You have a PHP script and you need to validate an email address. How would you do this using Regular Expressions in PHP?
- Use the preg_match() function with a Regular Expression pattern for email validation.
- Use the strtoupper() function to convert the email address to uppercase.
- Use the substr() function to extract a part of the email address.
- Use the is_numeric() function to check if the email address is a number.
To validate an email address using Regular Expressions in PHP, you can use the preg_match() function along with a Regular Expression pattern specifically designed for email validation. By passing the email address as the string to be checked and the appropriate Regular Expression pattern for email validation as the first argument, you can determine whether the email address matches the pattern or not. This allows you to perform a basic validation of email addresses and ensure they conform to the expected format. Learn more: https://www.php.net/manual/en/function.preg-match.php
