natsort() 函数实现了“自然排序”,即数字从 1 到 9 的排序方法,字母从 a 到 z 的排序方法,短者优先。数组的索引与单元值保持关联。
如果成功,则该函数返回 TRUE,否则返回 FALSE。

<?php $temp_files = array("temp15.txt","temp10.txt", "temp1.txt","temp22.txt","temp2.txt");
sort($temp_files);
echo "Standard sorting: ";
print_r($temp_files);
echo "<br />";
natsort($temp_files);
echo "Natural order: ";
print_r($temp_files);
?>

Standard sorting: Array ( [0] => temp1.txt [1] => temp10.txt [2] => temp15.txt [3] => temp2.txt [4] => temp22.txt ) Natural order: Array ( [0] => temp1.txt [3] => temp2.txt [1] => temp10.txt [2] => temp15.txt [4] => temp22.txt )
