Removing value from echo

[Andrew R]

Sorry for the badly described topic, don't know how else to explain it 

 

For example.  If had the following coordinates in the database:

 

-5.717979 54.728432,-5.672246 54.757900,-5.621388 54.786976,

 

If I then echo them how would I remove the , (comma) at the end?  As I will echoing multiple coordinates from the database, some longer than others I can't simply remove the comma after a certin about numbers.

 

Any help would be appreciated. 

 

Cheers

http://php.net/explode will help.

Thanks 

 

Tryed this, doesn't seem to work though:

 

<?php 
$total = "-5.717979 54.728432,-5.672246 54.757900,-5.621388 54.786976,-5.564545 54.816902,-5.502621 54.848289,-5.436880 54.881577,-5.370000 54.915535,-5.302828 54.949612,-5.234945 54.984013,-5.166701 55.018578,";

$result = explode("$total,", $total);

echo $result[0];

php?>

 

It should select all values excluding the last comma?

[MmmVomit]

$result = explode(",", $total);

Thanks very much  The thing is I only need to remove the very last comma.  So basically I want to select everything before the very last comma.

 

Thanks
