file
(PHP 3, PHP 4 >= 4.0.0)file -- 读取整个文件到数组描述
array file (string filename [, int use_include_path])
除了file()返回的是数组,其它的与网站建设服务器脚本类\PHPPHP用户手册fancyfunction.readfile.html>readfile()一样。数组的每个元素对应文件的每一行,而带有换行符。
注意:在结果数组中的每行包含着行结尾,如果你不想要行结尾你可使用trim() 函数去掉它。
如果你想在包含路径中搜索文件,你可以使用可选的第二个参数并把它设置为"1"。
Line $line_num:; ", htmlspecialchars ($line), "
";}// 获得一个网页到字符串中$fcontents = join (, file (http://www.php.net/));?>
警告
这个函数不能用于二进制!
提示:如果"fopen wrappers"配置已经打开,你可以在这个函数中使用 URL 作为文件名。
参见readfile(), fopen(), fsockopen(), 和 popen().
