Iterate in PHP

In PHP, we can iterate over an array using various loops, namely for, foreach, while and do-while. Here are some examples:

1. Using the for loop:

$fruits = array('apple', 'banana', 'cherry', 'orange', 'grape');

$len = count($fruits);

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

    echo $fruits[$i] . "
";

}

2. Using the foreach loop:

$fruits = array('apple', 'banana', 'cherry', 'orange', 'grape');

foreach ($fruits as $fruit) {

    echo $fruit . "
";

}

3. Using the while loop:

$fruits = array('apple', 'banana', 'cherry', 'orange', 'grape');

$len = count($fruits);

$i = 0;

while ($i < $len) {

    echo $fruits[$i] . "
";

    $i++;

}

4. Using the do-while loop:

$fruits = array('apple', 'banana', 'cherry', 'orange', 'grape');

$len = count($fruits);

$i = 0;

do {

    echo $fruits[$i] . "
";

    $i++;

} while ($i < $len);

All the above examples will output the same result, which is a list of fruits on separate lines (assuming "
" is properly interpreted).
