The implode Function

The implode function merges an array into a string with a specified separator.

Syntax

implode(string $separator, array $array): string

Let's merge an array into a string:

<?php
	$arr = ['a', 'b', 'c', 'd', 'e'];
	echo implode('-', $arr);
?>

Code execution result:

'a-b-c-d-e'

Using an empty separator:

<?php
	$arr = ['a', 'b', 'c', 'd', 'e'];
	echo implode('', $arr);
?>

Code execution result:

'abcde'
