PHP Code Example

<?php
// Generate Random Email with Random Username
function randomEmail($domain = 'example.com') {
    $username = bin2hex(random_bytes(8));
    return $username . '@' . $domain;
}

echo "Random Email: " . randomEmail() . "\n";
echo "Custom Domain: " . randomEmail('test.org') . "\n";

// Generate Email with Readable Username
function readableEmail($domain = 'example.com') {
    $adjectives = ['happy', 'sunny', 'clever', 'bright', 'quick'];
    $nouns = ['panda', 'tiger', 'eagle', 'dolphin', 'falcon'];

    $username = $adjectives[array_rand($adjectives)] .
                $nouns[array_rand($nouns)] .
                rand(100, 999);

    return $username . '@' . $domain;
}

echo "Readable Email: " . readableEmail() . "\n";

// Generate Email from Name Pattern
function emailFromName($firstName, $lastName, $domain = 'company.com') {
    $patterns = [
        strtolower($firstName . '.' . $lastName),
        strtolower($firstName[0] . $lastName),
        strtolower($firstName . $lastName[0]),
        strtolower($firstName . '_' . $lastName),
    ];

    $username = $patterns[array_rand($patterns)];
    return $username . '@' . $domain;
}

echo "Name-based: " . emailFromName('John', 'Doe') . "\n";

// Generate Test Email with Timestamp
function testEmail($domain = 'test.local') {
    $username = 'test_' . time() . '_' . rand(1000, 9999);
    return $username . '@' . $domain;
}

echo "Test Email: " . testEmail() . "\n";

// Generate Multiple Unique Emails
function generateEmails($count, $domain = 'example.com') {
    $emails = [];
    for ($i = 0; $i < $count; $i++) {
        $emails[] = 'user' . uniqid() . '@' . $domain;
    }
    return $emails;
}

print_r(generateEmails(3));

// Validate Email Format
function isValidEmail($email) {
    return filter_var($email, FILTER_VALIDATE_EMAIL) !== false;
}

$email = randomEmail();
echo "Valid: " . ($isValidEmail($email) ? 'Yes' : 'No');

[EXPLANATION]

PHP generates random emails by combining random usernames with domain names. Use bin2hex(random_bytes()) for completely random usernames, or combine word arrays for readable emails. uniqid() generates unique identifiers based on current time. For name-based emails, convert names to lowercase and use common patterns (firstname.lastname, firstinitiallastname). Always use test domains like example.com, test.local, or .test TLD to avoid sending to real addresses. filter_var() with FILTER_VALIDATE_EMAIL validates email format according to RFC 5322.

Expected Output

Random Email: a3f5d8c2e1b4f7a9@example.com
Custom Domain: 7b3e9c1f5a2d8e4b@test.org
Readable Email: cleverdolphin847@example.com
Name-based: john.doe@company.com
Test Email: test_1703001234_7382@test.local
Array
(
    [0] => user6574a2f1b3c8e@example.com
    [1] => user6574a2f1b3d12@example.com
    [2] => user6574a2f1b3d3a@example.com
)
Valid: Yes
