PHP is a simple way to get string matching content like regular

A simple way to get string matching content is simple, easy to use, and limited in functionality

Note: See Code start Comment, there is not clear place, you can leave a message to me, welcome to the wrong, provide a good way

This example takes the http://www.3444.cc/List/List_4.htm to get the content page address for example

<?php/* Function canshujiequ ($yuanma, $CANSHUSTR, $mubiao) Description: function: Similar to get content, function is simple, can be said to be a small part of regular function but often use the function, is to implement the wildcard and custom way to get the matching content, put in the array parameter description: $yuanma-----The string from which to get the content; $canshustr-----According to the $yuanma Reed content rule, set the string: You can use the wildcard character (*), including the parameter The],[parameter is the required information extracted, $mubiao---------The combination of strings, similar to the engine collector's custom setting method, this function is also the reference locomotive that part of the set implementation method: Constant query matching location, to a unit, after acquiring, 
The string query starts the query after moving to the device until the end of the string returns the type: array containing the matched string/set_time_limit (0);
