Re: Try to find a solution, when restart Apache with PHP Script

Daevid, understood... but in my case the php script is called once one time, and then keep's on running "forever" on a server background shell... The user never will have to worry about the process again, but if the process is not running on the server a message will apear on the interface or a email will be send to the administrator (me and others)... The best solution for me will be the possibility of running this PHP script on other port than the default using by apache. Thanks Daevid Vincent escreveu:

We put a timeout at the top and show an error if the server never comes back. You could do whatever you want. As long as the user doesn't try to refresh the page or go somewhere else on your server, the ajax will just keep trying in the background. That's all client-side JS / AJAX.

To: php-general@lists.php.net Subject: [PHP] 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... ---------------------------8< snip
