How to implement a foreach inside a for loop in PHP?

April 7, 2022

I’m new to PHP & Stackoverflow. Correct my questions if I make a mistake here.
My goal to accomplish here is to get a random color (for loop) followed by the sequence (foreach) accordingly. Here is my code below.

  $color = array("green", "red", "yellow");
  $sequence = array("R", "B", "B");

  for ($x = 1; $x <= 10; $x++) {
    $color_random = $color[array_rand($color)];
    echo $color_random . "- ";
  }

  foreach ($sequence as $sequence_value) {
    echo $sequence_value . "- ";
  }

Currently the results is "yellow- green- yellow- red- green- green- red- green- yellow- green- R- B- B-"
.

How can I convert it/change it to yellow-R- green-B- yellow-B- red-R- green-B- green-B- red-R- green-B- yellow-B- green-R- (random color – sequence -) As you can see, 10 random colors generated, but the sequence follows according.

Any answers or comments would be great as this is learning progress for me and others as well. Thank you.

>Solution :

You can try this:

$color = array("green", "red", "yellow");
$sequence = array("R", "B", "B");

for ($x = 1; $x <= 10; $x++) {
foreach ($sequence as $sequence_value) {
    $color_random = $color[array_rand($color)];
    echo $color_random . "- " . $sequence_value . "- ";
}
}
