note 52363 deleted from function.implode by hholzgra

Note Submitter: Andy Morris ---- Similar to a previous note, but this works for any length array, plus also works for arrays with key strings instead of integer keys! I know it's not strictly an implode() example, but it concerns what you might be considering using implode() to help you to do achieve... <?php // Return array as a comma separated list; final two elements separated // by 'and' with an optional "Oxford" comma preceding the 'and'. function english_list($array, $oxfordComma=0) { $optionalComma = ( $oxfordComma ) ? "," : ""; $str = ""; $size = count( $array ); $i = 0; foreach ( $array as $item ) { $str .= $item; $i++; if ( $i < $size - 1) $str .= ", "; elseif ( $i == $size - 1) $str .= $optionalComma." and "; } return $str; } // test the comma separated list function echo english_list( array(), 1 )."<br>"; echo english_list( array("foo"), 1 )."<br>"; echo english_list( array("foo", "bar"), 0 )."<br>"; echo english_list( array("a" => "foo", "b" => "bar", "c" => "foobar"), 1 )."<br>"; echo english_list( array("foo", "bar", "foobar", "barfoo"), 0 )."<br>"; ?>
