[FIXED] How can I move chinese characters in a string to the end of string?

Issue

I have a string like this now: I want to do the following in PHP:

$string = 'Testing giving dancing 喝 喝 passing 制图 giving 跑步 吃';

I want to move all Chinese characters to the end of the string, and also reversing their current order. Accordingly, Removing the duplicate English words and Return the modified string

Solution

Here you go! Check the comments in the code:

<?php

$string = 'Testing giving dancing 喝 喝 passing 制图 giving 跑步 吃';

// split by a space into an array
$explosion = explode(' ', $string);

$normalWords = [];
$chineseWords = [];

// loop through the array
foreach ($explosion as $debris) {

   // if not normal alphabet characters
   if (!preg_match('#[a-zA-Z]+#', $debris) && !in_array($debris, $chineseWords)) {
       // add to chinese words array if not already in the array
      $chineseWords[] = $debris;
   } elseif (preg_match('#[a-zA-Z]+#', $debris) && !in_array($debris, $normalWords)) {
        // add to normal words array if not already in the array
       $normalWords[] = $debris;
   }
}

// reverse the chinese characters like you wanted
$chineseWords = array_reverse($chineseWords);

// Piece it all back together
$string = implode(' ', $normalWords) . ' ' . implode(' ', $chineseWords);

// and output
echo $string;  // Testing giving dancing passing 吃 跑步 制图 喝
