fopen
$fp = fopen("download.php","rb"); while(!feof($fp)){ echo "fopen: ".fgets($fp); } fclose($fp);
说明:
对于fgets($handle,$length);
fgets是读取一行,返回$length-1长度的数据。
fgetc($handle)是读一个字节。
file
$lines = file("download.php"); foreach($lines as $line){ echo "file: ".$line; }
file_get_contents
$content = file_get_contents("download.php"); echo "get_contents: ".$content;
readfile 据说readfile是不占php线程本身内存的。
echo "readfile: "; readfile("download.php"); flush();
