These days I found that some children's shoes still have some problems in outputting the multiplication table. Today I will give you a detailed explanation...
First, let's look at the Code:For ($ I = 1; $ I For ($ j = 1; $ j Echo "$ j x $ I =". $ j * $ I ."";}Echo "}?>Output result:
Well, let's further analyze:
We call the outermost loop a "Trip ":
First trip:
$ I is 1, meeting $ I
While the inner loop $ j satisfies $ j
$ J auto-increment 1, no longer meet $ j
Output "

: This article mainly introduces the daily php 3-21 design of a 9-9 multiplication table. if you are interested in the PHP Tutorial, refer to it.
Different from the table above, there are more restrictions on the number of columns in each row.
That is, the first row and the second row and so on.
So

For loop continuous summation, 9-9 multiplication table code. A typical example of a for loop is continuous summation: 1 + 2 + 3 + ...... + 100. after talking for more than an hour, some students still don't. Some people have to think about the program. some people keep typing on the keyboard, and the classic example of for loop is continuous summation: 1 + 2 + 3 + ...... + 100. after talking for more than

1. What is an exception?
Exceptions are errors in the program, such as array out-of-bounds and NULL pointer access. In Java, everything is an object, and exceptions are no exception. All exceptions are an instance object derived from the Throwable class.
Ii. Exception Classification
In the exception field, there are two major genres. One cla

The rule is: Check the trend of the 9-9 multiplication table, determine the for loop of the outermost layer, and check the column changes: from 1 to 9, or 9 to 1.
