在PHP中逐列读取rpt文件内容答案

【问题标题】：Read rpt file content column by column in PHP在PHP中逐列读取rpt文件内容
【发布时间】：2019-05-22 15:22:23
【问题描述】：

我有 .rpt 文件，我需要读取它们的数据，然后将数据存储在 MYSQL 数据库中。我尝试了以下解决方案：

$lines = file("aa.rpt");
echo '<table>';
foreach ($lines as $line_num) {
        $str = trim(htmlspecialchars($line_num));
        echo '<tr>';
        echo '<td>' . getColumnText("/\s([a-zA-Z\s]+)/", $str) .'</td>';
        $secondCol = getColumnText("/\s([0-9]+)/", $str);
        echo '<td>' . $secondCol .'</td>';
        $thirdCol = end(explode(" ", $str));
        if (trim($secondCol) === $thirdCol) {
            echo '<td style="text-align:right">' . str_repeat(" ", 10) .'</td>';
        } else {
            echo '<td style="text-align:right">' . str_repeat(" ", 10) . $thirdCol .'</td>';
        }
        echo '</tr>';

}
echo '</table>';

function getColumnText($pattern, $str) {
    preg_match($pattern, $str, $matches);
    return trim(current($matches));
}

我从 stackoverflow 的另一篇文章中得到了这个代码想法，但是我仍然有两个问题：

我不知道我的文件中可用的列数。它可能因文件而异。
每个文件都包含许多记录，其中在某些记录标题之后再次重复。此外，不同文件之间的标题不一致，因此我无法估计每当标题再次出现时从顶部和内容之间删除的行数。

我在 Notepad++ 中编辑了我作为示例粘贴在这里的文件，但是我不确定是否所有隐藏字符都将按原样复制。

【问题讨论】：

我建议您删除您提供的客户的确切详细信息，因为它可能被用来在互联网上识别他们。
@ammportal 我必须这样做，因为这里的人们需要实际的代码和实际的输出，以便他们能够更好地理解。如果我编辑数据，它可能会改变一些对齐方式。仍在考虑您的评论，我已经更新了详细信息。
感谢您的考虑。你所做的正是我所指的。虚拟数据足以理解和回答您的问题。
不知道列的数量和宽度会很困难。也是因为数据不一致。我想出了this demo at 3v4l.org by manually setting col width （正要回答，但如果文件中的列宽度不同 - 或者您需要针对每个文件进行调整）。
Here a version with autodetect column offsets 从最顶部的标题开始，并根据最左侧的列值向左移动偏移量。希望它有所帮助，但不知道您的数据看起来有多么不同，这只是一个猜测 =D

这样的事情怎么样。

//           SNO     Name   Addr   City   State  Pin    CustId AccNo  Mobiles                     Pan    Scheme DateLoan               Limit  PrAdv  BalOs  BCEntered
$pattern = '/(\d+\s*)(.{37})(.{80})(.{15})(.{20})(.{20})(.{15})(.{21})(.{17})(.{17})(.{17})(.{17})(.{12})(.{12})(\d\d-\d\d-\d\d\d\d\s*)(.{15})(.{26})(.{12})((?:\d\d-\d\d-\d\d\d\d)?)/';

function readAccount($str) {
    if( !preg_match($pattern, $str, $matches) ) return null;
    return array(
            "sno"=>trim($matches[1]),
            "name"=>trim($matches[2]),
            "addr"=>trim($matches[3]),
            //...
    );
}

$lines = file("aa.rpt");
foreach ($lines as $line_num) {
    $str = trim(htmlspecialchars($line_num));
    $account = readAccount($str);
    if( $account)
            saveToDb($account);
}

如果当前处理的行是无效的数据行，readCustomer 将不匹配并返回 null。否则，方法将一一读取信息组，并返回帐户对象。在循环中，如果返回值是一个合法的账号，可以保存到db中。

您好，您的解决方案不起作用。我尝试了以下代码替换来打印您正在获取的内容，它一次只给出一个字符，而不是列数据。 if( !preg_match($pattern, $str, $matches) ) 返回空值；回声修剪（$matches[1][0]）。 “|”。修剪（$matches[2][0]）。 “|”。修剪（$matches[3][0]）。 "
";
抱歉，不是 php 专家，误解了 php 手册中的 $matches 对象。我编辑了答案，它现在应该可以工作了。应该使用 $matches[1] 而不是 $matches[1][0]。
