	$file=fopen("test_files1.txt","r+");
	//$file1=fopen("test_files2.txt","r") or exit("unable to open file!");
	//fclose($file1);
	/*
	下面的代码是逐行读取文件的代码,
	feof:判定是否读到了文件结束标志
	fgets:逐行读取文件
	*/
	while(!feof($file))
	{
		echo fgets($file)."<br/>";
	}
	/*
	字数判定;
	*/
	$file1=fopen("test_files1.txt","r");
	while(!feof($file1))
	{
		if(fgetc($file1)!=' ')
		$num_of_char++;
