WpOrg\Requests\Response

Headers::offsetGet() │ public │ WP 1.0

Get the given header

Unlike \WpOrg\Requests\Response\Headers::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.

Method of the class: Headers{}

No Hooks.

Return

String|null. Header value

Usage

$Headers = new Headers();
$Headers->offsetGet( $offset );
$offset(string) (required)
Name of the header to retrieve.
