Demonstrates how to set the X-Priority header field of an email.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// The AddHeaderField can be called to add any header field.
// If the header field already exists, AddHeaderField replaces it.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Email')
$email = new COM("Chilkat.Email");
$email->AddHeaderField('X-Priority','3 (Normal)');

$email->AddHeaderField('X-Priority','1 (High)');

$email->AddHeaderField('X-Priority','5 (Low)');

// The X-Priority value ranges from 1 to 5, with 1 being 
// high priority, 3 is normal, and 5 is low.
// You may set X-Priority to the number alone:

$email->AddHeaderField('X-Priority','1');

// Including extra text, such as (High), should not 
// affect how the header is interpreted.
$email->AddHeaderField('X-Priority','1 (High)');
