[程序语言] PHP

[功能描述] 该脚本从一个指定目录中读取文件名，之后把这些文件名返回到数组中，还包括文件个数。

源代码如下：

＜? /* This script read the filenames from a specified directory and returns them in an array. The number of filenames is also returned. Copyleft(L) 1999 Eric Persson, eric@persson.tm, http://www.persson.tm/scripts/ */ Function searchdir($basedir) { global $filelisting, $number; //defines the two variables as global so they can be accessed from outside the function unset($filelisting); //kills $filelisting in case it have been used earlier in the script unset($number); //same as above $handle=opendir($basedir); while ($file = readdir($handle)) { if ($file=="." or $file=="..") { } else { $filelisting[]="$basedir$file"; }; }; $number=sizeof($filelisting); //gets the size of the array }; searchdir("./"); //runs the function to search the current directory echo $filelisting[1]; //echos the second value in the array echo $number; //echos the size of the array ?＞
