Chess is a recreational and competitive board game played between two players. It is played on a square chessboard with 64 squares arranged in an eight-by-eight grid black-white alternatively. In this article, we will learn how to design a Chess Board using PHP.
Approach:
- To create Chess in php; we have to run 2 loops each will create 8 blocks.
- The inner-loop will generate table-row with black/white background-color based upon a value .
- If value is even, Black background is generated .
- If value is odd, White background is generated
Chess Board using For-Loop:
PHP
<!DOCTYPE html> <html> <body> <table width="400px" border="1px" cellspacing="0px">
<?php
echo "Chess by GeeksforGeeks";
$value = 0;
for($col = 0; $col < 8; $col++) {
echo "<tr>";
$value = $col;
for($row = 0; $row < 8; $row++) {
if($value%2 == 0) {
echo "<td height=40px width=20px bgcolor=black></td>";
$value++;
}
else {
echo "<td height=40px width=20px bgcolor=white></td>";
$value++;
}
}
echo "</tr>";
}
?>
</table>
</body> </html> |
Chess Board using while-Loop:
PHP
<!DOCTYPE html> <html> <body> <table width="400px" border="1px" cellspacing="0px">
<?php
echo "Chess by GeeksforGeeks";
$value = 0;
$col = 0;
while($col < 8) {
$row = 0;
echo "<tr>";
$value = $col;
while($row < 8) {
if($value%2 == 0) {
echo "<td height=40px width=20px bgcolor=black></td>";
$value++;
}
else {
echo "<td height=40px width=20px bgcolor=white></td>";
$value++;
}
$row++;
}
echo "</tr>";
$col++;
}
?>
</table>
</body> </html> |
Chess Board using do-while loop:
PHP
<!DOCTYPE html> <html> <body> <table width="400px" border="1px" cellspacing="0px">
<?php
echo "Chess by GeeksforGeeks";
$value = 0;
$col = 0;
do {
$row = 0;
echo "<tr>";
$value = $col;
do {
if($value%2 == 0) {
echo "<td height=40px width=20px bgcolor=black></td>";
$value++;
}
else {
echo "<td height=40px width=20px bgcolor=white></td>";
$value++;
}
$row++;
}while($row < 8);
echo "</tr>";
$col++;
}while($col < 8);
?>
</table>
</body> </html> |
Output: All the code will give the same output.
