在上述示例代码中,我们定义了一个`sortMultidimensionalArrayByValue()`函数来对多维数组按照指定的列进行排序。函数参数`$array`表示要排序的数组,`$column`表示要排序的列,`$order`表示排序的顺序,默认为升序。 在函数内部,我们使用`foreach`循环遍历原始数组,并将要排序的列的值提取出来放到`$sortColumn`数组中。

Similar to this, we have another function array_unshift($arr, $val) to add a new value($val) at the start of the array(as the first element).sort($arr)This function sorts the array elements in ascending order. In case of a string value array, values are sorted in ascending ...
* be `$array['x']['y']['z']` or `$array->x->y->z` (if `$array` is an object). If `$array['x']` * or `$array->x` is neither an array nor an object, the default value will be returned. * Note that if the array already has an element `x.y.z`, then its value...

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 length 的绝对值小于或等于 array 数组的长度则没有任何填补。 参数...

Here are a few advantages of using multidimensional array in our program/script: Detailed information can be stored in multidimensional array. On top level, it can either be kept indexed or associative, which makes it more user-friendly, as they can use it as per their requirements. ...
