如何在php中包含文件范围的行? [英] How do I include a range of lines of a file in php?

问题描述

我知道这:

    <?php

$file2 = file('website/files/myfolder/file.html');

echo $file2[8];
echo $file2[9];
echo $file2[10];
echo $file2[11];


?>

将为我提供file.html文件中第8、9、10、11行的内容，但是我希望在第23至116行之间执行约100行.echo $ file2 [NUMBER];一百倍?

would give me the contents on lines 8,9,10,11 in the file.html file, however I would like to do this for about 100 lines ranging from lines 23 to 116. How would I accomplish this without using the echo $file2[NUMBER]; one hundrend times?

解释我要做什么的另一种方式可能是，如果我可以在php中做到这一点:

Another way to explain what I am trying to do would be possibly if I could do this in php:

echo $ file2 [23-116];

显然这是行不通的，但这就是概念.

obviously this will not work but that is the concept.

感谢您的帮助！

推荐答案

使用类似这样的循环

$data = file('website/files/myfolder/file.html');
for ($i = 23; $i <= 116; $i++) {
    echo $data[$i];
}

或者您可以拼接数据:

$data = file('website/files/myfolder/file.html');
echo implode(PHP_EOL, array_splice($data, 23, 116 - 23));
