關於preg_replace()函數文法

preg_replace函數基礎與執行個體代碼
//preg_replace ( mixed $pattern , mixed $replacement , mixed $subject [, int $limit = -1 [, int &$count ]] ) 主題為匹配搜尋模式，替換替換
/*
要搜尋的模式。它可以是一個字串或一個字串數組。

電子修飾符使preg_replace函數（）替代治療後，適當引用作為參數是php教程代碼進行替換。提示：請確保置換構成一個有效php代碼字串，否則php將抱怨在包含preg_replace函數線（）解析錯誤。

傳回值

preg_replace函數（）返回一個數組，如果這個問題的參數是一個數組或一個字串，否則。

如果找到匹配，新問題會產生，否則將返回主題不變或null如果發生錯誤。
