Requests_Response_Headers::offsetGet( string $key )

Get the given header

Description

Unlike self::getValues(), this returns a string. If there are multiple values, it concatenates them with a comma as per RFC2616.

Avoid using this where commas may be used unquoted in values, such as Set-Cookie headers.

Parameters

$key

(string) (Required)

Return

(string|null) Header value
