CURL is a must-have killing medicine for home travel. Why? It is because it is easy to use to achieve the page capture simulation login collection and other 1 series of functions. Remember that the first time you touch CURL, you want to complete fetching from the list of mailbox users. At that time, in order to catch up with the schedule, I did not study carefully. I just found some information on the Internet and realized the function. Now the original code clean 1 function will still work

?>Set up an PHP file to copy and save the above code, the effect will be immediate, remember to change the email account and password, the account does not need the @ suffix. CURL’s first experience, how is it? It’s not bad. Later, I saw another post on CSDN asking a question about getting express query. He wanted to put the query business of some large express companies in one page, which was indeed a very good practical gadget. However, because of the verification code for express query, it reminded me of CURL. Later, I helped the post master to realize the function. The idea was very simple. First, CURL was used to simulate fetching captchas and then displayed in the user submission page.
The source code is as follows: -getEms.html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>EMS Express query </title>
</head>
<body>
<?php
fclose(fopen('cookie.txt','w')); // file cookie.txt Used to store the obtained cookie
$cookiejar = realpath('cookie.txt');
$fp = fopen("example_homepage.txt", "w"); // file example_homepage.txt Used to store the retrieved page content
$ch = curl_init("http://www.ems.com.cn/servlet/ImageCaptchaServlet");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_COOKIESESSION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiejar);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiejar);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
//readfile($cookiejar); // View the fetch cookie
//readfile("example_homepage.jpg"); // View the retrieved image

Using this callback function, the response header information is processed by itself. The response header information is returned on a line. Sets the return value to the length of the string. CURLOPT_READFUNCTION: Callback function with two arguments, the first is the session handle and the second is the string of HTTP response header information. Using this function, the returned data is processed by itself. The return value is the data size. CURLOPT_WRITEFUNCTION: Callback function with two arguments, the first is the session handle and the second is the string of HTTP response header information. Using this callback function, the response header information is processed by itself. The response header is the entire string.
