About arrays:
Arrays in PHP are complex and are more flexible than arrays in many other high-level languages.An array of arrays is an ordered set of variables in which each variable is called an element.Arrays can be numbered or associated, that is,
js|jscript| operations
Operator Precedence in JScript is a set of rules. This rule controls the order in which operators are executed when evaluating an expression. Operations with higher precedence are performed Fuxian to lower-priority operators.
Two-dimensional array, multidimensional array, string array;

The concept of a two-dimensional array: An array of two subscripts following an array name is called a two-dimensional array

An array is a set of elements of the same data type arranged in a certain order, that is, a variable of the same type is named with a name and then numbered to distinguish their set of variables, which is called an array name, and the number is
A new restrict-decorated pointer is added to the C99:
A pointer decorated by restrict is the first way to access the object that the pointer points to.An object can be accessed only if the second pointer is based on the first.Access to an object is
To define an array value:
The difference between an array variable and a scalar variable can be explained as follows.
Say that you are trying to show the names of various students as variable sets. Each individual variable is a scalar variable, as
1. Array Processing:
1.1 Creation and initialization of arrays:
The 1.arrary () function creates an array, by default 0 elements are the first element of the array,
Count () and sizeof () function to get the number of data elements
2. Using
1, array does not require all element uniform type, does not support typed array
var i:int=23;
var array:array=[122,i, "Asdfasdf", "ASDFASDFASDF"];
2. Initialize and access array elements
Slightly
3, the length of the array
The length of the
Unsure of the order of operations for the following expressions?A>b?c:d+eA&&b==cThe following table is clear, the following table is listed by priority from highest to lowest, with the same priority evaluated in left-to-right order.
1. arrays in PHP Instead of interpreting the array in PHP as an array in our narrow sense, I think we may also split this array into two parts. One is our regular array, and the other is our Dictionary.2. Create an arrayIf the array does not exist,

C pointer 4: pointers and arrays, and c pointer Arrays
Arrays are the basic data structures built in C. array representation and pointer representation are closely related. A common mistake is that arrays and pointers are completely interchangeable.
The array in PHP is an ordered ing (1-to-1 relation key-value ). Array is a combination of arrays, dictionaries, and collections. The key can be int or string. Value can be of any type. The key is forcibly converted as follows: 1. A string integer
The difference between a pointer and an arrayPointers and arrays can access array elements by means of subscripts and pointers (p+i)1. Pointers can be modified to point toThe array name is a constant that represents the address of the first element
Pointer is a pointer, pointer variable in the system, will always account for 4 byte , its value is the address of a certain memory. The pointer can point to anywhere, but not anywhere you can access it through this pointer variable. an array is
