PHP Curl methods to implement HTTP and HTTPS requests _php tips

This article describes the Php Curl implementation of HTTP and HTTPS request method, share for everyone to reference. Specifically as follows:

Generally speaking, PHP's Curl function group can help us to take the machine camouflage adult behavior to crawl the website, below to share two examples, one is accesses the HTTP webpage, one accesses the HTTPS webpage, looks together.

Every time you use curl, you always have to look up a bunch of data.
Now will be used to save a few sentences, the province every time to go to Google.

General Curl Request:

Copy Code code as follows:

$url = ' http://www.jb51.net ';
$curl = Curl_init ();
curl_setopt ($curl, Curlopt_url, $url);
curl_setopt ($curl, Curlopt_header, 1);
curl_setopt ($curl, Curlopt_returntransfer, 1);
$data = curl_exec ($curl);
Curl_close ($curl);
Var_dump ($data);

use Curl to request https:

Copy Code code as follows:

$url = ' https://www.jb51.net ';
$curl = Curl_init ();
curl_setopt ($curl, Curlopt_url, $url);
curl_setopt ($curl, Curlopt_header, 1);
curl_setopt ($curl, Curlopt_returntransfer, 1);
curl_setopt ($curl, Curlopt_ssl_verifypeer, false);//This is the point.
$data = curl_exec ($curl);
Curl_close ($curl);
Var_dump ($data);

Attention

When requesting data for HTTPS, a certificate is required, and the following two parameters are added to circumvent the SSL certificate check

Copy Code code as follows:

curl_setopt ($ch, Curlopt_ssl_verifypeer, FALSE); HTTPS request does not verify certificate and hosts
curl_setopt ($ch, Curlopt_ssl_verifyhost, FALSE);

I hope this article will help you with your PHP program design.
