PHP-解析txt文件 [英] PHP - parsing a txt file

问题描述

我有一个.txt文件，其中包含以下详细信息:

I have a .txt file that has the following details:

ID^NAME^DESCRIPTION^IMAGES
123^test^Some text goes here^image_1.jpg,image_2.jpg
133^hello^some other test^image_3456.jpg,image_89.jpg

我想做的是解析此广告，以使这些值以更易读的格式，如果可能的话，也可以转换为数组.

What I'd like to do, is parse this ad get the values into a more readable format, possibly into an array if possible.

谢谢

推荐答案

您可以通过这种方式轻松实现

$txt_file    = file_get_contents('path/to/file.txt');
$rows        = explode("\n", $txt_file);
array_shift($rows);

foreach($rows as $row => $data)
{
    //get row data
    $row_data = explode('^', $data);

    $info[$row]['id']           = $row_data[0];
    $info[$row]['name']         = $row_data[1];
    $info[$row]['description']  = $row_data[2];
    $info[$row]['images']       = $row_data[3];

    //display data
    echo 'Row ' . $row . ' ID: ' . $info[$row]['id'] . '<br />';
    echo 'Row ' . $row . ' NAME: ' . $info[$row]['name'] . '<br />';
    echo 'Row ' . $row . ' DESCRIPTION: ' . $info[$row]['description'] . '<br />';
    echo 'Row ' . $row . ' IMAGES:<br />';

    //display images
    $row_images = explode(',', $info[$row]['images']);

    foreach($row_images as $row_image)
    {
        echo ' - ' . $row_image . '<br />';
    }

    echo '<br />';
}

首先使用功能file_get_contents()打开文本文件，然后使用功能explode()在换行符上剪切字符串.这样，您将获得一个数组，其中所有行都分开.然后使用功能array_shift()可以删除第一行，因为它是标题.

First you open the text file using the function file_get_contents() and then you cut the string on the newline characters using the function explode(). This way you will obtain an array with all rows seperated. Then with the function array_shift() you can remove the first row, as it is the header.

获取行之后，可以遍历数组并将所有信息放入名为$info的新数组中.然后，您将能够从零行开始获取每行的信息.因此，例如$info[0]['description']将是Some text goes here.

After obtaining the rows, you can loop through the array and put all information in a new array called $info. You will then be able to obtain information per row, starting at row zero. So for example $info[0]['description'] would be Some text goes here.

如果您也想将图像放入数组中，也可以使用explode().只需在第一行中使用它即可:$first_row_images = explode(',', $info[0]['images']);

If you want to put the images in an array too, you could use explode() too. Just use this for the first row: $first_row_images = explode(',', $info[0]['images']);
