WeberDev.com -> 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. This is not the preferred usage of implode() as glue would be the second parameter and thus, the bad prototype would be used.
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

?>

Notes

Note: This function is binary-safe.
