导读:$test1[2] = "one";$test2[1] = "two";$test2[3] = "three";$test = $test1 + $test2;print_r($test); 我已经使用了数组联合运算符,但是当我打印数组时,它的顺序错误. Array ( [2] = one [1] = two [3] = three ) 如何在数组中以数字方式对键进行排序?所以
$test1[2] = "one"; $test2[1] = "two"; $test2[3] = "three"; $test = $test1 + $test2; print_r($test); 我已经使用了数组联合运算符,但是当我打印数组时,它的顺序错误. Array ( [2] => one [1] => two [3] => three ) 如何在数组中以数字方式对键进行排序?所以我得到以下结果. Array ( [1] => two [2] => one [3] => three ) 解决方法
有一个
number of options,取决于你所追求的结果.最简单的是ksort:
$test1[2] = "one"; $test2[1] = "two"; $test2[3] = "three"; $test = $test1 + $test2; ksort($test); print_r($test); 请参阅文档:http://www.php.net/manual/de/function.ksort.php (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
