PHP注意：未定義的索引：致電/var/www/swvx/timedcdr2.php在線72

Question

我在下面的代碼中得到這個錯誤，並且無法找出原因。我認爲它通過兩次$循環，但我不知道爲什麼。任何人都在意給我一個手校對？

PHP公告：未定義指數：調用/var/www/swvx/timedcdr2.php上線72個

謝謝！

edit- 它確實有效;它只是偶爾拋出該錯誤。至少我認爲它有效。我認爲它可能會達到pbx_accountid數組的最後結果，並且不再有更多結果？我要計算它的次數，看看它是否相符。

edit- 是的，每次運行時都會出現20次錯誤，並且有20個帳戶ID。如果沒有更多的呼叫索引，我該如何強制停止它？

更改此

if($result['calls']['call']) { //<====LINE 72 ################################ 

對此

if(isset($result['calls']['call'])) { //<====LINE 72 ################################ 

該通知意味着你正在讀一個不存在的變量。你這樣做是爲了檢查變量是否存在。有一個函數可以檢查變量是否存在，但不嘗試讀取它，isset。
