PHP Manual: Join array elements with a string

Description

string implode ( string $glue , array $pieces )

string implode ( array $pieces )

Join array elements with a glue string.

Note:
implode can, for historical reasons, accept its parameters in either order. For consistency with explode, however, it may be less confusing to use the documented order of arguments.

Parameters

glue: Defaults to an empty string.
pieces: The array of strings to implode.

Return Values

Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.

Changelog

Version	Description
4.3.0	The `glue` parameter became optional.

Examples

Example #1 implode example


<?php

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

echo $comma_separated; // lastname,email,phone

// Empty string when using an empty array:
var_dump(implode('hello', array())); // string(0) ""

?>
