DownloadPHP_JSONP_Response
Encode and generate a response to JSONP request
This class can encode and generate a response to JSONP request.
It generates JavaScript code to return JSON encoded variable value as response to a JSONP request.
The generated JavaScript may either invoke a callback function with a name defined by a request variable, or assign a JavaScript variable with the JSON encoded variable value.
Example
PHP
require 'JSONP.class.php';
// Print output with correct headers informations
JSONP::output(array('foo' => 'bar'));
jQuery call
$.ajax({
// Call to url
url: '/path/to/example.php',
// Data Type
dataType: 'jsonp',
// Send data
data: {
foo: 'bar',
baz: 'qux'
},
// On success call
success: function(data) {
// Do stuff with data object
if (data.foo == 'bar') {
alert('Baz!');
}
}
});
Other PHP examples
require 'JSONP.class.php';
// JSON encode data
$json_encoded = JSONP::encode(array('foo', 'bar'));
// JSONP string as returned value
$jsonp_encoded = JSONP::output(array('foo', 'bar'), FALSE);
// Print output
JSONP::output(array('foo', 'bar'));
// Print output without headers
JSONP::output(array('foo', 'bar'), TRUE, FALSE);
