help - sorting strings and eliminating duplicates

[wer0ckz]

Hi. Please help me.

 

I need an example of codes maybe 4-6 lines:

 

example for code for small program that sorts the following string, eliminating duplicates. The string is: a, b, rt, tril, drv, b, span, drv, art, arc, d, a, drc

 

Thank you

We don't write code for you. We help you with code you've already written. This and the other post you made look like homework problems.

I had some free time.

 

<?php
$string = "a, b, rt, tril, drv, b, span, drv, art, arc, d, a, drc";
$string_array = explode(", ",$string);
asort($string_array);
$string_array = array_unique($string_array);
foreach ($string_array as $string_single){
$string_single = trim($string_single);
echo "$string_single<br />";
}
?>

 

Results would be:

a

arc

art

b

d

drc

drv

rt

span

tril

Since someone already answered you, here's another way:

<?php
$str = 'a, b, rt, tril, drv, b, span, drv, art, arc, d, a, drc';
$ary = array_unique(explode(', ',$str));
sort($ary);
echo implode("<br>\n",$ary) . "<br>\n";
?>
