问题描述

我有txt文件，它的内容是这样

I have txt file its content like this

Hello  
World   
John  
play  
football  

阅读此文本文件时我想删除换行符，但我不知道它的外观 文件.txt及其编码为utf-8

I want to delete the new line character when reading this text file, but I don't know how it look like the file .txt and its encoding is utf-8

推荐答案

只需将file函数与FILE_IGNORE_NEW_LINES标志一起使用.

Just use file function with FILE_IGNORE_NEW_LINES flag.

file读取整个文件，并返回包含所有文件行的数组.

The file reads a whole file and returns an array contains all of the file lines.

默认情况下，每行末尾都包含换行符，但是我们可以通过FILE_IGNORE_NEW_LINES标志强制进行修剪.

Each line contains new line character at their end as default, but we can enforce trimming by FILE_IGNORE_NEW_LINES flag.

所以这很简单:

$lines = file('file.txt', FILE_IGNORE_NEW_LINES);

结果应为:

var_dump($lines);
array(5) {
    [0] => string(5) "Hello"
    [1] => string(5) "World"
    [2] => string(4) "John"
    [3] => string(4) "play"
    [4] => string(8) "football"
}
