while Loop:

The while loop is used when you want to execute a block of code as long as a specified condition is true. The show is given follow chat

Syntax:

while (condition) 
{
  // code to be executed
}

Example:

<?php
$x = 1;
while($x <= 10) {
  echo "The number is: $x <br>";
  $x++;
}
?>

do-while Loop:

The do-while loop is similar to the while loop, but the block of code is executed at least once, regardless of whether the condition is true or false.

Syntax:

do {
  // code to be executed
} while (condition);

Example:

<?php
$x =10;
do {
  echo "The number is: $x <br>";
  $x++;
} while ($x <= 9);
?>

for Loop:

The for loop is used when you know exactly how many times you want to execute a block of code. It has a counter variable that is incremented or decremented with each iteration.

Syntax:

for (initialization; condition; increment/decrement) 
{
  // code to be executed
}

Example:

<?php
for ($x = 0; $x <= 10; $x++) {
  echo "The number is: $x <br>";
}
?>

For-each loop:

The foreach loop is used to loop through arrays and objects. It iterates over each element in the array or each property in the object.

Syntax:

foreach ($array as $value) 
{
  // code to be executed
}

Example:

<?php
echo "Welcome to the world of foreach loops <br>";
$arr = array("Bananas", "Apples", "Harpic", "Bread", "Butter");
foreach ($arr as  $value) {
    echo "$value <br>";
}
?>
