Question

我正在尝试从以下字符串/文本中提取金额：

Offerlist: 19939 Product: Technic Time: 13.01.16 - 14:08 Delivery: txt Offer36: 0,00 EUR Offer38: 185€ Best-Offer: 0,00 Offer5: 100 Offer1: 000000 Offer34: 80,00€ Offer5443: 185€ Offer876a: 00 Best-Offer: 200

我试过这个：

if (preg_match("/(?<=Offer1:)(.*?)(?=Offer34:)/s", $output, $result)) {
  $offer = trim($result[0]);
}

但问题是，如果名称或位置发生变化，脚本将不再起作用。

Answer 1

也许你应该搜索价值而不是它的兄弟姐妹。

因此以下脚本应该更好用：

$dates = [];
if (preg_match_all("/(\w+\d*): (\d+(,\d+)?[€]?|\d\d\.\d\d.\d\d \- \d\d:\d\d|\w+)/s", $output, $result, PREG_SET_ORDER)) {
  foreach ($result as $data) {
    $dates[] = [$data[1] => $data[2]];
  }
}

Answer 2

使用preg_match_all（）和非常明确的编程可以这样做：

$string = 'Offer1: 000000 Offer34: 80,00€ Offer5443: 185€ Offer876a: 00 Best-Offer: 200';

$regex = '/((best-)?offer[^:]*:)([ 0-9,€]+)/i';

preg_match_all($regex, $string, $matches);

$offers = [];
for($c = 0; $c < count($matches[1]); $c++) {
  $label = substr($matches[1][$c],0,-1);
  $offers[$label] = trim($matches[3][$c]);
}

var_dump($offers);

输出：

array(5) {
  ["Offer1"]=>
  string(6) "000000"
  ["Offer34"]=>
  string(8) "80,00€"
  ["Offer5443"]=>
  string(6) "185€"
  ["Offer876a"]=>
  string(2) "00"
  ["Best-Offer"]=>
  string(3) "200"
}
