对于另一个函数,我有一个回调函数,它循环遍历我博客中一篇文章的评论。我现在尝试切换到“线程/嵌套”注释,因此扩展了回调函数。到目前为止,一切都正常,但我无法摆脱这种感觉,即我没有按照最佳php-实践(和性能)编写它。
我使用一个css框架,并必须对分配给单个注释的.span-xy类做一些计算。我从一个全局常数的输入值开始,然后输出。span-12表示父注释。然后,我必须降低/提高每+/- (int) 1对每级嵌套的值。因此,我开始构建数组,对它们进行计数,迭代并为每个注释构建临时数组。
问题:有更简单的方法来解决这个问题吗?

只是快速扫描后的一些一般性评论。它处理编码,而不考虑功能。
$GLOBALS['comment'] = $comment;你为什么要把这个放到全球范围?这可以覆盖现有的全局变量。在这里通过引用传递可能更合适。
static $width = MY_GLOBAL_WIDTH_CONSTANT;为什么这个是静态的?价值是不变的,所以没有必要保留。
if ( $parent > (int) 0 )
[...]
$span_txt = $span - (int) 2;
[...]
$push = $parent_counter != (int) 0 ? 'push-1' : '';不需要将int文字转换为int。如果您希望进行int比较,则应该将其转换为变量。
if ( ! (array) $ancestors )
$ancestors = array();如果为空数组,则为空数组?只需做!isset($ancestors)
