10 * foreach ($myLinks as $link)
11 * echo $link['title'].' at url '.$link['url'].'; description:'.$link['description'];
12 *
13 * Available keys:
14 * - description: description of the entry
15 * - linkdate: date of the creation of this entry, in the form YYYYMMDD_HHMMSS
16 * (e.g.'20110914_192317')
17 * - private: Is this link private? 0=no, other value=yes
18 * - tags: tags attached to this entry (separated by spaces)
19 * - title Title of the link
20 * - url URL of the link. Can be absolute or relative.
21 * Relative URLs are permalinks (e.g.'?m-ukcw')
22 *
23 * Implements 3 interfaces:
24 * - ArrayAccess: behaves like an associative array;
25 * - Countable: there is a count() method;
