The join() function in PHP is used to join the elements of an array into a string. It is also known as the implode() function.


Here is the syntax of the join() function:

join(separator, array)

The first argument is the separator that will be used to join the elements of the array. The second argument is the array to be joined.


Here is an example of how to use join():


$fruits = ["apple", "banana", "orange"];
$fruit_string = join(", ", $fruits);
echo $fruit_string;

This will output:

apple, banana, orange

In this example, the join() function has joined the elements of the $fruits array into a string using the separator ", ". The resulting string is stored in the $fruit_string variable and is then printed to the screen using the echo statement.
