使JavaScript正则表达式等效于PHP正则表达式

$email = 'example@example.com';
if (preg_match('/^\S+@\S+\.\S+$/', $email)) {
    echo 'Valid email address';
} else {
    echo 'Invalid email address';
}

const email = 'example@example.com';
const regex = /^\S+@\S+\.\S+$/;
if (regex.test(email)) {
    console.log('Valid email address');
} else {
    console.log('Invalid email address');
}

$text = 'Visit https://www.example.com';
preg_match_all('/https?:\/\/[^\s]+/', $text, $matches);
print_r($matches);

const text = 'Visit https://www.example.com';
const regex = /https?:\/\/[^\s]+/g;
const matches = text.match(regex);
console.log(matches);

$text = 'Hello, world!';
$text = preg_replace('/world/', 'JavaScript', $text);
echo $text;

const text = 'Hello, world!';
const regex = /world/g;
const newText = text.replace(regex, 'JavaScript');
console.log(newText);
