WireHttp::getResponseHeaderValues() method

Get last HTTP response headers with multi-value headers as arrays

Use this method when you want to retrieve headers that can potentially contain multiple-values. Note that any code that iterates these values should be able to handle them being either a string or an array.

This method always returns an associative array of strings and arrays, unless you specify the $key option in which case it can return an array, string, or NULL if the header is not present.


// basic usage
$array = $http->getResponseHeaderValues();

// usage with all arguments
$array = $http->getResponseHeaderValues(string $key = '', bool $forceArrays = false);


key (optional)string

Optional header name you want to get (if you only need a specific header)

forceArrays (optional)bool

If even single-value headers should be arrays, specify true (default=false).

Return value

array string null
