[fernandodonster]

<?
$mystr ="value 1 for 'a',value 2 for 'b',value 3 for'g'";
//I want to display the string $rrr as reverse,that is output should be like "value3 for'g',value 2 for 'b',value 1 for 'a'"
?>
thanks in advance

Use [man]explode/man to split the string by commas, then [man]array_reverse/man to perform the reverse, then [man]implode/man to join it back with commas.

NB: Post #8000 🙂

Untested:

echo implode(',', array_reverse(explode(',', $mystr)));

Ive always used implode() without any separating string. example:

$test=array("1","2","3");
$together=implode($test)

The code works for me, but should I be writing it more like this?

$test=array("1","2","3");
$together=implode("", $test)

Just curious...

See the first "Note" and the "Parameters" section of the [man]implode/man page. Pretty much explains why it works either way, and that the preferred method is to use the implode(glue, array) prototype to avoid confusion.
