1. Write a PHP script that will output the following loop:
$x = "*";
for ($i = 0; $i< 5; $i++){
echo"$x";
echo"<br>";
$x .="* ";
}
2. Write a PHP script that will output the following loop:
for ($i = 0; $i <= 5; $i++){
for($j = 0; $j < $i; $j++){
echo "* ";
}echo"<br>";
}
for ($i = 5; $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["num"])){
$num = $_GET["num"];
$output = 0;
for($i = 1; $i<=$num;$i++){
$output+=$i;
}
echo"$output";
}
4. Write a PHP script that creates the following table (use for loops).
echo "<table class = 'numTable'>";
for($i=1;$i<=10;$i++){
echo "<tr>";
for($j=$i;$j<=$i*10;$j+=$i){
echo"<td><strong>$j</strong></td>";
}echo "</tr><br>";
}echo"</table>";
Output:
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 |
3 | 6 | 9 | 12 | 15 | 18 | 21 | 24 | 27 | 30 |
4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 | 40 |
5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
6 | 12 | 18 | 24 | 30 | 36 | 42 | 48 | 54 | 60 |
7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 | 70 |
8 | 16 | 24 | 32 | 40 | 48 | 56 | 64 | 72 | 80 |
9 | 18 | 27 | 36 | 45 | 54 | 63 | 72 | 81 | 90 |
10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 |
