Find and Replacing text?

[netfrugal]

I have a ton of emails that I want to change:

For example:

[e-mail] -> [e-mail]
[e-mail] -> [e-mail]
[e-mail] -> [e-mail]
[e-mail] -> [e-mail]

I am sure there is a search and replace function that can replace everything between the '@' sign and the '.com' to 'mydomain'

but I can't find it.

Any help would be appreciated!
thanks!

$repl = 'mydomain.com';
$pos = strpos($addr, '@') + 1;
$addr = substr_replace($addr, $repl, $pos);

$string = "[e-mail]";
echo preg_replace('/^([-a-z0-9_\.]+)@.*/i', '\\[e-mail]', $string);

Or

$string = "[e-mail]";
list($name) = explode('@', $string);
echo "$[e-mail]";

Don't forget:

$repl = '@mydomain.com';
$addr = str_replace(strrchr($addr, '@'), $repl, $addr);

or

$addr = str_replace(strpbrk($addr, '@'), $repl, $addr);

or

$addr = strtok($addr, '@') . $repl;

or

$addr = substr($addr, 0, strcspn($addr, '@')) . $repl;
