This article mainly introduces PHP to modify the array key name method, involving PHP for array traversal, interception, conversion and other related operations skills, the need for friends can refer to the following
This article describes how PHP modifies the array key names. Share to everyone for your reference, as follows:
$ar = Array (Array (1 = ' a ', 2 = 3, 4 = ' long ', 5 = ' zzz ', 6 = ' kkk ', 7
This chapter continues to describe the remaining tables that have not been involved. To this end, create a separate program to describe each different table. Finally, in the last chapter of the book, place them in a separate program, where each table is cross-referenced.
Table 4-1
The first program in this chapter uses the fields table. Enter the following code in the B. CS file and compile the file.
