PHP-MYSQL存储过程输出参数

Question

I have a mysql stored procedure that takes 3 parameters - 2 In and 1 out I am calling this procedure from php using mysqli

The procedure will return 1 row and I use the following code when calling it

    $result = $mysqli->query("call get_hybrid_auth_session('".$userId."','".$loginSystem."', @hybridAuthSession)");
    $result = $mysqli->query( 'SELECT @hybridAuthSession' );
    $row = $result->fetch_object();

When I do a var_dump on the $row attribute, I get the following text back

object(stdClass)#16 (1) { ["@hybridAuthSession"]=> string(287) ".a:3:{s:40:"hauth_session.twitter.token.access_token";s:56:"s:48:"23801232-fkv05uitVRobpItrFFUn15I4Ejl0w80pr7GOH0A";";s:47:"hauth_session.twitter.token.access_token_secret";s:51:"s:43:"VKsFaQWnP8n9OcZK3MDCgRHQY0roLTFVXesBuONCYJo";";s:34:"hauth_session.twitter.is_logged_in";s:4:"i:1;";}." } 

When I do a var_dump on the $row->{"@hybridAuthSession"} attribute, I get the following value back

string(287) ".a:3:{s:40:"hauth_session.twitter.token.access_token";s:56:"s:48:"23801232-fkv05uitVRobpItrFFUn15I4Ejl0w80pr7GOH0A";";s:47:"hauth_session.twitter.token.access_token_secret";s:51:"s:43:"VKsFaQWnP8n9OcZK3MDCgRHQY0roLTFVXesBuONCYJo";";s:34:"hauth_session.twitter.is_logged_in";s:4:"i:1;";}."

Is there any way to not receive the string(287) value at the start? The hybridAuthSession Out parameter is defined as Text in my stored procedure

Answer 1

Var dump was adding additional information when outputting the text to the screen which is its expected behaviour. After some more tests, the code was working as expected
