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

strrpos finds the last occurrance of a specified string. $str = '1, 2, 3';

$index = strrpos( $str, ',' ); 
if( $index !== FALSE )
    $str[ $index ] = '&';
