<?php
echo '<table width="800" border="1">';
for ($i = 0; $i < 100; $i ) {
if($i ==0){
if($i ==0){
echo '<tr>';
}else{
echo '<tr bgcolor "red">';
I can't understand why $i needs to be incremented by 1. When trying to remove increment if($i ==0), the list will lose its original order, but this is not the case at the end of </tr> in the while loop. In the case of adding 1, the strange thing is that 1 was not added at the end of the while loop. After adding 1, the original order of the list is also lost.
if(($i 1) ==0){
echo '</tr>';

}
echo '</table>';
?>
