(PHP 4, PHP 5)
implode — Join array elements with a string
$glue
, array $pieces
)$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.
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.
Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.
| Version | Description |
|---|---|
| 4.3.0 |
The glue parameter became optional.

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) ""
?>
