将数组作为字符串

Question

I have a array:-

Array ( [6] => 1 [6(HL)] => 3 [5] => 1 [7(HL)] => 2 )

How to break it and echo as like this:-

2(6), 3(6(HL)), 1(5), 2(7(HL))

I have try to use implode to break it as a string, but this is what result I get:-

2, 3, 1, 2

any idea on this?

Thanks for advance.

Answer 1

assume your array is $arr :

$output = '';
foreach($arr as $k => $v) {
  $output .= $v . '(' . $k . ')' . ', ';
}
$output = substr($output, 0, strlen($output)-2);
echo $output;
