Question

Im using php with mssql function (Xampp). Im trying to do a so-called progress bar for my user to see the process running behind. So, from a form, i send it to two php pages. one is the processing page and another one is the progress bar (popup window) page.

The processing page work fine, insert, update the database. but the problem is another page, which is the progress bar page keep on hang after refresh.

If i run both page using different browser (firefox and chrome), the progress bar working fine, but if both running in the same browser (eg: im using firefox4), the progress bar script will halt and error of ‘Maximum execution time of 60 seconds exceeded’ appear

fyi, both page use the same database and same table..

many2 thanks in advance….

Answer 1

PHP sessions are known to block other pages accessing the same session concurrently.

Have a look at session_write_close

but as session data is locked to
prevent concurrent writes only one
script may operate on a session at any
time.

This would explain why accessing the progress bar using a different browser works.
