Dimension-adaptive elements are centered vertically horizontally:If the size of the child element is fixed, then it is easier to set it to vertical horizontal centering, which is not introduced here, specifically, you can refer to the CSS implementation div Horizontal Vertical Center code chapter. If the dimensions of the child elements are not fixed, then setting them to center vertically is a bit cumbersome, as shown in the following code example:DO
PHP Judgment Array Dimension (encapsulated function)
Sometimes need to judge the dimensions of the array, surfing the internet to find a lot of things similar to the wording, rambling and do not understand what the meaning of. Here's what I wrote:
private static function array_depth($array) { if(!is_array($array)) return 0; $max_depth = 1; foreach ($array as $value) { if (is_array($value)) { $depth =
Question: If a user gives a dimension and prints a specified matrix, for example, if the user gives 10, the output should be shown in: The procedure is as follows: # Include Program running result:
Thinkphp converts a two-dimensional array into a one-dimensional array method applicable to tags. thinkphp dimension
This example summarizes Thinkphp's one-dimensional array method for converting a two-dimensional array into a tag. Share it with you for your reference. The specific implementation method is as follows:
Method 1:

Php implements the method of adding values to all one-dimensional arrays in a two-dimensional array. the dimension of the Two-dimensional array
This example describes how php adds values to all one-dimensional arrays in a two-dimensional array. We will share this with you for your reference. The details are as follows:
Add values (indexes and associations) to all one-dimensional arrays in a two-dimensional array)

can PHP load the value of a column in MySQL into an single-dimension array?
For example, table name

As above, for example, the field class this column, loaded into a single-dimensional array!
The default mysql_fetch_array is to load the rows into an array, and now I want to load a column into an array

Method One: Use the array map () method, which runs the given function for each item in an array, and returns a list of the results of each function call.var arr = [1,[2,[[3,4],5],6]]; function Unid (arr) { var arr1 = (arr + '). Split (', '); Convert the array to string and then comma-delimited to array var arr2 = Arr1.map (function(x) { return number (x); }); return arr2;} Console.log (Unid (ARRA));Law II: Using apply combined with concat, the disadvan
