We have given an array and the task is to convert the array elements into a string. In this query, we are using two methods to convert an array to a string.

Method 1: Using implode() function: The implode() method is an inbuilt function in PHP and is used to join the elements of an array. The implode() method is an alias for PHP | join() function and works exactly same as that of join() function.

Syntax:

string implode($separator, $array)
Example:

<?php  
  
// Declare an array 
$arr = array("Welcome","to", "DevopforDevops", 
    "A", "Computer","Language","program");  
    
// Converting array elements into
// strings using implode function
echo implode(" ",$arr);
   
?>

Output:

Welcome to DevopsforDevops A Computer Language Program
Method 2: Using json_encode() Function: The json_encode() function is an inbuilt function in PHP which is used to convert PHP array or object into JSON representation.
Syntax:

string json_encode( $value, $option, $depth )
Example:

<?php 
  
// Declare multi-dimensional array 
$value = array( 
    "name"=>"DFD", 
    array( 
        "email"=>"dce@dfd.com", 
        "mobile"=>"XXXXXXXXXX"
    ) 
); 
  
// Use json_encode() function 
$json = json_encode($value); 
  
// Display the output 
echo($json); 
  
?> 
Output:

{"name":"DFD","0":{"email":"dce@dfd.com","mobile":"XXXXXXXXXX"}}
