[PHP] Strip emails from a document
Hi gang: I thought I had a function to strip emails from a document, but I can't find it. So, before I start writing a common script, do any of you have a simple script to do this? Here's an example of the problem: Before: Will Alex ale...@cit.msu.edu;Moita Zact za...@cit.msu.edu;Bob Arms ar...@cit.msu.edu;Meia Terms term...@cit.msu.edu; After: ale...@cit.msu.edu za...@cit.msu.edu ar...@cit.msu.edu term...@cit.msu.edu Cheers, tedd _ t...@sperling.com http://sperling.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Strip emails from a document
I think you meant extract emails from document, right? I'd probably find `@` and iterate before and after unless I get posix punct, space, characters. But it'll probably give some false matches. So its really hard to find 100% emails from an arbitrary text. This is because valid email can contain many different type of characters. According to RFC 822 space is a valid character in email. So finding all the valid emails is tough. In a *trivial situation* an email would be separated by space. So find @ first. Then go back and front to find the first space. You'll get most common emails. Something like using this regex pattern [^[:space:]@]+@[^[:space:]]+ would suffice. But keep in mind, it'll work on trivial cases. Not on special cases. Regular expression can not be used on special cases.

Re: [PHP] Strip emails from a document
If you are expecting the email address to always be the same but the first part being different you can create a regular expression to match it that way. Using a regular expression over all is going to be your best bet as shiplu suggested.

It's imperfect, but will work for the majority of emails:

It works imperfectly enough for me. :-)

I have a function that will take a comma separated string consisting of emails in these formats: Soap, Joe joe.s...@example.com Joe Soap joe.s...@example.com (Joe Soap) joe.s...@example.com and turn them into a list where all the above examples are converted to: Joe Soap joe.s...@example.com but it won't handle things like: joe@soap@example.com which I understand is also valid.
