How to maintain the content of array in any directory - pliz helppp!
Hi all,
I have this scenario where:-
The file that I want to save its name into array df[1] is my.08120323.trx which is located in the dir as below:
$ pwd
/u01/abc/def/SRC_datafiles
$ ls *trx
my.08120323.trx
$ df[1]=*"trx" ##keeping the filename my.08120323.trx into df[1]
$ echo ${df[1]}
my.08120323.trx ##getting the correct full output
I want $df[1] content - my.08120323.trx to be maintained in any directory that I go.. example below directory.. but I only got *trx value as below when I echo ${df[1]}
$ cd ../..
$ pwd
/u01/abc
$ echo ${df[1]}
*trx ##this is not the output that i expected.. i want it to show my.08120323.trx
$
How do I maintain the value of df[1] to be my.08120323.trx instead of only *trx in any directory I go?
Please shed some light.
Thanks!

DIR(3) 1 DIR(3)
dir - Return an instance of the Directory class
SYNOPSIS
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.
