Question

In a string I have somthing like this:

[select|blog]
    Some text some text some text
[/select]

more text more text more text

[select|information]
    Some text some text some text
[/select]

Now using preg_match I would like the function to:

• get the text between the [select] tags
• change it
• insert it back into the string
• remove the select tags

So in the end it will become something like this:

Changed text1 Changed text1 Changed text1

more text more text more text

Changed text2 Changed text2 Changed text2

Hope you guys can help me out. Thanks! 🙂

Answer 1

This regex will get you started

\[.*?](.*?)\[.*?]

Put the option on that allows the dot . to match new line

The text inside the brackets is in group 1

I’m coming from the .NET world so I would tackle this with a function that I can let get executed after each match.
The input of this function is the match. Here you can get to group 1 if you need to access to it and rewrite or put your new content.

I just read in the comments that the equivalent in php is preg_replace_callback()
