The main goal of the response object is to provide easy access to various response parameters.
getStatus(): Get the HTTP response status code (eg. 200, 504, etc.)getMessage(): Get the HTTP response status message (eg. "Not Found", "Authorization Required")getBody(): Get the fully decoded HTTP response bodygetRawBody(): Get the raw, possibly encoded HTTP response body. if the body was decoded using GZIP encoding for example, it will not be decoded.getHeaders(): Get the HTTP response headers as an associative array (eg. 'Content-type' => 'text/html')getHeader($header): Get a specific HTTP response header, specified by $headergetHeadersAsString($status_line, $br): Get the entire set of headers as a string. If$status_lineisTRUE(default), the first status line (eg. "HTTP/1.1 200 OK") will also be returned. Lines are broken with the$brparameter (Can be, for example, "<br />". Default "\n")asString($br): Get the entire response message as a string. Lines are broken with the $br parameter (Can be, for example, "<br />". Default "\n"). You can also use the magic method__toString()when casting the object as a string. It will then proxy toasString().
Example 490. Using Zend_Http_Response Accessor Methods
<?php
if ($response->getStatus() == 200) {
echo "The request returned the following information:<br />";
echo $response->getBody();
} else {
echo "An error occurred while fetching data:<br />";
echo $response->getStatus() . ": " . $response->getMessage();
}
Always check return value
Since a response can contain several instances of the same header, the getHeader() method and getHeaders() method may return either a single string, or an array of strings for each header. You should always check whether the returned value is a string or array.
Example 491. Accessing Response Headers
<?php
$ctype = $response->getHeader('Content-type');
if (is_array($ctype)) $ctype = $ctype[0];
$body = $response->getBody();
if ($ctype == 'text/html' || $ctype == 'text/xml') {
$body = htmlentities($body);
}
echo $body;
