PHP’s simple method to determine whether a string contains another string, php string

The example in this article describes PHP’s simple method to determine whether a string contains another string. Share it with everyone for your reference, the details are as follows:

When using PHP to determine whether a string contains a simple substring, we usually use the two functions strpos() or stristr(), but if the position of the string is in At index 0, that is to say at the beginning of the string to be matched, there will be a problem.

Of course we still have a solution. Here is a stupid solution, but it is easier to use. It applies to both Chinese and English punctuation marks.

The code is as follows:

function checkStr($str,$target)
{
  $tmpArr = explode($str,$target);
  //print_r($tmpArr);
  if(count($tmpArr)>1)return true;
  else return false;
}
$result = checkStr("sdfg","bsdfsldkfj");
var_dump($result);

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
