list...Elliminating values to the right of a comma

i have a long two column list separated by a comma like this:

fefewfewf,efewfew
eeeeee,ggggg
rgrgrr,gggrrrr

i want to eliminate the values to the right of the comma for each column so it looks like:

feferfef,
ferferer,
rgrgergrt,

how is this done with php?

 

You can use the explode function. See www.php.net/manual/en/function.explode.php

 

$temp = explode(",", "fefewfewf,efewfew");

$new = $temp[0] . ",";
