What are the differences between using a for loop and a while loop in PHP?

When choosing between a for loop and a while loop in PHP, the main difference lies in the syntax and the way they control the loop. A for loop is typically used when you know the exact number of iterations needed, while a while loop is more flexible and can be used when the number of iterations is not known in advance. Additionally, a for loop includes the initialization, condition, and increment/decrement all in one line, while a while loop requires these to be handled separately within the loop. 

// Using a for loop to iterate a specific number of times
for ($i = 0; $i < 5; $i++) {
    echo "Iteration: $i <br>";
}

// Using a while loop to iterate until a condition is met
$j = 0;
while ($j < 5) {
    echo "Iteration: $j <br>";
    $j++;
}
