Zend_Amf provides tools for mapping resource types
returned by service classes into data consumable by ActionScript.
In order to handle specific resource type, the user needs to create a plugin class named
after the resource name, with words capitalized and spaces removed (so, resource
type "mysql result" becomes MysqlResult), with some prefix, e.g.
My_MysqlResult. This class should implement one method,
parse(), receiving one argument - the resource - and returning
the value that should be sent to ActionScript. The class should be located in the file
named after the last component of the name, e.g. MysqlResult.php.
The directory containing the resource handling plugins should be registered with
Zend_Amf type loader:
<?php
Zend_Amf_Parse_TypeLoader::addResourceDirectory(
"My",
"application/library/resources/My"
);
For detailed discussion of loading plugins, please see the plugin loader section.
Default directory for Zend_Amf resources is registered
automatically and currently contains handlers for "mysql result" and "stream"
resources.
<?php
// Example class implementing handling resources of type mysql result
class Zend_Amf_Parse_Resource_MysqlResult
{
/**
* Parse resource into array
*
* @param resource $resource
* @return array
*/
public function parse($resource) {
$result = array();
while($row = mysql_fetch_assoc($resource)) {
$result[] = $row;
}
return $result;
}
}
Trying to return unknown resource type (i.e., one for which no handler plugin exists) will result in an exception.
