$arr = array("This","is", "an", "array");  
$string = implode(" ",$arr);  
echo "The array is converted to the string.";
echo "\n";
echo "The string is '$string'";
?>

   $JsonObject = json_encode($array);
   echo "The array is converted to the JSON string.";
   echo "\n"; 
   echo"The JSON string is $JsonObject";
?>

The array is converted to the JSON string.
The JSON string is ["Lili","Rose","Jasmine","Daisy"]

<?php
   $array = ["Lili", "Rose", "Jasmine", "Daisy"];
   $JsonObject = serialize($array);
   echo "The array is converted to the JSON string.";

   echo"The JSON string is $JsonObject";
