php开发之数组排序
数组相对于其他变量类型的优点之一是,能够对它们进行排序。PHP包括多个用于对于数组排序的函数,它们的语法都很简单:
$names=array("Moe","Larry","Curly");sort($names);
这些排序函数执行3种排序。首先,可以使用sort()函数按值对数组排序,并丢弃原来的键。重要的是理解排序过程之后将会重置数组的键,因此如果键-值这一关系很重要,就不应该使用该函数。
其次,可以使用asort()函数按值对数组排序,同时还会维持键。最后,可以使用ksort()函数按键对数组排序。如果把这些函数分别改为rsort(),arsort()和krsort(),则能够以相反的顺序对数组排序。
