Question

I have declared a structure that look like

 typedef struct
 {
     char* key;
     char* value;
 }kvPair;

and in the session structure, i declared a variable as

 struct session
 {

    char* id;
    .....  // other session variables
    kvPair* pair;
  }

Now in the session_start I have initialised the values for the pair variable and I have to access these values in /ext/mysql extension. A suggestion on how to achieve it would be greatly appreciated

I’m not sure what you’re trying to do, but if you want to read data that was saved in the session e.g. through this script:

<?php
session_start();
$_SESSION["key"] = "data";

Then yes, you can use the API exposed by the session extension:

#include "ext/session/php_session.h"

Then you have these functions:

void php_session_start(TSRMLS_D); /* analogue to session_start() in userspace */
int php_get_session_var(char *name, size_t namelen, zval ***state_var TSRMLS_DC);
