function MessageInterface::getHeaders
Retrieves all message header values.
The keys represent the header name as it will be sent over the wire, and each value is an array of strings associated with the header.
// Represent the headers as a string foreach ($message->getHeaders() as $name => $values) { echo $name . ": " . implode(", ", $values); }
// Emit headers iteratively: foreach ($message->getHeaders() as $name => $values) { foreach ($values as $value) { header(sprintf('%s: %s', $name, $value), false); } }
While header names are not case-sensitive, getHeaders() will preserve the exact case in which headers were originally specified.
Return value
string[][] Returns an associative array of the message's headers. Each key MUST be a header name, and each value MUST be an array of strings for that header.
