Php print the multiplication Port absolute table code

Php Tutorial printing multiplication Port absolute table code
Just now, php often asked us to answer this question. Today I will print a multiplication script again.

<? Php

/*
* Print the multiplication Port reject table
*/
Echo "Jiu Ling Jiu multiplication Port limit table <br> ";
Echo "<table> ";
For ($ I = 1; $ I <= 9; $ I ++ ){
Echo "<tr> ";
For ($ j = 1; $ j <= $ I; $ j ++ ){
Echo "<td>". $ j. "*". $ I. "=". ($ j * $ I). "</td> ";
        }
       
Echo "</tr> ";
    }

Echo "</table> ";
   
Echo "<br> ";
Echo "<table> ";
For ($ I = 1; $ I <= 9; $ I ++ ){
Echo "<tr> ";
For ($ j = $ I; $ j <= 9; $ j ++ ){
Echo "<td>". $ I. "*". $ j. "=". ($ j * $ I). "</td> ";
        }
       
       
Echo "</tr> ";
    }

Echo "</table> ";
?>

A simple sum

Function sum ($ n)
{
If ($ n> 1)
        {
Return sum ($ n-1) + $ n;
} Else
        {
Return 1;
        }
}
Echo sum (1, 100 );
