Build comma separated string in PHP Loop

Question

Hello Guys i need to do this,

I have a common loop

foreach ($stuffs as $stuff) {
echo $stuff;
}

Lets assume $stuff is an \'id\' of a my

Answer 1

Should be as simple as:

$string = implode(",",$stuffs);
echo $string

Answer 2

This worked in my case (detects if isn't the loop last iteration):

foreach($array as $key => $val){
    ...
    if($key!==count($array)-1){echo ',';}
}

Answer 3

If you really wanna have the loop:

$values = "";

foreach ($stuffs as $stuff) {
    $values != "" && $values .= ",";
    $values .= $stuff;
 }

echo $values;

I suggest using implode, but the loop can really give you more power if you wanna do some further stuff.

Answer 4

implode should be the tool:

implode(",", $stuffs);

will return a comma separated list.

Test

$myarray=array(1,2,"hello",4,5);
echo implode(",", $myarray);

returns

1,2,hello,4,5
