Variable Being Reset in For Loop

I'm trying to increment a variable in a for loop.

<---
$startColumn = 5;
for($rowLength = 0; $rowLength < $length; $rowLength++){
echo "New row current column : " . $startColumn . " ";
$startColumn++;
$newRow[$startRow][] = $startColumn;
echo "New row current column updated: " . $startColumn . " "; }
--->

This outputs:

New row current column :5
New row current column updated:6

New row current column :5
New row current column updated:6...

Why is the $startColumn variable being reset to it's pre-loop value?
How can I increment this value?

Seems to work for me...

$startRow = 0;
$startColumn = 5;
for($rowLength = 0; $rowLength < 10; $rowLength++){
echo "New row current column : " . $startColumn++ . " ";
$newRow[$startRow][] = $startColumn;
echo "New row current column updated: " . $startColumn . " "; }

output:

New row current column : 5
New row current column updated: 6
New row current column : 6
New row current column updated: 7
New row current column : 7
New row current column updated: 8
New row current column : 8
New row current column updated: 9
New row current column : 9
New row current column updated: 10
New row current column : 10
New row current column updated: 11
New row current column : 11
New row current column updated: 12
New row current column : 12
New row current column updated: 13
New row current column : 13
New row current column updated: 14
New row current column : 14
New row current column updated: 15
