I could do so
$array = array(12, 14, 121, 123);
$var = $array[0].", ".$array[1].", ".......
echo $var
But how to do it if I don’t know the exact size of the array?
'Cause I’m getting her through a post that comes from a <select multiple="multiple"></select>
So you can’t tell the exact size of it.

This is probably what you want:
$array = array(12, 14, 121, 123);
$var = "";
foreach ($array as $item) $var .= $item . " ";
echo $var;
Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
Composite allocation operator’s manual.
This way you sweep all the elements. There are several other ways to get the same effect, but this is the most appropriate.
In this specific case you can do something simpler:
implode($array, ", ");
Thanks! I didn’t know operator yet .= haha. But it worked perfectly here!
That one implode did in a row what my code did in almost 10 kkkk living and learning.

Another solution, formatting the way you suggested in the question, with comma:
$array = array(12, 14, 121, 123);
$newVar = "";
$arrayLength = count($array);
for($i = 0; $i < $arrayLength; $i++){
if($i == ($arrayLength-1)){
$newVar .= $array[$i];
}else{
$newVar .= $array[$i].",";
}
}
echo $newVar;
To add the commas I did so, Diego : $var.=" , ". $item; And at the time of printing, I used substr() starting at 2
@Naldson what do you mean? I don’t understand.

@Very cool naldson, so you don’t need to mess with Dice from hehe array
@Naldson your code doesn’t make sense.
@bigown So it is... After I came to see that it is best to just use the "implode($array, ", ");"

So make it simpler:
$array = array(12, 14, 121, 123);
foreach ($array as $item) {
echo "<br>".$item;
}

Ever tried foreach?

Excuse me... But how? In the way I am thinking there is no way to keep all values.... But always the last inserted...
