Same exact problem and has been driving me nuts. I keep having to revert back
to
PHP 5.3.6 -- I have not tried 5.3.9 yet, but did try 5.3.10 and had the same
issue. I am running loops with curl_multi_select and they always time out
because
of an infinite loop since it's always returning -1

I put some debug code and got to "curl_multi_select" returning -1 no matter
what, which seems to mean failure from the underlying select system call.
So I guess, the conversation between Win7 x64 and cURL in 5.3.10 is not going
smooth.
[2012-02-20 11:42:47] amoo_miki at yahoo dot com
I used these URLs just to make sure the content is small while my original code
looks at various news feeds. I did make sure the URLs return stuff, via simple
usage of cURL too.
The timeout happens within the loop that performs the curl_multi_select.

There were no code changes between 5.3.9 and 5.3.10 that could possibly have
caused this. I notice you are using php.net sites in your test script. We had
some dns problems around the time you reported this. Are you sure this wasn't
related to that?

I've noticed this as well. The function should return as soon as it is finished
I
believe. This could be a CURL issue or a PHP issue. I'm interested to hear what
the dev's say since I've had all kinds of issues with curl_multi_select in
newer
PHP versions. I keep having to revert to 5.3.6.. I've tried 5.3.10 and using
curl_multi_select within a loop checking for != -1 and it causes an infinite
loop
since it always returns -1 on Windows 7 x64/x86, PHP 5.3.10

I hope this helps. curl_multi_select works fine on my PHP 5.3.6 under Windows 7
x64 with the following CURL
information:
cURL support => enabled

Age => 3
Features
AsynchDNS => Yes
Debug => No
GSS-Negotiate => No
IDN => No
IPv6 => Yes

SSL Version => OpenSSL/1.0.0d
ZLib Version => 1.2.3

Under PHP 5.3.10 on Windows 7 x64, curl_multi_select is always returning -1
with the following CURL
information:
cURL support => enabled
cURL Information => 7.24.0
Age => 3
Features
AsynchDNS => Yes
Debug => No
GSS-Negotiate => No

SSL Version => OpenSSL/0.9.8t
ZLib Version => 1.2.5
libSSH Version => libssh2/1.3.0
I am trying to make GET requests to https:// is that helps. I noticed that
there are different versions of
libcurl and OpenSSL used, so it could end up being an issue with either one of
those, most likely libcurl or
PHP itself. Hope this helps!

I have the same problem white them.
Env: win7 + php5.4.0
Use the code as curl_multi-exec
http://cn2.php.net/manual/zh/function.curl-multi-exec.php
cause the final error: Fatal error: Maximum execution time of 30 seconds
exceeded. But it be runing well in php5.3.6
In PHP5.4 , when i replace the under code
---
$active = null;
// æ§è¡æ¹å¤çå¥æ
do {
$mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($mh) != -1) {
do {
$mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
}
--
With
do {
curl_multi_exec($hMultiCurl, $iRunning);
} while ($iRunning > 0);
-
the programe run ok
So the question is the curl_multi_select bug , cause the while infinite loop.

In the document of curl_multi_exec, has a example in the document.
it can run in php 5.2, but php 5.3 and php 5.4 cause cpu load 100%.
the example is:
http://lxr.php.net/";);
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/";);
curl_setopt($ch2, CURLOPT_HEADER, 0);
//create the multiple cURL handle
$mh = curl_multi_init();
//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);
$active = null;
//execute the handles
do {
$mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($mh) != -1) {
do {
$mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
}
//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
