ThinkPHP learning notes (8) a small example of adding, deleting, modifying, and querying users

ThinkPHP learning notes (8) a small example of adding, deleting, modifying, and querying a user is mainly about how to implement the action File: conf file & lt ;? Php $ selfConfigarray (it is best to delete some ~ App. php and ~ Runtime. php configuration item & gt; the configuration value can be accessed through the original path, for example, ThinkPHP learning notes, because the URL is enabled again, whether it is overwritten or not. (8) A small example of adding, deleting, modifying, and querying users

The main method is to implement the action File:

Conf file

 'Configuration value' // because the URL is enabled again, whether it is overwritten or not, it can be accessed through the original path. // If you want to enable the rewrite mode, perform the following operations // 1. the query server has enabled the Apache rewrite module // LoadModule rewrite_module modules/mod_rewrite.so // 2. create a new one under the statistics Directory of the master Portal file. htaccess (vi: save. htaccess; notepad :". htaccess ") // If you select mode 2 (rewrite), the server will consume more 'URL _ model' => 1, 'URL _ PATNINFO_MODEL '=> 2, // pathinfo contains two classes // 1 Normal mode: m and a: The order relationship can change // http: // localhost/MyThinkPHP/admin. php/m/index/a/index // pass the value // http: // localhost/MyThinkPHP/admin. php/m/index/a/index/username/zhangsan/password // 2 intelligent identification module operation (intelligent identification is the default mode) // http: // localhost/MyThinkPHP/admin. php/index // pass the value // http: // localhost/MyThinkPHP/admin. php/index/username/zhangsan/password // modify the URL separator // 'URL _ pathinfo_depr' => '-', // modify the left and right delimers of the template 'tmpl _ L_DELIM '=>'

Database link files and configurations introduced externally
