How PHP handles Java-coming interfaces and the JSON string that PHP returns to JavaScript

If you want to handle Java interface. This is how it behaves in PHP:

<?php  
    $url = ' The interface URL address for Java provided here ';//We are unified using JSON format  
    $ch = Curl_init ();  
    $timeout = 5;  
    curl_setopt ($ch, Curlopt_url, $url);  
    curl_setopt ($ch, Curlopt_returntransfer, 1);  
    curl_setopt ($ch, Curlopt_post, 1);  
    curl_setopt ($ch, Curlopt_connecttimeout, $timeout);  
    $contents = curl_exec ($ch);  
    Curl_close ($ch);  
    $body = Json_decode ($contents, TRUE);  
    $data = Array ();  
    if ($body [' code '] = = =  
        $data = (array) $body [' Data '];

The following is a JSON string that has been processed to return to JavaScript. You just need to put the address of the controller in the form of a URL to the docking personnel can be.

<?php Public  
function Action_actionname ()  
{  
    header (' Content-type:application/x-javascript ');  
    For example, the request  
    header (' access-control-allow-origin:.baidu.com ') that receives only the. baidu.com domain name;  
    $callback = Isset ($_get[' callback '))? $_get[' callback ']: ' Callback ';  
    try {  
        $rows = select * from *******;//Here is a SELECT statement that extracts results from the database  
        $data = array (  
            ' code ' =>,  
            ' msg ' 
  
   => ' success ',  
            ' data ' => $rows,  
        );  
    } catch (Exception $e) {  
        $data = array (  
            ' code '  => 3000004,  
            ' msg '   => ' illegal operation ',  
        );  
    }  
    echo $callback. ' ('. Json_encode ($data). ') ';  
    Exit;  
}
