(PHP 4, PHP 5, PHP 7, PHP 8) array_pad— 以指定长度将一个值填充进数组 说明 array_pad(array $array, int $length, mixed $value): array array_pad() 返回array 的一个拷贝,并用 value 将其填补到 length 指定的长度。如果 length 为正,则填补到数组的右侧,如果为负则从左侧开始填补。如果 ...
(PHP 5, PHP 7, PHP 8) array_udiff—用回调函数比较数据来计算数组的差集 说明 array_udiff(array$array,array...$arrays,callable$value_compare_func):array 使用回调函数比较数据,计算数组的不同之处。和array_diff()不同的是,前者使用内置函数进行数据比较。
在这个问题中,我们需要比较 PHP 中的ORDER BY和sort($array)两种排序方法。 ORDER BY是 SQL 语言中的排序方法,它通常用于从数据库中查询数据并按照某个字段进行排序。ORDER BY是在数据库中完成排序的,因此它的性能取决于数据库的查询性能。 sort($array)是 PHP 中的排序函数,它可以对一个数组中的元素进行排序...
The best way to merge two or more arrays in PHP is to use thearray_merge()function. Items of arrays will be merged together, and values with the same string keys will be overwritten with the last value: 1$array1= ['a' => 'a', 'b' => 'b', 'c' => 'c'];2$array2= ['...
sort modes:* - random: random array order* - reverse: last entry will be first, first the last.* - asce: sort array in ascending order.* - desc: sort array in descending order.* - natural: sort with a 'natural order' algorithm. See PHPs natsort() function.** In addition, this ...
