我一直在嘗試下面的腳本(在一個更大的應用程序,我正在工作)現在幾個小時,我只是不明白什麼是問題,不管我得到什麼「注意:Undefined offset:1」,這意味着它有一些問題將結果放入preg_match的數組中......我做了一個與之前的類似頁面幾乎相同的進程,並且它工作正常。我非常感謝任何建議,因爲我現在不知道該怎麼做,因爲我已經花了幾個小時試圖解決這個問題,我沒有大量的正則表達式的經驗,但我已經使用了它很多,而我只是無法弄清楚什麼可能會阻止它正常工作。嘗試使用preg_match提取html頁面,但這是令人困惑的我

我看你的代碼格式掙扎......嘗試選擇你的代碼,然後點擊「代碼」按鈕。 – greg0ire 2010-06-29 10:10:55
Rick,我突出顯示了你的代碼,並在編輯器中點擊了格式化按鈕。這並不完美(看起來像你試圖手動縮進每行4個空格,但錯過了一對),但它是可讀的。此外,眨眼標籤從哪裏來? – 2010-06-29 11:00:35
