PHP nested for loop skipping every 2nd number - php

Question

I am trying to get 2 simple for loops. The first for loop cycles through results from the database. The 2nd for loop prints out a table for each store based on the amount of weeks selected.
My code looks as follows
$retval = f_select_query($query_select_stores, $datarows);
$rowcount = count($datarows);
for ($counter = 0; $counter< $rowcount; $counter++) {
$store_name = $datarows[$counter]->store_name;
echo '<table style="width: 100%; border:1px solid black;">';
echo '<tr>';
echo '<th style="border: 1px solid black;">' . $store_name . '</th>';
for ($i=$week_number_start; $i<=$week_number_end; $i++){
echo '<th style="border: 1px solid black;>Week ' . $i . '</th>';
}
echo '</tr>';
echo '</table>';
}
And where the result is printed out, I get Week 2, Week 4, Week 6 and so on. Pretty much every 2nd week. Why is it doing that? I'm probably missing something very simple..

Answer 1

you have double quote missing in the seconde for loop, as Barmar mentionned, it's combining two elements.
so try this after add the missing double quote:
$retval = f_select_query($query_select_stores, $datarows);
$rowcount = count($datarows);
for ($counter = 0; $counter< $rowcount; $counter++) {
$store_name = $datarows[$counter]->store_name;
echo '<table style="width: 100%; border:1px solid black;">';
echo '<tr>';
echo '<th style="border: 1px solid black;">' . $store_name . '</th>';
for ($i=$week_number_start; $i<=$week_number_end; $i++){
echo '<th style="border: 1px solid black;">Week ' . $i . '</th>';
}
echo '</tr>';
echo '</table>';
}
