How to get variable value in mail header php
In PHP, you can access the value of a variable in the mail header using the headers
function and the mail
function. Here are a few ways to do it:
Method 1: Using the headers
function
$headers = array(
'From: '. $from_email,
'To: '. $to_email,
'Subject: '. $subject,
'X-Variable: '. $variable_value
);
mail($to_email, $subject, $message, implode("\r\n", $headers));
In this example, $variable_value
is the value of the variable you want to include in the mail header.
Method 2: Using the mail
function with the extra_headers
parameter
mail($to_email, $subject, $message, null, 'X-Variable: '. $variable_value);
In this example, the extra_headers
parameter is used to specify the additional headers, including the value of the variable.
Method 3: Using a custom mail function
function send_email($to_email, $subject, $message, $headers) {
$headers = array_merge(array(
'From: '. $from_email,
'To: '. $to_email,
'Subject: '. $subject
), $headers);
mail($to_email, $subject, $message, implode("\r\n", $headers));
}
$headers = array('X-Variable: '. $variable_value);
send_email($to_email, $subject, $message, $headers);
In this example, a custom send_email
function is defined that takes an array of headers as a parameter. The array_merge
function is used to combine the default headers with the custom headers, including the value of the variable.
In all cases, make sure to replace $from_email
, $to_email
, $subject
, $message
, and $variable_value
with the actual values you want to use.
