制表符分隔的字符串，使用PHP转换为XML [英] tab-delimited string to XML with PHP

问题描述

我正在尝试像这样将变量的制表符分隔内容写入XML:

I'm trying to write the tab-delimited content of a variable to XML like this:

$tsvData = str_getcsv($input, "\t");
foreach($tsvData as $line => $row) {
    if($line > 0) {
        $xmlWriter->writeElement('NAME', $row[0]);
        $xmlWriter->writeElement('CAKE', $row[1]);
        $xmlWriter->writeElement('BODYPART', $row[2]);
    }
}

但是，每个XML标签只写一个字符，而不是每个标签之间写所有字符.当我使用SplFileObject时，从文件中获取相同的tsv数据，它可以工作.我的str_getcsv函数怎么了?

But it's only writing one character per XML tag instead of everything between each tab. When I use SplFileObject, geting the same tsv data but from a file, it works. What am I doing wrong with the str_getcsv function?

谢谢

推荐答案

str_getcsv()函数返回一维数组，但是您将其视为返回二维数组.

The str_getcsv() function returns a 1-dimensional array, but you're treating it like it's returning a 2-dimensional array.

为澄清起见，str_getcsv()没有线"的概念.而不是这样做:

To clarify, str_getcsv() has no concept of "lines". Instead of doing this:

$tsvData = str_getcsv($input, "\t");

以为您将获得一个由线组成的数组，每行包含一个列数组，您必须执行以下操作:

Thinking that you'll get an array of lines, each one containing an array of columns, you have to do something like this:

$lines = explode("\n", $input);
$tsvData = array();
foreach ($lines as $line) {
    $tsvData[] = str_getcsv($line, "\t");
}
// now $tsvData is a 2-dimensional array of lines/columns like you were wanting
