有人可以帮我修复重复数字的匹配数量吗？

Question

I have a script that creates two sets of numbers: 1. a list of random numbers 2. a list of match numbers of repeating numbers

But the list of match numbers of repeating numbers is not working properly.

Let me give an example: Random numbers 5-14-5-4-15-12-8-10-18-13-11-25-15-14-2-7-24-22-13-22-16-18-10-11-25-2-18-9-19-8-1-16-1-23-0-16-17-23-21-20-22-21-9-4-20-24-19-16-9-17

Match numbers 3-11-2-6-2-3-2-2-2-2-2-4-3-2-4-3-4-2-2-2-2-2-2-2-2-2

If you look at the random numbers you see the first match number is the correct. After three numbers we have a match so that match number is 3. Then we start counting from the 5 and the next match number is also correct which is 11 and ends at number 15. But then we should have a match after 2 numbers but this does not work out properly.

Can someone assist me here?

<?php
$existing = [];
$repeat_numbers = [];

for ($rnd=1;$rnd<=50;$rnd++)
{
$randoms[] = mt_rand(0,25);
}
echo implode('-',$randoms).PHP_EOL;

echo "<br><br>";

$i = 1;
 foreach($randoms as $rnd){
 if(in_array($rnd,$existing)){
     $repeat_numbers[] = $i;
     $i=1;
 }
 $existing[] = $rnd;
 $i++;
 }
echo implode('-',$repeat_numbers);
?>

As per your expected match, "The match numbers should be: 3-11-8-8-7-6-8"

<?php
$existing = [];
$repeat_numbers = [];
$randoms = explode('-','5-14-5-4-15-12-8-10-18-13-11-25-15-14-2-7-24-22-13-22-16-18-10-11-25-2-18-9-19-8-1-16-1-23-0-16-17-23-21-20-22-21-9-4-20-24-19-16-9-17');
//print_r($randoms);
$i = 0;
foreach($randoms as $rnd){
   $i++; 
   if(in_array($rnd,$existing)){
       $repeat_numbers[] = $i;
       $i=1;
       $existing = [];
   }
   $existing[] = $rnd; 
}
echo implode('-',$repeat_numbers);
?>

Then just add this instead of hard coded $random string variable and use the rest of the code as usual.

<?php
$existing = [];
$repeat_numbers = [];
for ($rnd=1;$rnd<=50;$rnd++)
{
  $randoms[] = mt_rand(0,25);  // see this block for generating randoms
}
$i = 0;
foreach($randoms as $rnd){
   $i++; 
   if(in_array($rnd,$existing)){
       $repeat_numbers[] = $i;
       $i=1;
       $existing = [];
   }
   $existing[] = $rnd; 
}
echo implode('-',$repeat_numbers);
?>
