It was because of the use of Base64 that the problem occurred when the token was sent through the Get method. For example: http://test/test.php?a=1+2 You use $_get["a" to obtain is: 1 2, namely that the plus sign is gone. At first I used UrlEncode to convert it, but there were always one or two results that were unexpected. Later think of Base64 characters are limited to: [a-za-z0-9\+\/=] So many, plus the problem, I will replace the plus sign without problems, underline is the best choice. Her

Pack them into a file and call it fun.php. Copy Code code as follows: function Passport_encrypt ($txt, $key) { Srand (Double) microtime () * 1000000); $encrypt _key = MD5 (rand (0, 32000)); $ctr = 0; $tmp = '; for ($i = 0; $i $ctr = $ctr = = strlen ($encrypt _key)? 0: $ctr; $tmp. = $encrypt _key[$

This article describes the encryption and decryption function in PHP and DES encryption and decryption application, share for everyone to reference. Specifically as follows: Examples, examples of PHP encryption decryption Cryptographic functions: Copy Code code as follows: /* * Function: Encrypt string to handle * Parameter one: Content that needs to be encrypted * Parameter two: key */ function Passport_encrypt ($STR, $key) {//cryptographic functions Srand (Double)

session_id, You can judge this submission as an external submission. How do I match an action to be performed? In the token, to the token of the action name into this token, so, in processing, the action to solve the comparison on the line. The Gtoken I wrote earlier could not reach the second one mentioned above, and I modified it today to add the function 2. Personal feeling is OK. Please see the code, feel where there is unreasonable place, please enlighten me! Thank you. Encryption I w

in the token is not equal to the current session_id theoretically during submission, you can determine that this submission is an external commit.How to match the action to be executed?During the token operation, you need to write the token action name into the token. in this way, you can parse the action and compare it during processing.The GToken I wrote earlier cannot reach the second one mentioned above. I modified it today and added function 2. I personally feel that it is okay.Let's take

The article introduced about PHP custom encryption and decryption, many friends are with PHP, if we write a will do, the following look at the code.

First find the center of the tree or center, I am here to find the center, because we need to find a same starting point, and then up to 2 centers is the width of the tree is even when the odd time is 1.After finding the tree to hash, so that each point is unique, so that the shape of the tree can be guaranteed unique, and then use the hash value, the tree node under each node to sort, and then if the two trees are the same, I only need to do a deep search of the tree and the order of traversal
