What about PHP array assignment? As follows:

Destroy an array

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

Example 2: Two-dimensional array assignment

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