PHP prompts Call to undefined function curl_init()_PHP tutorial when using curl function

Yesterday, when I was using curl to write an api interface, I found that when running the curl function, I was prompted with a Call to undefined function curl_init() error. Judging from the error, the curl_init() function was not defined. Later I learned that this function requires PHP to be enabled. A file in, the specific method is as follows.

This is how I wrote the program code

//Close URL request curl_close($curl);

The code is as follows

代码如下	复制代码
??php // 初始化一个 cURL 对象 $curl = curl_init(); // 设置你需要抓取的URL curl_setopt($curl, CURLOPT_URL, 'http://www.bKjia.c0m'); // 设置header curl_setopt($curl, CURLOPT_HEADER, 1); // 设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 运行cURL，请求网页 $data = curl_exec($curl); // 关闭URL请求 curl_close($curl); // 显示获得的数据 var_dump($data);

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);

//Set cURL parameters to require the results to be saved in a string or output to the screen. curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

//Run cURL and request the web page

$data = curl_exec($curl);

//Display the obtained data

var_dump($data);

The result prompts: Call to undefined function curl_init(). Later, Baidu provided some solutions for your reference. Modify configuration under windows+apache: 1. Modify php.ini and remove the semicolon in front of ;extension=php_curl.dll 2. Copy the two files libeay32.dll and ssleay32.dll (C:AppServphp5) to the system32 directory

3. Restart Apache (services.msc)

linux+apache solution: The curl package needs to be installed. If you use ubuntu, open the Synaptic package manager, search for curl, and install curl http://www.bkjia.com/PHPjc/632132.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632132.htmlTechArticleYesterday when I was using curl to write an api interface, I found that when running the curl function, it prompted Call to undefined function curl_init() Error, judging from the error, the curl_init() function is not defined, and then...
