Are there any best practices for handling variables with special characters, such as "=" in PHP when generating dynamic content for emails?

When handling variables with special characters like "=", it's important to properly encode them to prevent any syntax errors or unintended behavior in the generated content. One way to do this is by using the urlencode() function in PHP to encode the special characters before including them in the email content. 

// Example of encoding a variable with special characters before using it in an email
$special_var = "special=character";
$encoded_var = urlencode($special_var);

// Include the encoded variable in the email content
$email_content = "Special variable: " . $encoded_var;

// Send the email with the encoded variable
// (code for sending email not included in this example)
