implode

(PHP 3, PHP 4, PHP 5)

implode -- Join array elements with a string

Description

string implode ( string glue, 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. This is not the preferred usage of implode() as glue would be the second parameter and thus, the bad prototype would be used.
pieces

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

?>

Notes

Note: This function is binary-safe.
