Thanks pierrick, marfil for answers.
But, your codes still dont work:(
I found the answer by putting the following code:
...
while ($mrc == CURLM_CALL_MULTI_PERFORM);
#fix
if(strtoupper(substr(PHP_OS,0,3)) === 'WIN'){
curl_multi_select($this->m_handle, 0.005);
curl_multi_exec($this->m_handle, $active);
}
...

This behavior is probably related to Bug #61141. Can you try this script
$ch1 = curl_init();
curl_setopt_array($ch1, array(CURLOPT_URL=>"http://lxr.php.net/";,
CURLOPT_HEADER=>0, CURLOPT_RETURNTRANSFER=>1));
$mh = curl_multi_init();
curl_multi_add_handle($mh,$ch1);
$active = null;
do $mrc = curl_multi_exec($mh, $active);
while ($mrc == CURLM_CALL_MULTI_PERFORM);
$start_time = microtime(true);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($mh) == -1) {
usleep(100);
}
do $mrc = curl_multi_exec($mh, $active);
while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
curl_multi_remove_handle($mh, $ch1); curl_multi_close($mh);
And let me know if you still have your problem ?

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.

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
