本代码演示了php中如何通过glob查找指定的文件
$dir = './'; foreach(glob($dir.'*.txt') as $file) { print $file . "\n"; } /* returns: ./dummy.txt ./foo.txt ./ideas.txt ./robots.txt ./scite.txt */ /* ** other examples: */ // also possible: $files = glob('*.*'); sort($files); // This shows how to use the GLOB_BRACE flag: $images = glob("images/{*.jpg,*.gif,*.png}", GLOB_BRACE); print_r($images); /* Valid flags: GLOB_MARK GLOB_NOSORT GLOB_NOCHECK GLOB_NOESCAPE GLOB_BRACE GLOB_ONLYDIR GLOB_ERR see PHP.net manual for more info */
