Loops — PHP Tutorial

For, While, and Foreach

PHP supports for, while, do-while, and the powerful foreach loop for arrays.

Example

<?php
// For loop
for ($i = 0; $i < 5; $i++) {
    echo "$i ";
}

// While loop
$count = 0;
while ($count < 5) {
    echo "$count ";
    $count++;
}

// Foreach — iterate over arrays
$fruits = ["Apple", "Banana", "Cherry"];
foreach ($fruits as $fruit) {
    echo "$fruit ";
}

// Foreach with key => value
$ages = ["Alice" => 25, "Bob" => 30];
foreach ($ages as $name => $age) {
    echo "$name is $age years old\n";
}

// Break and continue
for ($i = 0; $i < 10; $i++) {
    if ($i === 5) break;
    if ($i % 2 === 0) continue;
    echo "$i "; // 1 3
}
?>
