让theme_item_list生成的列表更易读
theme_item_list 函数是用于生成主题样式UL、OL等列表，然而在生成这些代码时会发现代码是不会换行的，象<ul><li>...</li><li>...</li></ul>
这篇文章 Add newlines to theme_item_list 指导我们轻松的解决这个问题，对于像我这样不会写代码的人来说帮助不小。
修改的宗旨保证核心代码不变动，复制 includes\theme.inc 行915 - 969粘贴在你的主题template.php文件中
/**
* Return a themed list of items.
*
* @param $items
* An array of items to be displayed in the list. If an item is a string,
* then it is used as is. If an item is an array, then the "data" element of
* the array is used as the contents of the list item. If an item is an array
* with a "children" element, those children are displayed in a nested list.
* All other elements are treated as attributes of the list item element.
* @param $title
* The title of the list.
* @param $type
* The type of list to return (e.g. "ul", "ol")
* @param $attributes
* The attributes applied to the list element.
* @return
* A string containing the list output.

将function theme_item_list($items = array(), $title = NULL, $type = 'ul', $attributes = NULL) {
改写为：
function phptemplate_item_list($items = array(), $title = NULL, $type = 'ul', $attributes = NULL) {
当然也可是function phptemplate_item_list2之类的，我们在调用时，把原theme_item_list改成你的名字，如：phptemplate_item_list2
另外在这个函数中
if (count($children) > 0) {
$data .= theme_item_list($children, NULL, $type, $attributes); // Render nested list
}
$data .= theme_item_list($children, NULL, $type, $attributes); // Render nested list
}
根据需要改写$data .= theme_item_list
