I want to repeatedly ping a computer and log when I no longer can ping them. So I need to record the last time it was able to ping the computer.

I have a function and I am defining an array inside it. However I declare the array outside the function so I thought it would be global, however outside the function I can't read the array. I define it as: $imagearray = array(); Then I define each component inside the function.

I am passing a varialbe to opendir, I want to send the directory through the url. My server does not seem to process the variable as a string or something though. When I type in the name of the directory it reads it. What is going on? The code that doesn't work is: $dir = "./".$gallery."/"; if...

I am trying to pass a variable directory name to a script but it seems to just open the root directory on the server. Why won't this work: opendir('/'.$gallery.'/') But this does when I specify the string in the code: opendir('/directory/'); Is the variable somehow not a string or something? I...

What is the best way to extract a random file name from its whole path when the file name and path will always be unique? EX: C:\Documents and Settings\My Documents\Zinni\MTmFreq140dB63_072204.txt I want the .txt file name. Is there a way to search a string backwards for the '\'?

What is an easy way to get rid of a leading space on a randomly size string?

I need to select a radio button when I click on an input field. Is there a set focus command to select a radio button?

I have a string: 3.333332976326346e-004 When I use atof is returns 0.00. Is this string too long? Whats going on?

Does anybody know of another way to fix this?

Actually I figured out that the carriage return before each rget is the return sent from the previous command. So to fix it, even thought its a pain, I can put the rxflush command in before each rget.

I added set aspect rgetchar 13 STRIP and it strips the carriage return following the returned string. But I still have a carriage return before the string. How can I eliminate this?

I typed: set duplex full in my script but when I go to Options it shows half duplex. What is going on?

I need to compare two sets of strings but I am finding it hard with this primitive language. I need to do this: if ((string1 != string2) && (string1 != string3)) the strcmp does not want to work well with ! or 'not'

I am encountering problems retrieving responses from a unit over the serial port because rget seems to want to grap the transmitting commands. I tried changing the duplex and thought it worked at first, but aparently not. I have to transmit a command, then my system responds and I want to read...

I want to know how much cpu time it takes the server to read files off the a directory. Basically I want to know if it takes a lot of server time to load all the file names using readdir() because I run it every time this page loads, which is meant to be a lot.

How do I pass an array over? I believe the array is global because I declared it outside any functions.

This is what I do: I read file names in a directory and store them in an array, then I want to pass that array over to the next page like the same way you submit variables from a form to another page.

I need to pass an array to the same page as it refreshes, I don't want to have to load the array every time the page loads. Is there a way to do this?

Is there a command that can snag data out of the buffer and display it at the same time? The rget steals the text away preventing it from being printed.

I found an interesting thing happen and this is why I thought the waitfor commands were not working! I was using waitfor for the same thing I was transmitting, and for some reason the waitfor read the sent command and reported it got the data. I found this out by specifying MATCHCASE for the...
