php将数组转换成字符串例子
1.implode将数组元素组合为字符串
连接符为 ^ 的例子：
- <?php
- $array = array('姓名', '电话', '电子邮箱');
- $char = implode("^", $array);
- echo $char;
- ?>
浏览器输出：
姓名^电话^电子邮箱
可以使用空格作为连接符：
- <?php
- $char = implode(" ", $array);
- ?>
2.自定义函数
- function array2string($data, $isformdata = 1) {
- if($data == '') return '';
- //if($isformdata) $data = stripslashes($data);
- return addslashes(var_export($data, TRUE));
- }
字符转换成数组
例子 1. explode() 示例
- <?php
- // 示例 1
- $pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
- $pieces = explode(" ", $pizza);
- echo $pieces[0]; // piece1
- echo $pieces[1]; // piece2
- // 示例 2
- $data = "foo:*:1023:1000::/home/foo:/bin/sh";
- list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
- echo $user; // foo
- echo $pass; // *
- ?>
例子 2. limit 参数示例
- <?php
- $str = 'one|two|three|four';
- // 正数的 limit
- print_r(explode('|', $str, 2));
- // 负数的 limit
- print_r(explode('|', $str, -1));
- ?>
以上示例将输出:
- Array
- (
- [0] => one
- [1] => two|three|four
- )
- Array
- (
- [0] => one
- [1] => two
- [2] => three
- )
