If you run CURLOPT_FOLLOWLOCATION in PHP and then get the php prompt error message:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…
Error Mentioning the two key words safe_mode and open_basedir, if you are a virtual host and do not have permission to set APPCHE, you cannot solve the problem by modifying the server configuration. Generally speaking, the server configuration safe_mode is off, and then there are some security requirements for users. Restriction, by setting open_basedir to limit the PHP execution folder of the virtual host user, so when you use CURLOPT_FOLLOWLOCATION (php curl function, deep capture data), the error message mentioned in the article will appear once there is a 301 redirect, etc.
After checking the relevant information, I quickly found the solution, http://www.php.cn/php-weizijiaocheng-362563.html. These methods are all available in the official php help.
The specific method is in curl Whether to use curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) in the statement, customize a function in the php function,
The code is as follows:
function curl_redir_exec($ch,$debug="") { static $curl_loops = 0; static $curl_max_loops = 20; if ($curl_loops++ >= $curl_max_loops) { $curl_loops = 0; return FALSE; } curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); $debbbb = $data; list($header, $data) = explode("\n\n", $data, 2); $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($http_code == 301 || $http_code == 302) { $matches = array(); preg_match('/Location:(.*?)\n/', $header, $matches); $url = @parse_url(trim(array_pop($matches))); //print_r($url); if (!$url) { //couldn't process the url to redirect to $curl_loops = 0; return $data; } $last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL)); /* if (!$url['scheme']) $url['scheme'] = $last_url['scheme']; if (!$url['host']) $url['host'] = $last_url['host']; if (!$url['path']) $url['path'] = $last_url['path'];*/ $new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:''); curl_setopt($ch, CURLOPT_URL, $new_url); // debug('Redirecting to', $new_url); return curl_redir_exec($ch); } else { $curl_loops=0; return $debbbb; } }
After the function is defined, replace the statement curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) with curl_redir_exec($ch)
After this, I think your PHP file should not prompt an error. Regarding this code, you can find it in the official PHP connection.
The official code of PHP is as follows
/safe 模式不能curl的函数 function curl_redir_exec($ch) { static $curl_loops = 0; static $curl_max_loops = 20; if ($curl_loops++ >= $curl_max_loops) { $curl_loops = 0; return FALSE; } curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); list($header, $data) = explode("\n\n", $data, 2); $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($http_code == 301 || $http_code == 302) { $matches = array(); preg_match('/Location:(.*?)\n/', $header, $matches); $url = @parse_url(trim(array_pop($matches))); if (!$url) { //couldn't process the url to redirect to $curl_loops = 0; return $data; } $last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL)); if (!$url['scheme']) $url['scheme'] = $last_url['scheme']; if (!$url['host']) $url['host'] = $last_url['host']; if (!$url['path']) $url['path'] = $last_url['path']; $new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:''); curl_setopt($ch, CURLOPT_URL, $new_url); debug('Redirecting to', $new_url); return curl_redir_exec($ch); } else { $curl_loops=0; return $data; } } //end

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
