match for this url or multi_exec second argument announces all urls finished.

Steps to reproduce:

PHP < 5.2, One url with transfer time of several seconds.
