Bài học tiếp theo Hướng dẫn PHP

PHP đi kèm với rất nhiều hàm để làm việc với chuỗi. Bạn có thể sử dụng các hàm PHP tích hợp này để cắt chuỗi, nối hoặc thay thế chúng. Bản thân các hàm chuỗi trong PHP khá mạnh mẽ. Bạn có thể sử dụng chúng để thực hiện các thay đổi không phân biệt chữ hoa chữ thường hoặc thực hiện nhiều thay thế cùng một lúc. Tuy nhiên, họ vẫn yêu cầu bạn chỉ định chính xác chuỗi mà bạn muốn thay thế

Đôi khi, điều đó là không đủ. Bạn sẽ gặp rất nhiều tình huống trong đó những sự thay thế và kết hợp này phải dựa trên một mẫu thay vì một số chuỗi cụ thể. Đây là nơi các biểu thức chính quy đóng một vai trò rất quan trọng

Trong hướng dẫn này, bạn sẽ học cách khớp, tìm kiếm và thay thế chuỗi bằng biểu thức chính quy trong PHP

Hãy bắt đầu với việc tìm kiếm một trận đấu

727 với nhiều chuỗi mà chúng tôi muốn thực hiện thay thế trong đó. Như bạn có thể thấy, tất cả các thay thế được áp dụng cho từng đoạn văn bản riêng lẻ

Sử dụng Some textSome more text735 để tìm kiếm và thay thế bằng các hàm gọi lại trong PHP

Trong phần trước, chúng ta đã thấy các biểu thức chính quy có thể mạnh mẽ như thế nào để thay thế các chuỗi khớp với một mẫu cụ thể. Chúng tôi thậm chí có thể sử dụng các nhóm chụp để sử dụng lại kết quả phù hợp mà chúng tôi đã tìm thấy ở một nơi khác trong chuỗi thay thế

Đôi khi, chúng tôi thậm chí còn cần nhiều quyền kiểm soát hơn thế để sửa đổi nhóm chụp khi chúng tôi thấy phù hợp trước khi thực hiện bất kỳ thay thế nào. Sử dụng hàm

Chúng tôi đã thay thế tất cả các số điện thoại khác nhau bằng một địa chỉ email duy nhất trong tất cả các ví dụ của chúng tôi cho đến nay. Tuy nhiên, nhiều khả năng một công ty có các số điện thoại khác nhau cũng sẽ có các địa chỉ email chuyên dụng khác nhau. Hàm

Trong ví dụ này, mỗi thành viên trong nhóm có một số điện thoại khác nhau và chúng tôi phải thay thế số điện thoại này bằng tổ hợp số điện thoại và địa chỉ email. Điều này có thể được thực hiện rất dễ dàng với

Some text
Some more text

735

Chúng tôi bắt đầu bằng cách xác định chức năng riêng của chúng tôi

Some text
Some more text

739, lấy

Some text
Some more text

740 làm đầu vào của nó. Mảng

Some text
Some more text

740 giống với mảng mà chúng ta đã thảo luận khi nói về

Some text
Some more text

713. Phần tử đầu tiên trong

Some text
Some more text

740 sẽ là toàn bộ kết quả khớp và các phần tử khác sẽ chứa các mẫu con tiếp theo

Biểu thức chính quy trong mẫu của chúng tôi chứa hai nhóm chụp để lấy tên và số điện thoại làm các phần tử riêng biệt. Chúng tôi sử dụng tên của người đó để lấy địa chỉ email của mình bằng cách chuyển đổi nó thành chữ thường bằng cách sử dụng

Some text
Some more text

744 và sau đó nối thêm

Some text
Some more text

745. Cuối cùng, chúng tôi trả lại văn bản thay thế mới của mình

Phiên bản mới hơn của chuỗi chính của chúng tôi hiện chứa cả số điện thoại và địa chỉ email của nhân viên

Sử dụng Some textSome more text746 để tách chuỗi trong PHP

Hàm

Some text
Some more text

747 rất hữu ích khi bạn muốn tách một chuỗi chính thành nhiều chuỗi con dựa trên các mẫu cụ thể. Điều này giống như

Some text
Some more text

748 trên steroid

Chức năng này chấp nhận bốn tham số. Hai cái đầu tiên được yêu cầu trong mọi lệnh gọi của hàm và chúng chỉ định mẫu mà chúng ta nên tìm kiếm và chuỗi chính. Hai tham số tiếp theo là tùy chọn và chúng chỉ định số lượng chuỗi sẽ được trả về và giá trị được trả về có nên được sửa đổi bằng cờ hay không

Đây là một ví dụ chỉ cho bạn cách lấy các tên riêng lẻ từ một chuỗi chứa một danh sách lớn các tên. Các tên được phân tách bằng một hoặc nhiều dấu cách, một hoặc nhiều dấu phẩy hoặc một hoặc nhiều ký tự

Suy nghĩ cuối cùng

Trong hướng dẫn này, chúng ta đã học cách sử dụng một số hàm phổ biến và hữu ích liên quan đến biểu thức chính quy trong PHP. Chúng tôi bắt đầu bằng cách học cách sử dụng

713 hoặc

735 để thay thế các mẫu phù hợp bằng một số chuỗi khác

Biểu thức chính quy cung cấp cho chúng ta một công cụ rất mạnh và dễ vỡ để thao tác chuỗi trong PHP. Bạn phải cẩn thận khi xác định các mẫu của mình, nhưng chúng sẽ tiết kiệm rất nhiều thời gian nếu được sử dụng đúng cách.
