hai all,

i am trying to get emails from external file.

i get file contants in a string called $contants.

i am using preg_match_all('/^[^0-9][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[@][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[.][a-zA-Z]{2,4}$/',$contents, $matches);

but i am not getting emails.

We would be happy to provide an actual pattern regex, but to do this, we need the actual pattern to be searched for, e.g. the layout of the data in the file -- not all "external files" have the same internal formatting.

There must be more to the internal formatting than this, unless by "i wANT ONLY EMAILS TO EXTRACT" you mean you only want e-mail addresses, not complete e-mails.

There are many examples of e-mail address filters posted on the internet:
