Installation

composer require arraypress/email-validator

Usage

Validation

if ( is_valid_email( 'user@example.com' ) ) {
    // Valid email
}

Sanitization

$clean = sanitize_email( '  USER@EXAMPLE.COM  ' );
// Returns: 'user@example.com'

$clean = sanitize_email( 'test@domain..com' );
// Returns: 'test@domain.com'

$clean = sanitize_email( 'invalid' );
// Returns: '' (empty string)

Validation Rules

  • Length: 6-254 characters
  • Single @ symbol after first position
  • No whitespace or control characters
  • Local part: max 64 characters, valid characters only, no leading/trailing/consecutive dots
  • Domain: at least two parts, no consecutive dots, no leading/trailing hyphens
  • TLD: minimum 2 characters, alphabetic only

Sanitization Behavior

  • Trims whitespace
  • Converts to lowercase
  • Strips invalid characters from local part
  • Normalizes consecutive dots in domain
  • Removes leading/trailing dots and hyphens from domain parts
  • Returns empty string if email cannot be sanitized to valid format

Requirements

  • PHP 8.0+
