Question

I know this is kinda weird, but I need this to complete my task.

I want to move the first two words to the two words thereafter, example is in my (error) code :

<?
$sentence = "zero one two three four five six seven eight";
$sentence2 = explode (" ",$sentence);
$total = count($sentence2);
for ($i = 4; $i < $total; ++$i) {
$result = $sentence2[2]." ".$sentence2[3]." ".$sentence2[0]." ".$sentence2[1]."  ".$sentence2[$i];
}
echo "Original sentence : ".$sentence;
echo "<br>Result : ".$result;
?>

but the result from that code is not what i want, the result is

two three zero one eight

i want the result :

two three zero one four five six seven eight

can you help me make a better code?

Answer 1

Each time the code inside your loop runs, the $result variable receives a new value.

You should only append words at the end of the sequence to it.

So, replace you for loop by this:

$result = $sentence2[2]." ".$sentence2[3]." ".$sentence2[0]." ".$sentence2[1];
for ($i = 4; $i < $total; ++$i) {
    $result .= "  ".$sentence2[$i];
}
