如何将2个字符串与分隔符连接在一起？ [关闭]

Question

I have a string like this $value[0] = "8000297c - 1360598144 "

I explode them into 2 pieces by doing this : $elements = explode('-', $value[0]);

Then I created 2 variables to store them :

$first = strtolower($elements[0]); // 8000297c 
$last  = strtoupper($elements[1]); // 1360598144

Now- after formatting them, I want to join them back to the original format like this

• $first."-".$last

I was thinking to use implode() function, and I tried

• $polish_sku = implode("-", $first, $last); - then, I got this :

I hope someone don't mind and point out what I did wrong. :D

Answer 1

if you want to use implode

implode("-", array($first, $last));

or just concat them ?

$first . "-" . $last

or use printf/sprintf ?

printf("%s-%s", $first, $last)
