I am writing this simple program but I am stuck at this point. Here is the snippet from my script where I have issues.
This is a section of the script where it takes entry either 3 or 4. If 3 is selected it prompts for the user to enter filename and if the user is hitting just enter and not any filename, it should return to main menu. But that's not happening, its just looping around and waiting for an input. But if 4 is selected and an enter is pressed with out directory name it goes to that cd $dname part and moves to main menu. Since $dname is empty as the user has not provided any value it goes to home directory of the user.
My requirement is that the script should go back to main menu if the user hits just "enter" with out any value. How can I achieve that?

LEARN ABOUT PHP
dir
DIR(3) 1 DIR(3)dir - Return an instance of the Directory classSYNOPSIS
Directory dir (string $directory, [resource $context])
DESCRIPTION
A pseudo-object oriented mechanism for reading a directory. The given $directory is opened.
PARAMETERS
o $directory
- Directory to open
o $context
-
Note
Context support was added with PHP 5.0.0. For a description of contexts, refer to "Streams".
RETURN VALUES
Returns an instance of Directory, or NULL with wrong parameters, or FALSE in case of another error.
EXAMPLES
Example #1
dir(3) example
Please note the fashion in which Directory.read(3)'s return value is checked in the example below. We are explicitly testing
whether the return value is identical to (equal to and of the same type as - see Comparison Operators for more information) FALSE
since otherwise, any directory entry whose name evaluates to FALSE will stop the loop.
<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "
";
echo "Path: " . $d->path . "
";
while (false !== ($entry = $d->read())) {
echo $entry."
";
}
$d->close();
?>
The above example will output something similar to:
Handle: Resource id #2
Path: /etc/php5
apache
cgi
cli
NOTES
Note
The order in which directory entries are returned by the read method is system-dependent.
