The foreach loop in PHP. Syntax and array iteration. Code example

Special loop for sorting arrays

Example:

$users = [1 => "Billy", 2 => "Max", 3 => "Brianna", 5 => "Stiven"];

foreach($users as $user)//specify which array to iterate and a variable to which one element of the array will be passed
{
    echo "$user";
}

The foreach loop allows you to extract not only values, but also element keys:

$users = [1 => "Billy", 2 => "Max", 3 => "Brianna", 5 => "Stiven"];
foreach($users as $key => $value)
{
    echo "$key - $value";
}
?>
