Re: [PHP] Name of variable to string
tedd wrote: Hi gang: From a variable with the name of $this_variable -- how do I get a string 'this_variable' ? Cheers, tedd At some point or the other you will have to define $this_variable as $this_variable, so at that point you will have access to the string 'this_variable'. Even if you define it using variable vairables or within or for each loop (e.g. get_definied_vars, $_POST) you will have an oppertunity to get the 'this_variable' string.

Somthing like this works ok, you can further refine it for the purpse
you want.

Re: [PHP] PHP LDAP - Single Sign On
thanks for the response, i can see how this works (i think) for basic authentication with user input,but what i really need is to actually retrieve the logged on user name after a user has logged into windows. i.e. the user name that the http client passes to the apache mod has been captured not from user input, but from say a piece of code that picks up the user name when the user logs in. Probably less to do with php now that i come to think of it, but thanks anyway.

[PHP] displaying documents stored under web root
Hi After some advice (surprise!) I currently store restricted documents beneath the web root so they are not accessible via the URL, when a valid user wishes to view a document i copy it to a temporary folder above the root and load it in a new page. the only way i can then manage to delete the copy is automatically deleting all temp files when any user goes to the log out page. This is obviously not a very good way of doing this but unless i can establish when a user is no longer viewing the doc then i dont know when to delete it.

Definitely sounds as if you should be employing the object-orientated methodology, If the project is as big as you say it is then really you should be looking to use some UML planning tool so that you can keep all you code organised.

[PHP] Automatic log out
Hi I currently use an automatic logout out system that sets a time out in two ways. (If the ip address on computer is recognized then set timeout to 10 mins, if not then set to 2 mins.) 1) The time out setting is used to create a meta refresh tag that will re-direct the user to the logout page after X seconds. 2) At the beginning of each page i set a variable with the current time and check to see if the difference between the previously set variable and the now current time is greater than X seconds, if so then log the user out. I know meta refresh is not to be relied on and that is why i use the 2nd method as well, but i have had varied reports that this system does not work, i.e. it logs people out to quickly. Does anyone know a better way of doing this or improvements?? it would also be nice to stop the pages displaying after a time out when a user presses the back button!

Re: [PHP] create HTML page on the fly
I think you can use a different handle when using fwrite() which will
make php create a file if one is not already there: something like
if ($fp = fopen($file,x+)){
echoopened;
}
fwrite($fp,$content);
fclose($fp);

Hi guys.
I've created a small newsletter application and the content of the
newsletter is stored in a DB (the HTML).
However once the newsletter is complete and the user clicks a button I
want the newsletter/html file to be created on the server. How do I
go about this?
I assume that I will use fwrite() to add the HTML to the file, I need
to know how to actually create the file before adding the content to it.
thanks in advance.
