PHP Functions

Function: implode

(PHP 3, PHP 4, PHP 5)

implode -- Join array elements with a string

Description

string implode ( string glue, array pieces )

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

Example 1. implode() example

<?php

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

echo $comma_separated; // lastname,email,phone

?>

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.

Note: As of PHP 4.3.0, the glue parameter of implode() is optional and defaults to the empty string(''). This is not the preferred usage of implode() . We recommend to always use two parameters for compatibility with older versions.

Note: This function is binary-safe.
