[SOLVED] foreach question

[izbryte]

I have an array of items that I need to print out. I have it set so that there is a comma after each item.

Here's my current code:

$specialties=explode(",",$row['specialties']);				
foreach($specialties as $fs) {
echo "$fs, ";
}

 

Is there any way that I can remove that last comma?

 

Right now it looks like this

A, B, C, D, E,

I'd like it to look like this

A, B, C, D, E

 

Thanks in advance for any help!

[amites]

so you want to chop that last comma off?

$specialties=explode(",",$row['specialties']);
$max = count($specialties);
$count = 0;

foreach($specialties as $fs){
   $count++;
   if($count == $max)
       echo "$fs";
   else
       echo "$fs, ";
}

use an if statement. if it is not equal to the last $fs (I don't know how many there are) then echo "$fs, "; else echo "$fs";

Why can't you just echo the contents of $row['specialties'], since that already contains a CSV string.

 

If not, do

<?php
echo implode(', ',$specialties);
?>

why not just move it into specialities? since it's already in csv in the db?

your code:

$specialties=explode(",",$row['specialties']);[code]

so why break em apart to rebuild em back into csv?

[code]$specialties=$row['specialties'];[code]
