 # Combinations of numbers

Hey guys, I have been trying to figure this out for a bit and it’s really been stumping me.

I am trying to find every combination of 6 numbers that = x.

All numbers must be between 1 and 49 so the smallest number would be 21 (1 + 2 + 3 + 4 + 5 + 6) and the largest 279 (44 + 45 + 46 + 47 + 48 + 49)

Example:

Every combination of numbers a + b + c + d + e + f that equals 150

I’m thinking I can do it with a dozen do while loops

Example:

``````                     \$one = 1;
\$two = 2;
\$three = 3;
\$four = 4;
\$five = 5;
\$six = 6;
//\$num = 1;

do {
\$total = \$one + \$two + \$three + \$four + \$five + \$six;
\$set = 1;
echo "<tr>";
echo "<td>" . \$one . "</td>";
echo "<td>" . \$two. "</td>";
echo "<td>" . \$three . "</td>";
echo "<td>" . \$four . "</td>";
echo "<td>" . \$five . "</td>";
echo "<td>" . \$six . "</td>";
echo "<td>" . \$total . "</td>";
echo "<td>" . \$set . "</td>";
echo "</tr>";
\$six++;

\$num++;
}while(\$six < 49);

do {
\$total = \$one + \$two + \$three + \$four + \$five + \$six;
\$set = 2;
echo "<tr>";
echo "<td>" . \$one . "</td>";
echo "<td>" . \$two. "</td>";
echo "<td>" . \$three . "</td>";
echo "<td>" . \$four . "</td>";
echo "<td>" . \$five . "</td>";
echo "<td>" . \$six . "</td>";
echo "<td>" . \$total . "</td>";
echo "<td>" . \$set . "</td>";
echo "</tr>";
\$five++;

\$num++;
}while(\$five < 48);``````

Etc, etc but there has to be a simpler way.

Thanks for any kind of help. Cheers!

Hi there,

This seemed to work for me:
[php]
if(isset(\$_POST[‘target’]) && is_numeric(trim(\$_POST[‘target’])))
{
\$target = (integer)trim(\$_POST[‘target’]);
\$middle = floor(\$target/6);
\$range = range(\$middle-2,\$middle+3);
if(array_sum(\$range) == \$target)
{
echo implode(" + “,\$range).” = ".\$target;
}
else
{
echo “cant be done”;
}
}
[/php]
