implode

(PHP 4, PHP 5)

implode — Join array elements with a string

说明

string implode ( string $glue , array $pieces )

string implode ( array $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.

参数

glue

Defaults to an empty string.

pieces

The array of strings to implode.

返回值

Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.

更新日志

版本	说明
4.3.0	The `glue` parameter became optional.

范例

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) ""

?>
