使用 preg_match 从一个完整的句子中提取一些信息

Question

我想在 php 中使用 preg_match 提取特定信息。有什么想法吗？

sample text = 2xMUA Matte Lipstick - Totally Nude[300]=[600]

这里我要

product_name = MUA Matte Lipstick - Totally Nude
product_qty = 2
product_price = 300
product_subtotal = 600

Answer 1

您可以在（命名）captured groups.

中捕捉您的价值观

这样试试：

(?<qty>\d+)x(?<name>[^[]+)\[(?<price>[^]]+)\]=\[(?<subtotal>[^]]+)\]

那将匹配：

(?<qty>      # Named captured group qty
  \d+        # One or more digits
)            # Close group
x            # Match x
(?<name>     # Named captured group name
  [^[]+      # Match not [ one or more times
)            # Close group
\[           # Match [
(?<price>    # Named captured group price
  [^]]+      # Match not ] one or more times
)            # Close group
\]=\[        # Match ]=[
(?<subtotal> # Named captured group subtotal
  [^]]+      # # Match not ] one or more times
)            # Close group
\]           # Match ]

Demo php

或没有命名的捕获组：

(\d+)x([^[]+)\[([^]]+)\]=\[([^]]+)\]
