How to display array values with do while or for statement in my PHP?

In PHP, you can display array values using loop structures like do-while and for statements. These loops provide different approaches to iterate through array elements and display them.

Syntax

The basic syntax for a do-while loop is −

do {
    // statements
} while (condition);

The basic syntax for a for loop is −

for (initialization; condition; increment) {
    // statements
}

Using do-while Loop

The do-while loop executes the code block at least once before checking the condition ?

<?php
    $values = array('John', 'David', 'Mike', 'Sam', 'Carol');
    $i = 0;
    $len = count($values);
    
    do {
        echo $values[$i] . " ";
        $i++;
    } while ($i < $len);
?>

Using for Loop

The for loop is more concise and commonly used for array iteration ?

<?php
    $values = array('John', 'David', 'Mike', 'Sam', 'Carol');
    $len = count($values);
    
    for ($i = 0; $i < $len; $i++) {
        echo $values[$i] . " ";
    }
?>

Conclusion

Both do-while and for loops can effectively display array values in PHP. The for loop is generally preferred for array iteration due to its concise syntax, while do-while is useful when you need guaranteed execution.
