foreach statement rewrite last element?

Im using foreach as below

 foreach($album as $a) { 

$string .= $a['value'].', ';

 }

 echo $string;

which returns something like 

  1, 2, 3,

etc

now how do I remove the , from the last loop.

So $string returns 1, 2, 3

You can use rtrim() to do this 

rtrim($string, ',');
echo $string;

should do the job.

Easiest way:

foreach($album as $a){ 
    $string .= $a['value'].', ';
}

$string = substr($string, 0, -2);
echo $string;

if you don't want to use implode(), which is the best method, you can create a temp var:

foreach($album as $a){ 
    $string .= $addStr . $a['value'];
    $addStr = ',';
}

Try:

$string = preg_replace('#, $#', '', $string);

A for loop would be better suited in this case, so that you could just avoid adding it for the last element.

But you can just trim the string to the right.

You could use implode():

$values = array();
foreach ($album as $a){
  $values[] = $a['value'];
}

$string = implode(',', $values);

$first = TRUE;
$string = '';
foreach($album as $a) {  
    if ($first) {
        $first = FALSE;
    } else {
        $string .= ', ';
    }
    $string .= $a['value']; 
}

Maybe you could do something like this:

$value = array();
foreach($album as $a) { 
    array_push($value, $a['value']);
 }

echo join(',', $value); // join by comma
