Replacing substrings of nested arrays with a value from another array-CodePudding

The loop below outputs from the $defaultValues values, there are 2 nested arrays in this array which are "colors" and "lessons".

This loop also takes the substring values from the $search array and replaces them with the values from the $replace.

Question: How to replace nested array clause value "colors" and "lessons" from $defaultValues

values: "colors"=>["4", "5", "6"] and "lessons" =>["7 " , " 8", "9"] from $replace"

I can't figure out how to do this, my current code outputs this:

Name: 1
Age: 2
Whe are u from: 3
Your favorite color: 4
Choose courses: 7
Your comment: 10

I would like the code to output this:

Name: 1
Age: 2
Whe are u from: 3
Your favorite color: 4,5,6
Choose courses: 7,8,9
Your comment: 10

$defaultValues = [
  "name"     =>  "Name:                   <div class='user'>     write your name                     </div>", 
  "age"      =>  "Age:                    <div class='age'>      enter your age                      </div>",
  "from"     =>  "Whe are u from:         <div class='from'>     write where are you from            </div>", 
  "colors"   =>  ["Your favorite color:   <div class='colors'>   you didn't say your favorite color  </div>"],        
  "lessons"  =>  ["Choose courses:        <div class='lessons'>  you have not chosen any course      </div>"],
  "comment"  =>  "Your comment:           <div class='comment'>  no comments                         </div>",     
];
 
$search = [
  "name"     =>  "write your name", 
  "age"      =>  "enter your age", 
  "from"     =>  "write where are you from", 
  "colors"   =>  ["you didn't say your favorite color"],        
  "lessons"  =>  ["you have not chosen any course"],
  "comment"  =>  "no comments",   
];
 
$replace = [
  "name"     =>  "1", 
  "age"      =>  "2",
  "from"     =>  "3",
  "colors"   =>  ["4", "5", "6"],        
  "lessons"  =>  ["7", "8", "9"],
  "comment"  =>  "10",       
];
 
 
foreach($defaultValues as $key => $items){
  echo "<div class='block'>";
 
  if(is_array($items)){
    foreach($items as $child){
        $items = str_replace($search[$key], $replace[$key], $child);
    }
  }
 
  echo $items = str_replace($search[$key], $replace[$key], $items);   
 
  echo "</div>";  
}

If you meant to join the array of colors and lessons to create the string to replace the corresponding placeholders you may use the function implode

https://www.php.net/manual/en/function.implode.php

Here's the code fragment:

if(is_array($items)){
  foreach($items as $child){
    $replaceListImploded = implode(",", $replace[$key]);
    $items = str_replace($search[$key], $replaceListImploded, $child);
  }
}

The corresponding output:

<div class='block'>
  Your favorite color:   <div class='colors'>   4,5,6  </div>
</div>
<div class='block'>
  Choose courses:        <div class='lessons'>  7,8,9      </div>
</div>

You just need to use implode to parse the array into a comma-separated string for output!

// example code

$defaultValues = [
    "name"     =>  "Name:                   <div class='user'>     write your name                     </div>", 
    "age"      =>  "Age:                    <div class='age'>      enter your age                      </div>",

echo $items = is_array($search[$key]) ? implode(',', $replace[$key]) : str_replace($search[$key], $replace[$key], $items);
