How can PHP be used to extract text from HTML emails efficiently?

To extract text from HTML emails efficiently using PHP, you can use the strip_tags() function to remove all HTML tags and only keep the text content. This allows you to easily extract and process the text without any HTML markup.

// Sample HTML email content
$htmlContent = "<html><body><h1>Hello World!</h1><p>This is a sample email.</p></body></html>";

// Extract text from HTML email
$textContent = strip_tags($htmlContent);

// Output the extracted text
echo $textContent;
