Replace the last comma with an & sign

Question

I have searched everywhere but can\'t find a solution that works for me.

I have the following:

$bedroom_array = array($studio, $one_bed, $two_bed, $t         


        

Answer 1

Pop off the last element, implode the rest together then stick the last one back on.

$bedroom_array = array('studio', 'one_bed', 'two_bed', 'three_bed', 'four_bed');
$last = array_pop($bedroom_array);
$string = count($bedroom_array) ? implode(", ", $bedroom_array) . " & " . $last : $last;

Convert & to the entity & if necessary.
