In this article, you will learn about how to convert the array into a string in PHP. The join() function converts the array into a string or in other words, it returns a string by joining the elements of the array.
Join() function is an alias of the implode() function. Also, it accepts the parameters in both lefts to right/right to left order. However, they are passed in the order of convention (like explode() function).
You can also specify the separator character but it is not mandatory. However, for backward compatibility, you must use the two arguments.

echo join(" ",$arr);

<?php
$arr = array('Hello','PHP!','Sunny','Day!');
echo join(/ ",$arr)."<br>";
echo join("AB",$arr)."<br>";
echo join("-",$arr)."<br>";
