This article describes how to implement http and https requests using php curl. The details are as follows:

Generally, the php curl function group can help us pretend to be an adult and capture the website. Here are two examples: accessing an http webpage and accessing an https webpage, let's take a look.

Each time you use curl, you always need to check a bunch of data.
Now we can save a few frequently used sentences, saving every time we go to Google.

Common curl requests:

The Code is 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:

The Code is 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 focus.
$ Data = curl_exec ($ curl );
Curl_close ($ curl );
Var_dump ($ data );

Note:

When requesting https data, the certificate is required. At this time, the following two parameters are added to avoid ssl certificate check.

The Code is as follows:

Curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https requests do not verify the certificate and hosts
Curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, FALSE );
