Summary: Using cURL multi to save urls to a file then reading
files - files chopped
Status: Open
Type: Bug
Package: cURL related
Operating System: Mac OS X 10.6.8

Turns out that everything works as expected when you close the original
filehandle just before calling file_get_contents() on the same file. So this is
not a bug, more of an 'undocumented misbehaviour'.
I've pasted the code which works here:

Description:
------------
I'm using curl multi to download files in parallel. In the test script I
specify that I want to put the contents of the download in a file using the
CURLOPT_FILE flag. The file is downloaded correctly, but when I try to
file_get_contents or fopen() on the downloaded file the contents are always
chopped off. If I put the contents of the file in a variable and count the
length of the string it is always 40960 characters max. The file itself
downloads entirely to disk, it's just PHP which won't read it all, and limits
it to 40Kb.
Tested with PHP 5.3.8, 5.3.13 and 5.3.14, the same thing happens with all
versions.
Output of php -v:

This bug not quite the same as this one https://bugs.php.net/bug.php?id=52558
but they could be related.
Test script:
---------------
I've put the code on pastebin, I can upload it again or email it if needed:
http://pastebin.com/mMHVK85Z
Expected result:
----------------
The script should echo out the entire contents of the newly downloaded webpage
(which has been put in a local file).
Actual result:
--------------
Actual result is the first 40960 characters are output. Checking the file
manually with a tail -f will show that the file was downloaded entirely, but
PHP won't display it all.
