implode in php

The implode() function returns a string from the elements of an array.

Note: The implode() function accept its parameters in either order. However, for consistency with explode(), you should use the documented order of arguments.

Note: The separator parameter of implode() is optional. However, it is recommended to always use two parameters for backwards compatibility.

Note: This function is binary-safe.

$arr = array('Hello','World!','Beautiful','Day!');
echo implode(" ",$arr);
