php数据库中常用的函数 php实现数据库查询( 二 )

IT技术Resolved


以下为引用的内容
// get all php files $files = glob( * php );
print_r($files); /* output looks like: Array ([ ] = phptest php[ ] = pi php[ ] = post_output php[ ] = test php ) */

以下为引用的内容
// get all php files AND txt files $files = glob( * {php txt} GLOB_BRACE);
