0 0 1 minute read

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

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

Output:

Welcome to zambiatek A Computer Science Portal

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

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

Output:

{"name":"GFG","0":{"email":"abc@gfg.com","mobile":"XXXXXXXXXX"}}
