Print the values of a flat array as a comma-separated string

Question

I'm trying to print each value in this array as a comma-delimited string.

$domainext = array("com","net","edu","uk","au","in","biz","ca","cc","cd","bz","by");

Here is how I'm doing it.

 foreach ($domainext as $ext){
     $ext = implode(', ', $domainext);
     echo $ext."<br>";
     echo "<br>";
 }

this is the output.

com, net, edu, uk, au, in, biz, ca, cc, cd, bz, by <br>

(however, there are as many lines as there are array values)

I have tried using explode(), and it returns "array" with an error above it.

you dont need $ext = implode(', ', $domainext); inside the loop. — Abhik Chakraborty

I think he wants one domain text on each line due to wrapping each one with <br> — Useless Intern

Why a downvote ? i don't think that's fair since he is stating it's a basic question — Azox

I think this is what you are looking for:

$domainext = array("com","net","edu","uk","au","in","biz","ca","cc","cd","bz","by");

print implode("\n", $domainext);

This gives:

com
net
edu
....

Oops... replace the "\n" by a br tag if you are printing to a web page.

print implode("<br/>", $domainext);

As seen below, join works too. I believe it is an alias of implode.

Just FYI.... implode takes an array and converts to a string. explode takes a string and converts it into an array. The "glue" can be specified for both.

You dont need to implode or explode anything :), try this:

foreach ($domainext as $ext){
        echo $ext."<br>";
        echo "<br>";
    }

If you just want to output the items in your array on a different row, you cna use join

echo join("<br/>",$domainext);

As others have said, no loop necessary.

Simply:

echo join('<br>', $domainext);

will do the job if you want each domain suffix separated with HTML line breaks (the exact required output is unclear from your question). Join is an alias of implode, and preferable from its clearer meaning.
