for循环中的随机数组PHP

Question

Currently working on a.. lets say random word generator. I think I made it already work, but unfortunately for loop returns the same value as the first one.

`

$ones = array("One.", "Two.", "Three.", "Four.", "Five.", "Six.", "Seven.", "Eight.", "Nine.", "Ten.");
$one_rand = array_rand($ones, 2);
$one = $ones[$one_rand[0]];

$twos = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10");
$two_rand = array_rand($twos, 2);
$two = $twos[$two_rand[0]];

$ends = array(".a", ".b", ".c", ".d", ".e", ".g", ".h", ".i", ".j");
$end_rand = array_rand($ends, 2);
$end = $ends[$end_rand[0]];



$return = $one . $two . $end;



for ($x = 1; $x <= 5; $x++) {
    echo $return . "<br>";
}

`

This code returns(for example):

Three.4.b
Three.4.b
Three.4.b
Three.4.b
Three.4.b

But I want it to be random after every " < br > ".

Thank you in advance.

so the issue is that you assign the values to $one, $two, $three once, that means it will not change when you create a loop after that, what you need to do is loop the value assignment something like:

$ones = array("One.", "Two.", "Three.", "Four.", "Five.", "Six.", "Seven.", "Eight.", "Nine.", "Ten.");
$twos = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10");
$ends = array(".a", ".b", ".c", ".d", ".e", ".g", ".h", ".i", ".j");

for ($x = 1; $x <= 5; $x++) {
    $one_rand = array_rand($ones, 2);
    $one = $ones[$one_rand[0]];
    $two_rand = array_rand($twos, 2);
    $two = $twos[$two_rand[0]];
    $end_rand = array_rand($ends, 2);
    $end = $ends[$end_rand[0]];
    $return = $one . $two . $end;

    echo $return . "<br>";
}

But that means you will need to call array_rand for each loop, which is pretty bad, a better choice would be to just randomize the array first and then you can use the loop index to choose the values, which will still be random but faster, something like:

$ones = array("One.", "Two.", "Three.", "Four.", "Five.", "Six.", "Seven.", "Eight.", "Nine.", "Ten.");
$twos = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10");
$ends = array(".a", ".b", ".c", ".d", ".e", ".g", ".h", ".i", ".j");
// I have used shuffle instead of array_rand, because for array_rand you 
// need to specify the number of items returned, which is not really dynamic
shuffle($ones);
shuffle($twos);
shuffle($ends);

for ($x = 1; $x <= 5; $x++) {
    echo $ones[$x] . $two[$x] . $end[$x] . "<br>";
}
