PHP - parsing a txt file
提问by terrid25
I have a .txt file that has the following details:
我有一个 .txt 文件，其中包含以下详细信息：
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
What I'd like to do, is parse this ad get the values into a more readable format, possibly into an array if possible.
我想做的是解析此广告，将值转换为更易读的格式，如果可能，可能转换为数组。
Thanks
谢谢

You can do that easily this way
你可以通过这种方式轻松做到这一点
$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 />';
}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.
首先使用函数打开文本文件file_get_contents()，然后使用函数剪切换行符上的字符串explode()。通过这种方式，您将获得一个所有行都分开的数组。然后使用该功能，array_shift()您可以删除第一行，因为它是标题。
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 $info[0]['description']would be Some text goes here.
获得行后，您可以遍历数组并将所有信息放入一个名为 的新数组中$info。然后，您将能够从第 0 行开始获取每行的信息。所以例如$info[0]['description']将是Some text goes here.
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(',', $info[0]['images']);
如果你也想把图像放在一个数组中，你也可以使用explode()。只需将其用于第一行：$first_row_images = explode(',', $info[0]['images']);

$values = explode('^', $string);
Or, if you want something nicer:
或者，如果你想要更好的东西：
$data = array();
$firstLine = true;
foreach(explode("\n", $string) as $line) {
if($firstLine) { $firstLine = false; continue; } // skip first line
$row = explode('^', $line);
$data[] = array(
'id' => (int)$row[0],
'name' => $row[1],
'description' => $row[2],
'images' => explode(',', $row[3])
);
}

By far the best and simplest example of this I have come accross is quite simply the file() method.
到目前为止，我遇到的最好和最简单的例子就是 file() 方法。
$array = file("myfile");
foreach($array as $line)
{
echo $line;
}
This will display all the lines in the file, this is also applicable for a remote URL.
这将显示文件中的所有行，这也适用于远程 URL。
Simple and clear.
简单明了。

I would like to contribute a file that provides atomic data structures.
我想贡献一个提供原子数据结构的文件。
$lines = file('some.txt');
$keys = explode('^', array_shift($lines));
$results = array_map(
function($x) use ($keys){
return array_combine($keys, explode('^', trim($x)));
},
$lines
);

Try fgetcsv()with ^as the separator character:
尝试fgetcsv()使用^作为分隔符：
$file = fopen($txt_file,"r");
print_r(fgetcsv($file, '^'));
fclose($file);
回答by jwillmer
youse a list, and split the "image_1.jpg,image_2.jpg" after you explode the string:
你使用一个列表，并在分解字符串后拆分“image_1.jpg,image_2.jpg”：
list($number, $status, $text, $images) = explode("^", $data);
$splited_images= preg_split(',', $images);

My solution
我的解决方案
function parseTextFile($file){
if( !$file = file_get_contents($file))
throw new Exception('No file was found!!');
$data = [];
$firstLine = true;
foreach(explode("\n", $file) as $line) {
if($firstLine) {
$keys=explode('^', $line);
$firstLine = false;
continue;
} // skip first line
$texts = explode('^', $line);
$data[] = array_combine($keys,$texts);
}
return $data;
}

<?php
$row = 1;
if (($handle = fopen("test.txt", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, "^")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>

Ok, didn't see the edited version, so here's a redo. It's most likely a CSV file that uses carets as the separator, so...
好的，没有看到编辑的版本，所以这里重做。它很可能是一个使用插入符号作为分隔符的 CSV 文件，所以......
$fh = fopen('yourfile.txt');
$headers = fgetcsv($fh, 0, '^');
$details = array();
while($line = fgetcsv($fh, 0, '^')) {
$details[] = $line;
}
fclose($fh);
