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.
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.
| 版本 | 说明 |
|---|---|
| 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) ""
?>
Note: 此函数可安全用于二进制对象。
