I am parsing out some emails. Mobile Mail, iPhone and I assume iPod touch append a signature as a separate boundary, making it simple to remove. Not all mail clients do, and just use ‘–‘ as a signature delimiter.
I need to chop off the ‘–‘ from a string, but only the last occurrence of it.
hello, this is some email copy-- check this out -- Tom Foolery
I thought about splitting on ‘–‘, removing the last part, and I would have it, but
split() neither seem to return great values for letting me know if it did anything, in the event there is not a match.
I can not get
preg_replace() to go across more than one line. I have standardized all line endings to
What is the best suggestion to end up with
hello, this is some email copy-- check this out, taking not, there will be cases where there is no signature, and there are of course going to be cases where I can not cover all the cases.
I think in the interest of being more bulletproof, I will take the non regex route
echo substr($body, 0, strrpos($body, "n--"));
