Php assigns values to arrays (two-dimensional arrays)

In php, array assignment is simple. If one-dimensional array assignment is easier than two-dimensional array assignment or multi-dimensional array assignment, I will introduce various examples of array assignment, for more information, see.

What about PHP array assignment? As follows:

Example 1: One-dimensional array assignment

The Code is as follows:	Copy code
$ My_array = array (); $ My_array [] = "www" $ My_array [] = "helpphp "; $ My_array [] = "cn ";

Destroy An Array

The Code is as follows:	Copy code
Unset ($ My_array [0]; Unset ($ My_array );

Example 2: Two-dimensional array assignment

The Code is as follows:	Copy code
$ Data_array = array ($ total, 2); // $ datarows indicates the number of records obtained from the query. $ Data_array [$ I] [2] = $ Area; // error message: Cannot use a scalar value as an array

The specific cycle is as follows:

The Code is as follows:	Copy code
$ I = 0; While ($ result = $ db-> fetch_array ($ query )) {$ Area = $ result ["Area"]; $ Data_array [$ I] [2] = $ Area; // error! $ I = $ I + 1; }
