change query string parameter

Question

how do I go on about changing query string like for example i have this curl request for an api

www.apiurl.com/page=1&content=3

i need to request like 60 pages so which is the simple way instead of repeating the code over and over?

like request this in parallel and return the data of all

www.apiurl.com/page=2&content=3
www.apiurl.com/page=3&content=6
www.apiurl.com/page=4&content=9

code here

$strings = array('page'=>'1',                    
                '&content'=>'3');

$postdata = http_build_query($strings);

$data = curl_init();

curl_setopt ($data, CURLOPT_URL, "www.apiurl.com/");
curl_setopt($data, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($data, CURLOPT_POSTFIELDS, $postdata);

$content = curl_exec($data);  
curl_close($data);
print_r($content);

what is the logic, relation between page / content? page is incrementing by 1, and content with 3? — vaso123

Let's give a shot to this...

//Create an array, what stores, what page and what conent you need
$params = array(
    array('page' => 2, 'content' => 3),
    array('page' => 3, 'content' => 6),
    array('page' => 4, 'content' => 9),
    // and so on
);

define('URL', 'www.apiurl.com/');

foreach ($params as $param) {
    $postdata = http_build_query($param, '', '&');
    $data = curl_init();
    curl_setopt($data, CURLOPT_URL, URL);
    curl_setopt($data, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($data, CURLOPT_POSTFIELDS, $postdata);
    $content = curl_exec($data);
    curl_close($data);
    print_r($content);
}

I have tried this code and i am getting just white page .. what might be the cause?

vaso123 Over a year ago

turn on error reporting by error_reporting(E_ALL); and ini_set('display_errors', 1); to inspect what error you you have. But I see what could be wrong. Wait, i will edit my code

try now, but add those 2 lines at the top of your code as I mentioned in my previous comment.
