php - 获取数组中匹配项的键

Question

我正在尝试解决 CSV 报告的问题。我正在尝试根据用户选择的报告中的字符串查找特定信息。它是包含有关许多不同事件和日期的信息的报告（一个事件可能有多个日期，因此每个日期都会重复，导致事件名称多次出现）

用户选择多个表演（特定事件/日期组合），然后使用每个表演的编号将这些表演添加到数组中eventId：

例如

$eventArray = array(232 => 'event one', 21 => 'event four', 443 = 'event one');

每个存在eventid => eventName（可以有重复的事件名称，因为它们在系统中有不同的日期）。

我正在阅读报告，内容如下：

       $file_handle = fopen("$reportUrl", "r");
       while(!feof($file_handle))
        {
           $line_of_text = fgetcsv($file_handle, 20000);
           include('logic/finance_logic.php');                                      
        }
       fclose($file_handle);

因此，对于 CSV 中的每一行，它都在运行finance_logic.php文件中的代码。我遇到困难的部分如下：

// CHECK TO SEE IF THE FIRST LINE IS AN EVENT IN THE ARRAY (NOTE, THERE CAN BE DOUPLICATES)
if(in_array(trim(substr($line_of_text[0],6)), $eventArray)) 
    {
        $f = 1;
        // get event name
        $eventName = trim(substr($line_of_text[0],6));
        // date of event
        $eventDateArray = getEventDateArray($eventName);
    }
    if(isset($f))
        {
            $dateSearch = checkDateInArray($line_of_text[0], $eventDateArray);
            if($f == 1 && $dateSearch[0] == 'found')
                {
                    $eventId = $dateSearch[1];
                    $f = 2;
                }

checkDateInArray功能如下：

function checkDateInArray($date, $array)
{
    if(is_array($array))
        {
            foreach($array as $key => $d)
                {
                    if (strpos($date, $d) !== false) 
                        {
                            // return array with first value 'found' and second being the key which is the event id
                            return array('found', $key);
                        }
                }
        }
}

注意：时间并不总是以格林威治标准时间结尾，因为它取决于位置，因此在比较日期时也需要忽略这一点。

所有这些都会导致对某些事情的混乱修复，我相信另一种方式要简单得多。我正在考虑的一种方法是创建的事件数组是，eventId => eventName但与数据库中的和eventId链接。有没有办法我可以创建一个which was然后检查它是否在这些中。我不知道该怎么做。此外，CSV 的布局方式示例如下：eventNameeventDateeventArrayeventId => array('eventName', 'eventDate')

我做了以下事情：

if(!isset($f))
    {
        $eventDateArray = checkIfEventInArray(trim(substr($line_of_text[0],6)), $eventArray);
    }
if($eventDateArray['result'] == true)
    {
        unset($eventDateArray['result']);
        $f = 1;
        // get event name
        $eventName = trim(substr($line_of_text[0],6));
    }
    if(isset($f))
        {
            if($f == 1 && strpos($line_of_text[0], 'Performance Date:') !== false)
                {
                    $dateCheck = checkIfDateInArray($line_of_text[0], $eventDateArray);
                }
            if($f == 1 && $dateCheck['result'] == true)
                {
                    $eventId = $dateCheck['eventId'];
                    $f = 2;
                }
            if($f == 1 && $line_of_text[0] == 'Abbreviated Performance Totals')
                {
                    unset($f);
                }

使用以下功能：

function selectedEventsArray($array)
    {
        if(is_array($array))
            {
                $editedArray = '"' . implode('","', $array) . '"';
                $eventArray = array();
                $sql = mysql_query("SELECT id_event, name_event, date_event, time_event FROM event WHERE id_event IN ($editedArray)");
                while ($row = mysql_fetch_array($sql))
                    {
                        date_default_timezone_set('Europe/Dublin');
                        $date = date_create($row['date_event']);
                        $for_date = date_format($date,'d M Y');
                        $time = date_create($row['time_event']);
                        $for_time = date_format($time,'h:i A');
                        $eventDate = "Performance Date:  $for_date $for_time";

                        $eventArray[$row['id_event']] = array($row['name_event'], $eventDate);
                    }
                return $eventArray;
            }
    }

function checkIfEventInArray($str, $eventArray)
    {
        $newArray = array();
        $newArray['result'] = false;
        foreach ($eventArray as $key => $i)
            {
                if(trim(strtolower(strip_tags($str))) == trim(strtolower(strip_tags($i[0]))))
                    {
                        $newArray['result'] = true;
                        $newArray[$key] = $i[1];
                    }
            }
        return $newArray;
    }

function checkIfDateInArray($dateStr, $eventDateArray)
    {
        $newArray = array();
        $newArray['result'] = false;
        foreach ($eventDateArray as $key => $i)
            {
                if (strpos($dateStr, $i) !== false)
                    {
                        $newArray['result'] = true;
                        $newArray['eventId'] = $key;
                    }
            }
        return $newArray;
    }
