Question

I have a multidimensional associative array that I run through and grab a specific value that is then echoed out.

foreach ($multi_array as $entry) {

   echo $entry['tag_id'];

}

It echos 12. What function could I use to convert it to…

`1`,`2`

Answer 1

You are looking for the implode function, try this:

$result = '`' . implode('`,`', $multi_array) . '`';
