Simple version of the "9" multiplication rule table implemented by php, and a "multiplication rule" implemented by php _ PHP Tutorial

Php implements a simple version of The Jiujiu multiplication table, and php implements multiplication. Php implements a simple version of the 9-9 multiplication table, and php implements a multiplication table. the 9-9 multiplication table is also a program question for many interview tests. it examines the logic thinking ability of php interviewers, it is a simple version of the 9-9 multiplication table implemented by php.

The Jiu multiplication table is also a program question for many interview tests. it examines the logic thinking ability of php interviewers, mainly understanding and using algorithms, below is the php code written in php to output the jiujiu multiplication formula:

<?phpfor($i=1;$i<=9;$i++){for($j=1;$j<=$i;$j++){echo “$i*$j=”.$i*$j.' ‘;}echo ‘
';}?>

After reading it, is it very easy? it is two loops, the outer controls the number of rows in the loop, and the inner controls the number of inputs in each row.

Output result:

How to use PHP for 99 multiplication formulas

The following program passes debugging to ensure that it runs correctly:

For ($ I = 1; $ I <= 9; $ I ++ ){
For ($ j = 1; $ j <= $ I; $ j ++) echo "$ I * $ j =". $ I * $ j ."";
Echo"
\ N ";
}
?>

The running result is as follows:
1*1 = 1
2*1 = 2 2*2 = 4
3*1 = 3 3*2 = 6 3*3 = 9
4*1 = 4 4 4*2 = 8 4*3 = 12 4*4 = 16
5*1 = 5 5*2 = 10 5*3 = 15 5*4 = 20 5*5 = 25
6*1 = 6 6*2 = 12 6*3 = 18 6*4 = 24 6*5 = 30 6*6 = 36
7*1 = 7 7*2 = 14 7*3 = 21 7*4 = 28 7*5 = 35 7*6 = 42 7*7 = 49
8*1 = 8 8*2 = 16 8*3 = 24 8*4 = 32 8*5 = 40 8*6 = 48 8*7 = 56 8*8 = 64
9*1 = 9 9*2 = 18 9*3 = 27 9*4 = 36 9*5 = 45 9*6 = 54 9*7 = 63 9*8 = 72 9*9 = 81

Php 9-9 Multiplication table

This is simple. for more information, see add a while loop to the for loop.
Echo "multiplication table", "</br> ";
For ($ j = 1; $ j <= 9; $ j ++ ){
$ Z = 1;
While ($ z <= $ j ){
Echo $ z. "*". $ j. "=". $ z * $ j ,"";
$ Z ++;
}
Echo "</br> ";
}
?>

The multiplication formula table is also a program question for many interview tests. the logic thinking ability of php interviewers is mainly...
