How to create comma separated list from array in PHP?

Given this array:

$tags = array('tag1','tag2','tag3','tag4','...'); 

How do I generate this string (using PHP):

$tags = 'tag1, tag2, tag3, tag4, ...'; 

Answer 1

Use implode:

 $tags = implode(', ', array('tag1','tag2','tag3','tag4')); 

Answer 2

Yes you can do this by using implode

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

And just so you know, there is an alias of implode, called join

$string = join(', ', $tags); 

I tend to use join more than implode as it has a better name (a more self-explanatory name :D )
