For Web programming, the most important thing is to access and read and write data. There may be many ways to store them, such as strings, arrays, files, and so on. arrays, which can be said to be a more important way of using PHP data. PHP's Array
1. The concept of arrays
An array is a named range that is used to store a series of variable values.
Each array element has an associated index (also a keyword) that can be used to access elements.
PHP allows you to use numbers or strings evenly
Ange ($low, $high), Range ($low, $high, $step);//Create an array of sequential values such as: Range (1,4) as (1,2,3,4) and range (' A ', ' Z ')
Each ($array) returns the current element of the array sequentially, and sets the next element to the
PHP operation array functions. Ange ($ low, $ high), range ($ low, $ high, $ step); create an array of sequential values, for example, range () is) for example, range (a, z) each ($ array) returns the current element of the array in sequence, and

Each ($array) returns the current element of the array sequentially and sets the next element to the
1. Merging Arrays
The Array_merge () function merges the arrays together to return an array of unions. The resulting array starts with the first input array parameter, forcing it sequentially in the order in which the array parameters appear later.
