Array to String Conversion in PHP

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

                                    // Use json_encode to collapse the array to json string:
$stuff = array(1,2,3);
print json_encode($stuff);   //Prints [1,2,3]

                                    $gadget = array( 'computer', 'mobile', 'tablet' );
echo implode($arr);

                                    function subArraysToString($ar, $sep = ', ') {
    $str = '';
    foreach ($ar as $val) {
        $str .= implode($sep, $val);
        $str .= $sep; // add separator between sub-arrays
    }
    $str = rtrim($str, $sep); // remove last separator
    return $str;
}

// $food array from example above
echo subArraysToString($food);
// apple, raspberry, pear, banana, peas, carrots, cabbage, wheat, rice, oats
