В этой записи не будет всякого рода «разжовывания» по регулярным выражениям, тут примеры и описание и все.
Проверка e-mail адреса
[sourcecode language='php']
$email = firs...@aaa.bbb.com;
$regexp = "/^[^0-9][A-z0-9_]+([.][A-z0-9_]+)*[@][A-z0-9_]+([.][A-z0-9_]+)*[.][A-z]{2,4}$/";
if (preg_match($regexp, $email)) {
echo "Email address is valid.";
} else {
echo "Email address is not valid.»;
}
?>
[/sourcecode]
Многоточие
[sourcecode language='php']$text = preg_replace(‘/\.{3}/’, ‘…’, $text);[/sourcecode]
