Part 1 – For Loop
- For Loop – To Repeat no of Times.
- Syntax:
<?php
for($i = 1; $i <= 5; $i++){
echo "Number: $i <br>";
}
?>
Part 2 – While Loop
- While Loop condition true இருக்கும் வரை repeat செய்யும்.
<?php
$i = 1;
while($i <= 5){
echo "Number: $i <br>";
$i++;
}
?>
Part 3 – Do-While Loop
- Do-While Loop குறைந்தது ஒரு முறை code execute செய்யும்.
<?php
$i = 1;
do{
echo "Number: $i <br>";
$i++;
} while($i <= 5);
?>
Part 4 – Foreach Loop
- Foreach Loop mainly arrays iterate செய்ய பயன்படும்.
<?php
$colors = array("Red","Green","Blue");
foreach($colors as $color){
echo "Color: $color <br>";
}
?>
Part 5 – Real-life Example

- Table rows iterate
- Invoice items repeat
<?php
$items = array("Pen"=>10,"Book"=>5,"Notebook"=>7);
foreach($items as $item => $qty){
echo "$item quantity: $qty <br>";
}
?>
