Question

我正在尝试创建一个多维数组，但是内部一直使用foreach中数组的最后一个值。

我正在使用PHP 7.3和Laravel 5.8。我试过对该区域进行一次foreach，然后对位置进行一次foreach，在内部对信息进行一次foreach。我正在使用的正则表达式是：

// Define regex for each of the required fields
$location_regex = '/----(.*)-----/m';
$total_regex = '/^.*\bTotal\b.*/m';
$age_regex = '/Age         (?:DAYS       (\d+))/m';
// Perform the regex
preg_match_all($location_regex, $message, $locations, PREG_SET_ORDER, 0);
preg_match_all($age_regex, $message, $ageMatches, PREG_SET_ORDER, 0);
preg_match_all($total_regex, $message, $totalMatches, PREG_SET_ORDER, 0);

然后，当然$ ageMatches和$ totalMatches将作为数组返回。

我正在使用正则表达式从以下纯文本电子邮件中获取值：

我的数据是

    // Go through each message
            foreach ($aMessage as $oMessage) {
                // Get address from email subject
                $address = $oMessage->getSubject(true);

                // Add the address to an array
                $email_data = array($address);

                // Add the sub location to each address in the array
                foreach ($locations as $location) {
                    $email_data[$address][$location[1]] = array();

                    // Add the data to the sub location in the array
                    foreach ($ageMatches as $ageIndex => $age) {
                        $email_data[$address][$location[1]]['Age'] = $age[1];
                    }
                    foreach ($totalMatches as $totalIndex => $total) {
                        $total['Total'] = preg_replace('/[^0-9]/', '', $total);
                        $email_data[$address][$location[1]]['Total'] = $total['Total'][0];
                    }
                }
            dd($email_data);
            }

当前输出为：

array:2 [▼
  0 => "Ely Farm"
  "Ely Farm" => array:10 [▼
    "UNIT 1  PERCH 1" => array:7 [▼
      "Age" => "7"
      "Total" => "3614"
      "Average" => "67"
      "Deviation" => "16"
      "Evenness" => "23"
      "C.V." => "..23.9"
      "Daily Gain" => "8"
    ]
    "UNIT 1  PERCH 2" => array:7 [▼
      "Age" => "7"
      "Total" => "3614"
      "Average" => "67"
      "Deviation" => "16"
      "Evenness" => "23"
      "C.V." => "..23.9"
      "Daily Gain" => "8"
    ]

我希望得到：

array:2 [▼
  0 => "Ely Farm"
  "Ely Farm" => array:10 [▼
    "UNIT 1  PERCH 1" => array:7 [▼
      "Age" => "7"
      "Total" => "3997"
      "Average" => "64"
      "Deviation" => "14"
      "Evenness" => "29"
      "C.V." => "..21.9"
      "Daily Gain" => "9"
    ]
    "UNIT 1  PERCH 2" => array:7 [▼
      "Age" => "7"
      "Total" => "3849"
      "Average" => "73"
      "Deviation" => "17"
      "Evenness" => "29"
      "C.V." => "..23.9"
      "Daily Gain" => "9"
    ]

据我了解，您的正则表达式并未提取所有数据。仅返回最后一次出现的匹配数据。

您的正则表达式使用'm'修饰符。该修饰符表示多行输入。但是正则表达式需要使用'^'和'$'字符指示输入的开始和结束。请参阅Regular Expression Pattern modifiers的文档。
