Looping through query links via CURL and merging result arrays in PHP - php

Question

The following code is supposed to search for a term on twitter, loop through all the result pages and return one big array with the results from each page appended at each step.
foreach($search_terms as $term){
//populate the obj array by going through all pages
//set up connection
$ch = curl_init();
// go through all pages and save in an object array
for($j=1; $j<16;$j++){
$url ='http://search.twitter.com/search.json?q=' . $term .'&rpp=100&page='.$j.'';
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$var[$j] = curl_exec($ch);
curl_close($ch);
$obj = array_merge((array)$obj,(array)json_decode($var[$j], true));
}
}
It doesn't quite work though and am getting these errors:
curl_setopt(): 3 is not a valid cURL handle resource
curl_exec(): 3 is not a valid cURL handle resource
curl_close(): 3 is not a valid cURL handle resource
...... and this is repeated all the way from 3-> 7...
curl_setopt(): 7 is not a valid cURL handle resource
curl_exec(): 7 is not a valid cURL handle resource
curl_close(): 7 is not a valid cURL handle resource

Answer 1

//set up connection
$ch = curl_init();
// go through all pages and save in an object array
for($j=1; $j<16;$j++){
You need the call to curl_init() inside your loop since you close it at the end of each iteration.
