This should be simple, but i haven't done it before...
KSH
I am reading a file into an array and currently displaying the values to the screen. What I need to do is to display a subset of those values, likely numbered, and prompt the user to select one. When they enter the number, it retrieves the assoicated array value and outputs it to the screen. (this will be used for more complex functions later)
For example, the program is run and the first 10 rows are displayed. I select a number or hit a character to proceed to the next page. This would dump the first 10 rows and load the next 10 (into another array?) I select a value and the row associated with that value echoes to the screen.
Any suggestions are greatly appreciated.
My code so far:

I have an interactive menu script written in bash and I would like use PHP to open the interactive bash menu in a browser.
Is this possible?
Using the sytem() function in php runs the script but it's all garbled.
Seems like maybe a terminal window needs to be opened in php first?

scandir
SCANDIR(3) Library Functions Manual SCANDIR(3)NAME
scandir, alphasort - scan a directory
SYNOPSIS
#include <sys/types.h>
#include <sys/dir.h>
scandir(dirname, namelist, select, compar)
char *dirname;
struct direct *(*namelist[]);
int (*select)();
int (*compar)();
alphasort(d1, d2)
struct direct **d1, **d2;
DESCRIPTION
Scandir reads the directory dirname and builds an array of pointers to directory entries using malloc(3). It returns the number of entries
in the array and a pointer to the array through namelist.
The select parameter is a pointer to a user supplied subroutine which is called by scandir to select which entries are to be included in
the array. The select routine is passed a pointer to a directory entry and should return a non-zero value if the directory entry is to be
included in the array. If select is null, then all the directory entries will be included.
The compar parameter is a pointer to a user supplied subroutine which is passed to qsort(3) to sort the completed array. If this pointer is
null, the array is not sorted. Alphasort is a routine which can be used for the compar parameter to sort the array alphabetically.
The memory allocated for the array can be deallocated with free (see malloc(3)) by freeing each pointer in the array and the array itself.
SEE ALSO directory(3), malloc(3), qsort(3), dir(5)DIAGNOSTICS
Returns -1 if the directory cannot be opened for reading or if malloc(3) cannot allocate enough memory to hold all the data structures.
