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<br />";
}
Copy after login

范例2

<&#63;php
$my_array = array("a" => "Dog", "b" => "Cat", "c" => "Horse");
sort($my_array);
print_r($my_array);
&#63;>
Copy after login

返回结果

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

希望本文所述对大家的php程序设计有所帮助。
