How can I easily remove the last comma from an array?

Question

Let\'s say I have this:

$array = array(\"john\" => \"doe\", \"foe\" => \"bar\", \"oh\" => \"yeah\");

foreach($array as $i=>$k)
{
echo $i.\'-\'.$         


        

Answer 1

One method is by using substr

$array = array("john" => "doe", "foe" => "bar", "oh" => "yeah");

$output = "";
foreach($array as $i=>$k)
{
    $output .= $i.'-'.$k.',';
}

$output = substr($output, 0, -1);

echo $output;

Another method would be using implode

$array = array("john" => "doe", "foe" => "bar", "oh" => "yeah");

$output = array();
foreach($array as $i=>$k)
{
    $output[] = $i.'-'.$k;
}

echo implode(',', $output);
