PHP中實現增刪改查的方法通常是通過使用數據庫操作語言SQL來實現的。常用的數據庫操作語句包括：
示例：INSERT INTO table_name (column1, column2, column3, …) VALUES (value1, value2, value3, …);
示例：DELETE FROM table_name WHERE condition;
示例：UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;
示例：SELECT column1, column2 FROM table_name WHERE condition;
