How to convert array to string in PHP ?

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", "GeeksforGeeks",
    "A", "Computer","Science","Portal");

// Converting array elements into
// strings using implode function
echo implode(" ",$arr);

?>

Output:

Welcome to GeeksforGeeks 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"}}
