您好我正在尝试创建一个类似聊天系统的php文件,我可以在其中输入文本,然后将其与之前的条目相呼应。在我的文本文件中,它会在结束时显示,但在使用
时echo file_get_contents("example.txt")
如果在我的txt文件中有另一个选项显示文件,那么文件只会在每行末尾没有中断显示?

尝试这个,我认为它可以根据需要提供输出
echo $string= preg_replace("/\n/", "<br>", file_get_contents('sample.txt'));

代码可能有很多问题。
如果您使用PHP脚本编写文件,请确保使用双引号。这意味着以下正确:

但不是:
<?php fwrite($your_file, "Text to write \n in your file"); ?>
单引号将写入文字字符<?php fwrite($your_file, 'Text to write \n in your file'); ?>
而不是新行,因为单引号通常不会处理您为其提供的字符串。
其次,当您使用\n
读取文件时,您将获得一个不包含\ n等字符的字符串。
PHP文档说
file_get_contents() - 将整个文件读入字符串
因此,要解决此问题,请将字符串包装在file_get_contents("your_file.txt");
标记中,如:
<pre>
<?php echo "<pre>" . file_get_contents("your_file.txt") . "</pre>";
标记输出预先格式化的字符串,这意味着它的确切含义。
希望这有帮助! :)
答案 2 :(得分:0)
PHP Doc说
file_get_contents() - 将整个文件读入字符串
e.g。这会将文件的主体转换为字符串,但是(不可见的等价物)\ n不是字符串char
尝试使用foopen功能。
$handle = fopen("/home/rasmus/file.txt", "r");
