Yesterday when I was using curl to write an API interface, I found that when I ran the Curl function, I was prompted by the call-to-undefined function curl_init () error, which, from the wrong point of view, did not define CURL_INIT (). It was later learned that this function must open a file in PHP, as follows.

Program code that's what I wrote.

The code is as follows Copy Code

?? Php
Initialize a CURL object
$curl = Curl_init ();

Set the URL you need to crawl
curl_setopt ($curl, Curlopt_url, ' http://www.bKjia.c0m ');

Set Header
curl_setopt ($curl, Curlopt_header, 1);

Sets the curl parameter, which requires the result to be saved to a string or output to the screen.
curl_setopt ($curl, Curlopt_returntransfer, 1);

Run Curl, request a Web page
$data = curl_exec ($curl);

Close URL Request
Curl_close ($curl);

Show the data obtained
Var_dump ($data);

The results suggest: call to undefined function curl_init (), and then Baidu a number of solutions, we can refer to.
