开发技术学习

在实际操作中我们经常会遇到在某个文件下查找我们想要的某个文件，判断是否存在或统计文件总数量,今天在oschina上看见了这个blob函数快速查询指定目录！这里分享blob的实际运用方法： php查看目录下的所有文件,php blob函数快速查询指定目录文件实例 [php] php教程 blob 函数快速查询指定目录文件实例 //搜索当前目录所有文件 $array = glob('*.*'); print_r($array ); /* Array ( [0] => 1.php [1] => 10.php [2] => 11.php [3] => 2.asp教程 [4] => 3.asp [5] => 4.aspx [6] => 5.html [7] => 6.php [8] => 7.php [9] => 8.php [10] => 9.php ) */ //搜索以.php结果的php文件 $array = glob('*.php'); print_r($array ); /* Array ( [0] => 1.php [1] => 10.php [2] => 11.php [3] => 6.php [4] => 7.php [5] => 8.php [6] => 9.php ) */ //搜索包括有php,aspx 文件 $files = glob('*.{php,aspx}', GLOB_BRACE); print_r( $files ); /* Array ( [0] => 1.php [1] => 10.php [2] => 11.php [3] => 6.php [4] => 7.php [5] => 8.php [6] => 9.php [7] => 4.aspx ) */ //在指定目录搜索以1开的php 文件 $files = glob('../05-15/1*.php'); print_r($files); /* Array ( [0] => ../05-15/1.php [1] => ../05-15/10.php [2] => ../05-15/11.php ) */ //返回文件的绝对路径 $files = array_map('realpath',$files); print_r($files); /* Array ( [0] => D:wwwwww.111cn.net5-151.php [1] => D:wwwwww.111cn.net5-1510.php [2] => D:wwwwww.111cn.net5-1511.php ) glob() 函数能做的事比scandir() 函数更强大，可以按照某种模式搜索文件 */ [/php]
