本文实例讲述了php通过sort()函数给数组排序的方法。分享给大家供大家参考。具体分析如下:

sort()函数用于给数组排序,,本函数为数组中的单元赋予新的键名。原有的键名将被删除。
如果成功则返回 TRUE,否则返回 FALSE。

$alpha = array ("x", "a", "f", "c"); sort( $alpha ); foreach ( $alpha as $var ) { print "$var
"; }

范例2

"Dog", "b" => "Cat", "c" => "Horse"); sort($my_array); print_r($my_array); ?>

返回结果

Array ( [0] => Cat [1] => Dog [2] => Horse )

希望本文所述对大家的php程序设计有所帮助。
