PHP Iterative Statements

Iterative statements are used to run same block of code over and over again for a certain number of times.

In PHP, we have the following loops:

while Loop
do-while Loop
for Loop
foreach loop

1. While Loop

The While loop in PHP is used when we need to execute a block of code again and again based on a given condition. If the condition never becomes false, the while loop keeps getting executed. Such a loop is known as an infinite loop.

Example:

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

2. Do-While Loop

The do-while loop is similar to a while loop except that it is guaranteed to execute at least once. After executing a part of a program for once, the rest of the code gets executed based on a given boolean condition.

Example:

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

3. For Loop

The for loop is used to iterate a block of code multiple times.

Example:

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

4. Foreach loop

The foreach loop in PHP can be used to access the array indexes in PHP. It only works on arrays and objects.

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>";
}
?>
