Question

I have an array $x = array(a,b,c); Each element of the array is a url.

There is a function link($x[$i]) which converts every element of the array into a hyperlink.

function convert($x){
 $new = explode(',',$x);
 for($i=0;$i<count($new);$i++){
   echo  link($new[$i]);  // converts the url to hyperlink
 }

This displays the output as url1 url2 etc. But wht if i want the comma ',' between the 2 urls. How do i get that, without the comma ',' being part of the hyperlink?

desired output would be

hyperlink1 , hyperlink2 etc  // note comma ',' should not be part of the hyperlink

You can use the array_map and implode functions to make this easy.

$urls = array('http://www.google.com/', 'http://www.stackoverflow.com/');

$links = array_map("link", $urls);
echo implode(', ', $links);
