Read file contents with Laravel
提问by Cheskq
I am trying to read the contents of a file line by line with Laravel. However, I can't seem to find anything about it anywhere.
我正在尝试使用 Laravel 逐行读取文件的内容。但是，我似乎无法在任何地方找到有关它的任何信息。
Should I use the fopen function or can I do it with the File::get() function?
我应该使用 fopen 函数还是可以使用 File::get() 函数？
I've checked the API but there doesn't seem to have a function to read the contents of the file.
我已经检查了 API，但似乎没有读取文件内容的功能。

You can use simple PHP:
您可以使用简单的 PHP：
foreach(file('yourfile.txt') as $line) {
// loop with $line for each line of yourfile.txt
}

You can use the following to get the contents:
您可以使用以下内容来获取内容：
$content = File::get($filename);
Which will return a Illuminate\Filesystem\FileNotFoundExceptionif it's not found. If you want to fetch something remote you can use:
Illuminate\Filesystem\FileNotFoundException如果找不到，它将返回一个。如果你想获取远程的东西，你可以使用：
$content = File::getRemote($url);
Which will return falseif not found.
false如果找不到，它将返回。
When you have the file you don't need laravel specific methods for handling the data. Now you need to work with the content in php. If you wan't to read the lines you can do it like @kylek described:
当您拥有该文件时，您不需要 laravel 特定的方法来处理数据。现在您需要处理 php 中的内容。如果你不想阅读这些行，你可以像@kylek 描述的那样做：
foreach($content as $line) {
//use $line
}
