PHP Loops: Mastering for, while, do-while, and foreach Loops

The for loop in PHP is used when you know in advance how many times you need to execute a block of code. It is particularly useful for iterating a known number of times, and it offers more control over loop iterations compared to while and do...while loops.

Syntax

for (initialization; condition; increment/decrement) {
    // Code to be executed on each iteration
}

initialization: This expression is executed once at the beginning of the loop. It usually sets a counter variable.
condition: The loop continues to run as long as this condition evaluates to true. It is evaluated before each iteration.
increment/decrement: This expression is executed at the end of each iteration. It is usually used to update the loop counter.

Example

<!DOCTYPE html>

<html>

<body>

<?php

for ($i = 0; $i < 5; $i++) {

echo "The value of i is: $i<br>";

}

</body>

</html>

Try it yourself

Explanation:

The loop starts with $i = 0.
The condition ($i < 5) is evaluated before each iteration. As long as it is true, the code inside the loop is executed.
After each iteration, $i is incremented by 1 using $i++.
The loop stops when $i is no longer less than 5.
