Exploding array and adding execution timestamp for each bit of data in the array?
Using curl_multi, I have loaded up 3 url's and then printed the array.
1) How can I also set a timestamp on output to let me know when each url was run?
2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( [0] =>", "[1] =>", "[2] =>" and " )"?
Code
<?php
function multiRequest($data, $options = array()) {
// array of curl handles
$curly = array();
// data to be returned
$result = array();
// multi handle
$mh = curl_multi_init();
// loop through $data and create curl handles
// then add them to the multi-handle
foreach ($data as $id => $d) {
$curly[$id] = curl_init();
$url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
curl_setopt($curly[$id], CURLOPT_URL, $url);
curl_setopt($curly[$id], CURLOPT_HEADER, 0);
curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);
// post?
if (is_array($d)) {
if (!empty($d['post'])) {
curl_setopt($curly[$id], CURLOPT_POST, 1);
curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
}
}
// extra options?
if (!empty($options)) {
curl_setopt_array($curly[$id], $options);
}

}
// execute the handles
$running = null;
do {
curl_multi_exec($mh, $running);
} while($running > 0);
// get content and remove handles
foreach($curly as $id => $c) {
$result[$id] = curl_multi_getcontent($c);
curl_multi_remove_handle($mh, $c);
}
// all done
curl_multi_close($mh);

}
$data = array(array(),array());
$data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json';
$data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json';
$data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json';
$r = multiRequest($data);
print_r($r);
?>
Output
Array ( [0] => Pearl Jam <br>
[1] => Black Eyed Peas<br>
[2] => Nirvana )
Preferred Output
01:00:01 Pearl Jam <br>
01:00:02 Black Eyed Peas<br>
01:00:03 Nirvana
I'd say keep it simple...just do a loop where you set the timestamp and do a single curl call, then explode the resultarray and filter out all key or values you don't need.
For the curl call:
$r= array();
foreach($urls as $url) {
$r[]["timestamp"]= time();
$output= curl_exec($url);
$r[]["bandname"]= $output;
}
Your final loop would be something like
foreach($r as $key=>$value){
print $value["timestamp"];
print $value["bandname"];
print "<br>";
}
