Php Nested loop example

 for ($i = 1; $i <= 3; $i++) {

echo "Outer loop iteration: $i <br>"; for ($j = 1; $j <= 3; $j++) { echo "Inner loop iteration: $j <br>"; } }

In this example, we have an outer loop that iterates three times, and within each iteration of the outer loop, we have an inner loop that also iterates three times.

The output of this code will be:

Outer loop iteration: 1 Inner loop iteration: 1 Inner loop iteration: 2 Inner loop iteration: 3 Outer loop iteration: 2 Inner loop iteration: 1 Inner loop iteration: 2 Inner loop iteration: 3 Outer loop iteration: 3 Inner loop iteration: 1 Inner loop iteration: 2 Inner loop iteration: 3

3 step inner loop:-

for ($i = 1; $i <= 3; $i++) { echo "Outer loop iteration: $i <br>"; for ($j = 1; $j <= 3; $j++) { echo "Inner loop iteration: $j <br>"; for ($k = 1; $k <= 3; $k++) { echo "Innermost loop iteration: $k <br>"; } } }

In this example, we have an outer loop that iterates three times, and within each iteration of the outer loop, we have an inner loop that also iterates three times. Additionally, within each iteration of the inner loop, we have an innermost loop that iterates three times.

The output of this code will be:

Outer loop iteration: 1 Inner loop iteration: 1 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 2 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 3 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Outer loop iteration: 2 Inner loop iteration: 1 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 2 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 3 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Outer loop iteration: 3 Inner loop iteration: 1 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 2 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3 Inner loop iteration: 3 Innermost loop iteration: 1 Innermost loop iteration: 2 Innermost loop iteration: 3
