php代码执行的一些操作

php列目录

• 利用glob函数

  foreach (glob("./*") as $filename) {  echo $filename."<br>"; }

  The glob() function searches for all the pathnames matching pattern according to the rules used by the libc glob() function, which is similar to the rules used by common shells.
• 利用DirectoryIterator对象

  $d=new DirectoryIterator("glob:///var/www/html/f*");var_dump($d);

• 使用scandir()

  $dir="./";$file=scandir($dir);print_r($file);

  php读文件

• highlight_file()

  $a = highlight_file('flag');
  echo $a;

• show_source()

  show_source("flag.txt");
