I don't understand the issue either. The code behaves the same way for me
regardless of the line ending in test.txt.
Can you provide a simpler example, please?

I don't really understand the issue you have from your example, but in general
LF is the compile-default linebreak for PCRE. If you want to use a different
linebreak character you can either compile PCRE with the appropriate option or
specify a control option like (*CRLF) before your regular expression.

Ok. here is my guess at what is confusing you.
By default PCRE uses \n to indicate the end of a line. Your files have \r\n at
the end, so I think the only confusion you have is that your second match will
have \r included in it and when you then print this on the console it looks
essentially invisible.
In your latest example there, try changing your output line to this:
echo $matches[1].trim($matches[2]);
Does it make more sense now?
