(PHP 4, PHP 5)
implode — Join array elements with a 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 may be less confusing to use the documented order of arguments.
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.
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
?>
Note: This function is binary-safe.
