implode (PHP 3, PHP 4 )implode -- Join array elements with a string Description string implode ( string glue, array pieces) Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element. 例子 1. implode() example<?php$array = array('lastname', 'email', 'phone'); $comma_separated = implode(",", $array);echo $comma_separated; // lastname,email,phone?>
注: 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. 注: As of PHP 4.3.0, the glue parameter of implode() is optional and defaults to the empty string(''). This is not the preferred usage of implode(). We recommend to always use two parameters for compatibility with older versions. explode (PHP 3, PHP 4 )explode -- Split a string by string Description array explode ( string separator, string string [, int limit]) Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string separator. If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string. If separator is an empty string (""), explode() will return FALSE. If separator contains a value that is not contained in string, then explode() will return an array containing string. Although implode() can, for historical reasons, accept its parameters in either order, explode() cannot. You must ensure that the separator argument comes before the string argument. 注: The limit parameter was added in PHP 4.0.1 例子 1. explode() examples<?php // Example 1 $pizza = "piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = explode(" ", $pizza); echo $pieces[0]; // piece1 echo $pieces[1]; // piece2// Example 2 $data = "foo:*:1023:1000::/home/foo:/bin/sh"; list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data); echo $user; // foo echo $pass; // *?>
