Subject: Try to find a solution, when restart Apache
with PHP Script
Hi all...
I'm facing a serious problem with my application. I have a
script write
in PHP that starts in Internet Explorer, this script keep on running
until a varible value change on my MySQL database.
The problem is that when i restart Apache, the process child
initalized
isn't kill... then the apache can't be start because the script is use
the port 80.
To solve my problem, without change anything, the best would be that
when i execute the script, it run on other port than the default 80...
so this way apache could start...
The is a way to redirect through php, so the script run on a diferent
port?? Like change some line, or add on php.ini files?? or even in
programming??
thanks ... for any info
We do something like this, wherein sometimes we have to force a restart of
Apache, so in order to not kill the web page for the GUI, we use AJAX to
continually poll the server. Then when the server is back, we can issue a
page refresh to whatever page we want...
