PHP中explode()与implode()函数用法
1、explode：使用一个字符串分割另一个字符串
语法：array explode(string $separator,string $string [,int $limit ])
<?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 */
$str = 'one|two|three|four';
// 正数的 limit
print_r(explode('|', $str, 2));
// 负数的 limit（自 PHP 5.1 起）
print_r(explode('|', $str, -1));
/*
* 以上例程会输出：
*
Array
(
[0] => one
[1] => two|three|four
)
Array
(
[0] => one
[1] => two
[2] => three
)
*/ |
2、implode：将数组变成字符串
语法：string implode(string $glue,array $pieces)
<?php
/* 示例 */
$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone |
