How can PHP developers remove unnecessary text/html parts from email content to display only the desired text?

To remove unnecessary text/html parts from email content in PHP, developers can use regular expressions to extract only the desired text. By using regex patterns to identify and remove unwanted HTML tags or text, developers can clean up the email content before displaying it to the user.

$emailContent = "<html><body><p>This is the <strong>desired text</strong> we want to display.</p></body></html>";

// Remove HTML tags and keep only the desired text
$cleanedContent = strip_tags($emailContent);

echo $cleanedContent;
