LEARN ABOUT PHP
curl_multi_info_read
CURL_MULTI_INFO_READ(3) 1 CURL_MULTI_INFO_READ(3)
curl_multi_info_read - Get information about the current transfers
SYNOPSIS
array curl_multi_info_read NULL (resource $mh, [int &$msgs_in_queue])
DESCRIPTION
Ask the multi handle if there are any messages or information from the individual transfers. Messages may include information such as an
error code from the transfer or just the fact that a transfer is completed.
Repeated calls to this function will return a new result each time, until a FALSE is returned as a signal that there is no more to get at
this point. The integer pointed to with $msgs_in_queue will contain the number of remaining messages after this function was called.
Warning
The data the returned resource points to will not survive calling curl_multi_remove_handle(3).
PARAMETERS
o $mh
-A cURL multi handle returned by curl_multi_init(3).
o $msgs_in_queue
- Number of messages that are still in the queue
RETURN VALUES
On success, returns an associative array for the message, FALSE on failure.
Contents of the returned array
+-------+---------------------------------------------------+
| Key: | |
| | |
| | Value: |
| | |
+-------+---------------------------------------------------+
| | |
| msg | |
| | |
| | The CURLMSG_DONE constant. Other return values |
| | are currently not available. |
| | |
| | |
|result | |
| | |
| | One of the CURLE_* constants. If everything is |
| | OK, the CURLE_OK will be the result. |
| | |
| | |
|handle | |
| | |
| | Resource of type curl indicates the handle which |
| | it concerns. |
| | |
+-------+---------------------------------------------------+
EXAMPLES
Example #1
A curl_multi_info_read(3) example
<?php
$urls = array(
"http://www.cnn.com/",
"http://www.bbc.co.uk/",
"http://www.yahoo.com/"
);
$mh = curl_multi_init();
foreach ($urls as $i => $url) {
$conn[$i] = curl_init($url);
curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($mh, $conn[$i]);
}
do {
$status = curl_multi_exec($mh, $active);
$info = curl_multi_info_read($mh);
if (false !== $info) {
var_dump($info);
}
} while ($status === CURLM_CALL_MULTI_PERFORM || $active);
foreach ($urls as $i => $url) {
$res[$i] = curl_multi_getcontent($conn[$i]);
curl_close($conn[$i]);
}
var_dump(curl_multi_info_read($mh));
?>
The above example will output something similar to:
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(5) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(7) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(6) of type (curl)
}
bool(false)
