PHP智能自然排序natsort()函数
<?php/*
* natsort:自然排序，根据字母与数字的组合方式进行排序比较
* sort()函数中 file14 < file2，因为第4位前者1小于后者2
* natcasesort():忽略大小写
*/
$array = array("file.txt", "File1.txt", "file14.txt", "file13.txt", "file2.txt");
print_r($array);
echo "<br/>";
natsort($array);
print_r($array);
echo "<br/>";
natcasesort($array);
print_r($array);
echo "<br/>";
输出结果：
Array ( => file.txt => File1.txt => file14.txt => file13.txt => file2.txt )
Array ( => File1.txt => file.txt => file2.txt => file13.txt => file14.txt )
Array ( => file.txt => File1.txt => file2.txt => file13.txt => file14.txt )
Array ( => file.txt => File1.txt => file2.txt => file13.txt => file14.txt )
