This article describes how to use PHP to realize the sharing of user-defined functions hidden by asterisks (*) for four digits in the middle of a mobile phone number. this is a common function. For more information, see Php shields four phone numbers in the middle: The code is as follows: Method 1:Function hidtel ($ phone ){$ IsWhat = preg_match ('/(0 [0-9] {2, 3} [\-]? [2-9] [0-9] {6, 7} [\-]? [0-9]

PHP uses non-recursive algorithms to implement first-order, middle-order, and post-order traversal of Binary Tree operation examples. Recursive Binary Tree This example describes how PHP uses non-recursive algorithms to traverse Binary Trees in ascending, central, and descending order. We will share this with you for your reference. The details are as follows: Overview: The principle of binary tree traversal is as follows: For binary tree traversal:

PHP uses the regular expression to replace the display function with an asterisk (*) for the four digits in the middle of the phone number. Because the customer needs to maintain privacy, the mobile phone number cannot be completely displayed on the website, but it cannot be displayed, so many websites think of display but not complete display, in fact, it is very easy to use the asterisk to replace the display part with a regular expression. Meth

The "many-to-many" feature of the graph makes the diagram difficult to implement in terms of structure design and algorithm implementation, then it is necessary to convert the graph to different tree according to the application to simplify the problem solving.One, spanning tree and minimum spanning tree 1.1 spanning treeFor an undirected graph, a minimal connected sub-graph with all the vertices of the connected graph becomes the spanning tree (Spanning trees). The essence is the edge of the tr

Unity3d in the middle of a single caseUsing static classes, the disadvantage of static variables is that from the program loaded after the memory has been occupied, want to release more trouble, but the previous use of the Singleton, did not provide the method of release, it is also the same as static until the end of the program to release the dish? What are the benefits of that single case?In this case, a release method is added to facilitate the re

host M (IP_M, MAC_M) wants to change the flow of data between host A (IP_A, MAC_A) and host S (IP_S, MAC_S) in the same LAN, then host M only needs to send ARP response packets to host A at A fixed interval: "I am IP_S, and my MAC address is MAC_M. ", Send ARP response packets to host S:" I am IP_A, and my MAC address is MAC_M .". In this way, host A will send the data that should have been delivered to host S to host M, and host S will also. To ensure that the communication between host A and
