爲什麼我會得到這些PHP警告：simplexml_load_string

Question

我在寫一個jQuery翻譯插件。我的第一次迭代傳遞了一串字符串來轉換。雖然這工作得很好，但速度非常慢。我修改了插件一次傳遞一個單詞。這兩個例程都使用ajax來調用下面顯示的PHP Translate函數。我已經檢查確保ajax調用正在工作並正確傳遞這些單詞。我也檢查了有關警告的答案，但無濟於事。

翻譯完第一個單詞後，我得到以下消息，爲每個單詞重複。我也收到了一些curl錯誤，抱怨它無法連接到主機（Translate-Exception：curl =無法連接到主機），經過多次警告。

似乎有某種計時問題，但我不能確定它。希望在那裏有人遇到過類似的問題，並且可以對這種痛苦的情況有所瞭解。

爲了解決這個問題，我決定用JavaScript代替PHP重寫翻譯。它現在比PHP版本快得多。
