How to create a string by joining the array elements using PHP ?

  • Last Updated : 01 Jun, 2020

We have given an array containing some array elements and the task is to join all the array elements to make a string. In order to do this task, we have the following methods in PHP:

Method 1: Using implode() Method: The implode() method is used to join an array of elements that are separated by a string. Joining can be done with or without separator.

Syntax:

string implode($separator, $array)

Example :

PHP




<?php
// PHP program to create a string by 
// joining the values of an array
  
// Function to get the string 
function get_string ($arr) {
      
    // Using implode() function to
    // join without separator 
    echo implode($arr); 
        
    // Using implode() function to
    // join with separator 
    echo implode("-", $arr); 
}
  
// Given array
$arr = array('Geeks','for','Geeks',"\n");
  
// function calling
$str = get_string ($arr); 
?>
Output



GeeksforGeeks
Geeks-for-Geeks-

Method 2: Using join() Method: The join() method is used to join an array of elements that are separated by a string. Joining can be done with or without separator. The join() method is same as the implode() method.

Syntax:

string join($separator, $array)

Example :

PHP




<?php
// PHP program to create a string by 
// joining the values of an array
  
// Function to get the string 
function get_string ($arr){
      
    // Using join() function to
    // join without separator 
    echo join($arr); 
        
    // Using join() function to
    // Join with separator 
    echo join("-", $arr); 
}
  
// Given array
$arr = array('Geeks','for','Geeks',"\n");
  
// function calling
$str = get_string ($arr); 
?>
Output
GeeksforGeeks
Geeks-for-Geeks-
