1. Write a PHP script that will output the following using a loop.
$j = "* "; for ($i = 0; $i < 5; $i++) { echo $j; $j .= "* "; echo "<br>"; }
2. Write a PHP script that will output the following loop:
for ($i = 1; $i <= 5; $i++) { for ($j = 1; $j <= $i; $j++) { echo "* "; } echo "<br>"; } for ($i = 5 - 1; $i >= 0; $i--) { for ($j = 0; $j <= $i; $j++) { echo "* "; } echo "<br>"; }
3. Create a script using a for loop to add all the integers between 0 and 10 and display the total. The range should be user inputted.
if (isset($_GET['num3'])) { $num3 = $_GET['num3']; $sum = 0; for ($i = 0; $i <= $num3; $i++) { $sum += $i; } echo "Sum between 1 to $num3 is: $sum"; }
4. Write a PHP script that creates the following table (use for loops).
echo "<table border='2'>"; for ($i = 1; $i <= 10; $i++) { echo "<tr>"; for ($j = 1; $j <= 10; $j++) { echo "<td>" . ($i * $j) . "</td>"; } echo "</tr>"; } echo "</table>";
