Until in PHP

In PHP, the until loop is not a standard looping construct. However, you can use a do-while loop with a negated condition to achieve the same effect as an until loop. Here's an example:

$i = 0;
do {
    echo $i . "\n";
    $i++;
} while ($i < 10);

This code will output the numbers 0 to 9. Alternatively, you can use a traditional while loop with a negated condition to achieve the same effect:

$i = 0;
while (!($i >= 10)) {
    echo $i . "\n";
    $i++;
}

Both of these examples will effectively loop until the condition is false, which achieves the same effect as an until loop.
