Examples of using php curl encapsulation class

Before using the function, we need to open the php curl module (libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

Steps to open the php curl function library

 1). Remove the ;extension=php_curl.dll in the windows/php.ini file; /*Use echo phpinfo(); to view the path of php.ini*/

 2). Copy php5/libeay32.dll and ssleay32.dll to the system directory windows/

 3). Restart apache

php curl

The code is as follows

include_once('curl.class.php');
$aa =new Curl('');
$curlOptions = array(
CURLOPT_URL => "http://ww.ww.ww/addTicket.jsp", //Access URL
CURLOPT_RETURNTRANSFER => true, //Get the result and return it as a string
CURLOPT_REFERER => "ww.ww.ww/zw2",
CURLOPT_HTTPHEADER => array('X-FORWARDED-FOR:139.197.14.19', 'CLIENT-IP:127.0.0.1','Proxy-Client-IP:139.197.14.19','WL-Proxy-Client-IP:139.197 .14.19' ),
CURLOPT_HEADER => 1, //Get the return header information

//CURLOPT_SSL_VERIFYPEER => false, //Support SSL encryption
CURLOPT_POST => true, //Send with POST parameters
CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //Requested POST parameter string
CURLOPT_TIMEOUT => $aa->timeout //Time to wait for response
);
echo $aa->getResponseText($curlOptions);

How to get the current session ID in PHP? How to get the current session ID in PHP? Jul 13, 2025 am 03:02 AM

The method to get the current session ID in PHP is to use the session_id() function, but you must call session_start() to successfully obtain it. 1. Call session_start() to start the session; 2. Use session_id() to read the session ID and output a string similar to abc123def456ghi789; 3. If the return is empty, check whether session_start() is missing, whether the user accesses for the first time, or whether the session is destroyed; 4.

Make sure that the session is correctly enabled and the ID can be obtained successfully.

PHP get substring from a string PHP get substring from a string Jul 13, 2025 am 02:59 AM

To extract substrings from PHP strings, you can use the substr() function, which is syntax substr(string$string,int$start,?int$length=null), and if the length is not specified, it will be intercepted to the end; when processing multi-byte characters such as Chinese, you should use the mb_substr() function to avoid garbled code; if you need to intercept the string according to a specific separator, you can use exploit() or combine strpos() and substr() to implement it, such as extracting file name extensions or domain names.

How to split a string into an array in PHP How to split a string into an array in PHP Jul 13, 2025 am 02:59 AM

In PHP, the most common method is to split the string into an array using the exploit() function. This function divides the string into multiple parts through the specified delimiter and returns an array. The syntax is exploit(separator, string, limit), where separator is the separator, string is the original string, and limit is an optional parameter to control the maximum number of segments. For example $str="apple,banana,orange";$arr=explode(",",$str); The result is ["apple","bana

JavaScript Data Types: Primitive vs Reference JavaScript Data Types: Primitive vs Reference Jul 13, 2025 am 02:43 AM

JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.

Using std::chrono in C Using std::chrono in C Jul 15, 2025 am 01:30 AM

std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)
