array question..

If I have an array

DGN, DGN, TEST, TEST3,TEST3, TEST4, TEST4

and this is being transferred to a text box.

How can I remove the duplicate entries?

Example code:

//While the URL is passing the cc string
// DGN, DGN, TEST, TEST3,TEST3, TEST4, TEST4

$cc = $_GET['cc'];

PHP:

<input name="ccc" type="text" value="<?php echo "$cc";?>"/>

HTML:

Any and all help with this would be greatly appreciated. I been racking my head around and think I have been over thinking this for to long that I cant figure it out.

use the array_unique($array) function which is built into php. It removes all duplicate values from an array.

$cc = array_unique($cc);

PHP:

 

tried it.

//While the URL is passing the cc string
// DGN, DGN, TEST, TEST3,TEST3, TEST4, TEST4

$cc = "DGN, DGN, TEST, TEST3,TEST3, TEST4, TEST4";
print_r($cc);
echo "<BR>";
$cc = trim($cc);
print_r($cc);
echo "<BR>";
$c = explode(" , ", $cc);
print_r($cc);
echo "<BR>";
$cc = array_unique($cc);
print_r($cc);

PHP:

doesnt work.

 

It does work. The real issue here is that you are not using descriptive variable names which makes debugging code a nightmare. Try this:

<pre><?php

$myString = "DGN,DGN,TEST,TEST3,TEST3,TEST4,TEST4";
print_r($myString);
echo "<BR>";
$myString = trim($myString);
print_r($myString);
echo "<BR>";
$myArray = explode(",", $myString);
print_r($myArray);
echo "<BR>";
$myArray = array_unique($myArray);
print_r($myArray);

thank you.

Now while it shows

Array
(
    [0] => DGN
    [1] => DGN
    [2] => TEST
    [3] => TEST3
    [4] => TEST3
    [5] => TEST4
    [6] => TEST4
)

Array
(
    [0] => DGN
    [2] => TEST
    [3] => TEST3
    [5] => TEST4
)

Code (markup):

How can I get the second set to display together as
DGN, TEST, TEST3, TEST4

shown as $cc = DGN, TEST, TEST3, TEST4;

to be able to display it in the form text area?


And again I do appreciate all the help guys and gals.
