I am doing a program that makes successive numbers from 10 to 1 pairs, odd and multiples of five, but does not throw anything at me and I do not understand how it causes the result to look down as columns:
10 2 3 1
9 4 5 5
8 6 10
7 8 11 15
This is the code:
<?php
$sucesivo=11-$i;
$pares=$i * 2;
$impares=$i * 2 - 1;
$quintos=$i * 5 -5;
for($i=1; $i<=10; $i++){
echo $sucesivo,$pares,$impares,$quintos;
}
?>
Solved.
$i does not exist when you are using it on the first line of your code.
<?php
$i=1;
$sucesivo=11-$i;
$pares=$i * 2;
$impares=$i * 2 - 1;
$quintos=$i * 5 -5;
for($i; $i<=10; $i++){
echo $sucesivo,$pares,$impares,$quintos;
}
?>
In fact, the same thing happened to you in a question that I solved yesterday: Link
