1. Judge Email:

Domain names are composed of specific character sets, English letters, numbers, and "-" (that is, hyphens or minus signs) of each country's text, but neither the beginning nor the end can contain "-", "-" and "-" cannot appear continuously. The letters in the domain name are not case-insensitive. The domain name can be up to 60 bytes (including suffix. com,. NET,. org, and so on).
/^[a-z] ([a-z0-9]*[-_]?[ a-z0-9]+) *@ ([a-z0-9]*[-_]?[ a-z0-9]+) +[.] [A-z] {2,3} ([.] [A-z] {2})? $/i;
/content/I forms a case-insensitive regular expression;

The basic rules are as follows

The code is as follows Copy Code
Preg_match ('/^[a-z0-9_-]+. [ _a-z0-9-]+) *@ ([_a-z0-9-]+.) + ([a-z]{2}
|aero|arpa|biz|com|coop|edu|gov|info|int|jobs|mil|museum|name|nato|net|org|pro|travel) $/', $email)

Example 1

The code is as follows Copy Code

<?php
function Is_email ($email) {
return strlen ($email) > 6 && preg_match ("/^[w-.] +@[w-]+ (. w+) +$/", $email);
}
?>

Example 2

The code is as follows Copy Code

<body>
<?php
$email _pattern = '/w{6,16}@w{1,}.w{2,3}/i ';
$email _valid = ' test_123@126.net ';
$email _invalid = ' test@test%@111@com ';
$matches = Array ();

Preg_match ($email _pattern, $email _valid, $matches []);
Preg_match ($email _pattern, $email _invalid, $matches []);

Var_dump ($matches);
