    Newbie problem with arrays

    I've got this:

    PHP Code:
    <?php

    $names     = array("Abraham", "Beth", "Christina", "David", "Ellen", "Fergus", "Goliath", "Hamish")

    ?>

    <html>
    <body>
    <p>I live next to 

    <?php 

    echo $names[0] . " ," $names[1] . " ," $names[2] . " ," $names[3] . " ," $names[4] . " ," $names[5] . " ," $names[6] . " and " . $names[7] . ".";

    ?>

    </p>
    </body>
    </html>

    But when I run it, only "I live next to" shows up... Why?


    Regards,

    Always Use a DOCTYPE!
    Always Use * {margin: 0; border: none; padding: 0;} in the top of your CSS stylesheet.
    Always Use only CSS for layout; never (X)HTML.

    You need to loop through the array and echo each value. Use foreach for it

    PHP Code:
    <?php 

    foreach($names as $name)
    {
        echo     $name .", ";
    }

        You are missin some concatenators (decimals, periods, whatever you want to call them):
        PHP Code:
        echo $names[0] . " ," . $names[1] . " ," . $names[2] . " ," . $names[3] . " ," . $names[4] . " ," . $names[5] . " ," . $names[6] . " and " . $names[7] . "."; 
        ... as well as a semi-colon after the $names array. error_reporting should have pointed this out.

          Thanks I always wondered what they were called. Although i think it's concatenates. Not that I'll probably remember that word
          You can not say you know how to do something, until you can teach it to someone else.

            The missing concatenates was what was missing. Thanks

              This code could easily be simplified to handle any number of names. You're currently assuming a fixed name count.
              PHP Code:
              $names = array( /* array of names */ );

              switch (               count( $names ) )
              {
                  case               0:
                                    $names = 'no one';
                      break;
                  case               1:
                                    $names = reset( $names );
                      break;
                  default:
                                    $last = array_pop( $names );
                                    $names = implode( ', ' $names ) . ' and ' . $last;
              }

              echo               'I live next to ', $names, '.';
              // I live next to no one.
              // I live next to Abraham.
              // I live next to Abraham, Beth, Christina, David and Ellen.
