如何將這個php slugify函數改寫爲mysql？

我發現這個slugify功能在這裏：PHP function to make slug (URL string)如何將這個php slugify函數改寫爲mysql？

我試着將它改寫到MySQL，那就是我所做的就是：https://techras.wordpress.com/2011/06/02/regex-replace-for-mysql/

和音譯功能：

借用regex_replace功能from：http://igstan.ro/posts/2009-02-13-mysql-transliteration-function.html
重寫了上面提到的從symfony fw到mysql的最後一位創建函數，函數的正確答案函數。

，但在輸出我只得到降低文本，沒有破折號和字母似乎也音譯，所以只剩下的東西是破折號。

我的查詢：

UPDATE `ad_kategorija` SET `slug_lt`=slugify(`kat_pavlt`), `slug_ru`=slugify(`kat_pavru`), `slug_en`=slugify(`kat_paven`)

功能：

所以有人可以幫我完成它，主要的問題是我沒有得到的空間替換了，也許正則表達式是錯誤的破折號。或者正則表達式替換函數需要一些插件來做到這一點。請幫忙。

出於好奇，你爲什麼要在MySQL中做到這一點？ – Mjh

@Mjh，所以我不需要編寫一個寫模塊，它將佔用10個表中的大塊，將其放入數組，然後將其轉換爲另一個非常需要資源的資源，然後將其放回到mysql中。我想這將是更容易宣佈這些功能，只是運行簡單的更新命令來重寫讓我們說的頁面標題slu。。所以你不需要手動改變每個頁面。或運行一些自定義的PHP數據庫更新程序腳本。希望這能滿足你的好奇心。它主要用於通過控制檯更改大規模數據庫。可以說，我的客戶決定在這個項目上獲得seo網址。解釋呢？ – juslintek

嗯，我很佩服你的奉獻精神，我會滿意PHP功能並通過它運行。即使在10萬條記錄中，它仍然能夠在一分鐘左右內完成。我只是想知道，因爲你花了相當一段時間在這方面，我通常太懶惰這樣的事情，喜歡更快的解決方案:) – Mjh

固定我的功能，去除regex_replace使用和替代使用功能從這裏開始：mySQL Stored Function to create a slug

加音譯的調整，最終的代碼是在這裏。音譯功能不變：

P.S.有人在聊天中詢問測試場景。您至少需要一張帶有2個varchars（255）列的表格。以及來自任何書籍或文本的句子，包含逗號，點號，括號，其他識別符號等。由於結果只有數字，單詞，字母和單個破折號必須保留。但是當我開始的時候，結果是空格的小寫字母。
