Question

In Zend Framework in Response Class there are two different arrays for storing headers: _headers[] and _headersRaw[]. And there are appropriate methods for setting each one:

setHeader(), getHeaders(), clearHeader() and

setRawHeader(), getRawHeaders(), clearRawHeaders().

What is the reason to have “header” and “raw header”? Is there some special kind of usage in practice for each of these headers?

Answer 1

using setHeader you set key vale pair without worrying about there formatting e.g

$this->getResponse()->setHeader('Content-type','json');

while in case of setRawHeader() you put the whole/full header as it is with proper formating
