Question

I would like to wrap all elements of an array with something like but I don’t want a lot of lines or foreach loop

$links = array('london','new york','paris');

The outcome should be

<a href="#london">london</a>
<a href="#new york">new york</a>
<a href="#paris">paris</a>

Answer 1

How about array_map?

$links   = array('london', 'new york', 'paris');
$wrapped = array_map(
   function ($el) {
      return "<a href=\"#{$el}\">{$el}</a>";
   },
   $links
);

Without PHP > 5.3, you can’t use a lambda function, so you’ll need something like this:

function wrap_those_links($el)  { 
      return "<a href=\"#{$el}\">{$el}</a>"; 
}

$links   = array('london', 'new york', 'paris');
$wrapped = array_map('wrap_those_links', $links);
