Question

我从扫描的收据中获取文本字符串。以下是几个例子：

George's Restaurant 300 72th Street Miami Beach fl 33141 305-864-5586服务器：Ronald 01/19/2013表20/1 10:53 PM嘉宾：1 10062转载＃：1法拉利Carano Insalate Cesare Caprese与意大利熏火腿FISH SPEC菠菜意大利乳清干酪馄饨海鲜意大利面Ossobucco 47.00 7.50 9.50 25.95 15.95 19.95 29.95小计总税155.80 14.02总计169.82 169.82余额到期未包括在内！谢谢您的业务

如何确定每种情况下的总金额（169.82和52.88）？

我原以为我可以删除所有非数字字符，将剩余部分拆分为数组并寻找最大数字。但它可能会让地址和电话号码混乱。我想我需要确保单词TOTAL，SUB-TOTAL或AMOUNT DUE附近。

有什么建议吗？感谢。

看来我需要研究神经网络来解决这个问题。

试试这个：

<?php

function checktotal($rcpt) {
    if (preg_match_all('/(\d+\.\d{2})(?:\D|$)/', $rcpt, $match))
        echo 'Total is $' . max($match[1]) . "\n";
    else echo "No numbers!\n";
}

$rcpts = [

foreach ($rcpts as $rcpt) checktotal($rcpt);

测试组的输出是：

Total is $52.88
Total is $87.53
