Syntax: startingvalue1; startingvalue2; startingvaluen; while((endingvalue1)&&(endingvalue2)&&(endingvaluen)) { statement1; statement2; statementn; stepvalue1; stepvalue2; stepvaluen; }For the sake of example I will be using while statement in PHP.
Example:
<?php $intcount1=1; $intcount2=10; $intcount3=21; while(($incount1<=10)&&($intcout2>=1)&&($intcount3<=30)) { echo "$intnum1 $intnum2 $intnum3 "; $intcount1++; $intcount2--; $intcount3++; } ?>The script above produces the following outputs:
1 10 21
2 9 22
3 8 23
4 7 24
5 6 25
6 5 26
7 4 27
8 3 28
9 2 29
10 1 30
You can use this as a good alternative for nested loops. Or if you wanted to hit several birds in one stone, that is, several outputs in one looping statement.
