(PHP 4, PHP 5, PHP 7)
implode — Join array elements with a string
implode ( string $glue , array $pieces ) : string
implode ( array $pieces ) : string
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 is deprecated not to use the documented order of arguments.
glue
Defaults to an empty string.
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 |
|---|---|
| 7.4.0 | Passing the glue after the pieces (i.e. not using the documented order of parameters) has been deprecated. |
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) ""
?> Note: This function is binary-safe.
