What role does the email client play in the proper rendering of HTML emails sent from PHP scripts?

The email client plays a crucial role in the proper rendering of HTML emails sent from PHP scripts because different email clients may interpret HTML code differently. To ensure consistent rendering across various email clients, it is important to use inline CSS styles, include a plain text version of the email, and test the email in multiple clients before sending it out. 

// Example PHP code snippet for sending an HTML email with inline CSS styles

$to = 'recipient@example.com';
$subject = 'HTML Email with Inline CSS';
$message = '<html><head><style>body { color: #333; font-family: Arial, sans-serif; }</style></head><body><h1>Hello, World!</h1><p>This is an example HTML email with inline CSS styles.</p></body></html>';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

mail($to, $subject, $message, $headers);
