concurrent/very fast php session requests pile up when using php sessions -

i using php sessions , utilize session variable prevent requests hitting same script until first 1 time finishes. need on per user basis.

is alternative create database table tracks if possible run query? seems sessions wait (unless session_write_close() called). session_write_close won't work in case.

i want this:

here basic logic

if (!$this->session->userdata('sales_report_running')) { $this->session->set_userdata('sales_report_running', true); //do expensive query $this->session->set_userdata('sales_report_running', false); }

php session
