PHP curl CURLOPT_RETURNTRANSFER parameter usage example, curl example

Get the page content, do not output it directly to the page, CURLOPT_RETURNTRANSFER parameter setting

Use PHP curl to obtain page content or submit data. Sometimes you want the returned content to be stored as a variable instead of output directly. At this time, you must set curl's CURLOPT_RETURNTRANSFER option to 1 or true.

1. Curl gets the page content and outputs it directly. Example:

Copy code The code is as follows:

$url = 'http://www.bkjia.com';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_exec($ch);
curl_close($ch);
?>

2. Curl gets the page content without outputting it directly. Example:

Copy code The code is as follows:

$url = 'http://www.bkjia.com';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch); //The content has been obtained but has not been output to the page.
curl_close($ch);
echo $response;
?>
