I was studying the PCRE manual. I am confused with the definition and its practice usage of following pattern modifiers
\A - Anchored
\m - multiline
\D - dollar_only
\J - info_jchanged
\S
I am mostly clear about the use of \m that it starts to read the newline character, without it whole string including newline characters are considered as a single character but i am confused about this line from the manual
"The "start of line" metacharacter (^) matches only at the start of the string, while the "end of line" metacharacter ($) matches only at the end of the string, or before a terminating newline (unless D modifier is set)"
Also are \D and \m equivalent or different in behavior? I failed to find any practical examples of these modifiers and would really appreciate if anybody could help me understand their usage.
Thank you very much!
