In the stack-overflow question here , it was explained that you can remove emails with this code:
$pattern = "/[^@\s]*@[^@\s]*\.[^@\s]*/";
$replacement = "[removed]";
preg_replace($pattern, $replacement, $string);
This removes stuff like johndoe@gmail.com - how do I modify the regular expression so that I remove something like @johnDoe from a chunk of text?
I really don't understand regular expression that well.
use
$pattern = "/@[^@\s]*/";
In [^@\s]:
\s stands for any space character[@\s] stands for a character group, containing \s (i.e. space) and the @ character. it matches either @ or \s[^@\s] stands for the character group that is not @\s[^@\s] matches a single character that is not @ character or \s (i.e. spaces)* after it stands for the previous token (i.e. [^@\s] here) can repeat zero or more times. Hence, [^@\s]* matches string of any length as long as it does not contain @ or \s
As a side note, your link give a much-simplified regex for matching e-mails. The perfect way of matching e-mails are no simple matter.
