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
7.4.0 Passing the glue after the pieces (i.e. not using the documented order of parameters) has been deprecated.

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) ""

?>
