我有以下數組，我需要刪除鍵 83 之前的所有值，值為 BEGIN:VEVENT。我需要的不是按鍵，而是僅使用值。 Array ( [75] => END:DAYLIGHT [76] => BEGIN:STANDARD [77] => DTSTART:20211031T030000 [78] => TZOFFSETFROM:+0300 [79] => TZOFFSETTO:+0200 [80] => TZNAME:EET [81] => END:STANDARD [82] => END:VTIMEZONE [83] => BEGIN:VEVENT [84] => SUMMARY: [85] => DESCRIPTION: Tourist Agent Office: First Name: Last Name: Email: xxx@gma [86] => il.com Visitors: 1 Phone: Details: Time Slots: 12:00 μμ - 11:59 πμ [87] => [88] => DTSTART:20200711T120001 [89] => DTEND:20200725T115902 [90] => UID:2020-07-11 12:00:[email protected] [91] => DTSTAMP:20200604T130218 [92] => CREATED:20200129T104306 [93] => LAST-MODIFIED:20200129T104306 [94] => STATUS:CONFIRMED [95] => END:VEVENT [96] => BEGIN:VEVENT [97] => SUMMARY: [98] => DESCRIPTION: Tourist Agent Office: First Name: Last Name: Email: xxx@gma [99] => il.com Visitors: 1 Phone: Details: Time Slots: 12:00 μμ - 11:59 πμ [100] => [101] => DTSTART:20200912T120001 [102] => DTEND:20200926T115902 [103] => UID:2020-09-12 12:00:[email protected] [104] => DTSTAMP:20200604T130218 [105] => CREATED:20200203T060059 [106] => LAST-MODIFIED:20200203T060059 [107] => STATUS:CONFIRMED [108] => END:VEVENT [109] => END:VCALENDAR [110] =>)到目前為止我已經嘗試過...$result = array_slice($array, array_search('BEGIN:VEVENT', $array) ?: 0);
print_r($array);其中 $array 是上面的例子這將返回相同的數組

$result = array_slice($data, array_search('BEGIN:VEVENT', array_values($data)) ?: 0);
var_dump($result);
函數array_search搜索 的第一次出現BEGIN:VEVENT并返回找到的偏移量，用array_values識別原始數組的值。您可以將此鍵用作array_slice函數的偏移量，該函數返回數組的其余部分。
如果BEGIN:VEVENT給定數組中不存在，則將返回整個數組。
上述示例的結果：
array(27) {
? ? [0] => string(12) "BEGIN:VEVENT"
? ? [1] => string(8) "SUMMARY:"
? ? [2] => string(72) "DESCRIPTION: Tourist Agent Office: First Name: Last Name: Email: xxx@gma"
