Combine array elements into a string:
<?php$arr = array('Hello','World!','Beautiful','Day!');echo implode(" ",$arr);?>The implode() function returns a string composed of array elements.
Note: The implode() function accepts two parameter orders. However, due to historical reasons, explode() does not work. You must ensure that the separator parameter comes before the string parameter.
Note: The separator parameter of the implode() function is optional. However, for backward compatibility, it is recommended that you use two parameters.
Note: This function is binary safe.
