1要替换成apple,2要替换成pear,3要换成banana,4要换成orange。

这样的话,从数据库里读出来是23  。结果是pearbanana。
1234 ===applepearbananaorange。

就是要写一个这样的函数,根据数据查出来的数据换成水果名。

简洁的函数最好,不胜感激


回复讨论(解决方案)

不需要写,php 已经提供了

$d = array( 1 => 'apple', 2 => 'pear', 3 => 'banana', 4 => 'orange');echo strtr('1234',$d);
Copy after login
Copy after login
applepearbananaorange

科学家就是科学家,哎。老徐教教我们该如何学习php吧。

$a = array(1,2,3,4);$b   = array('apple','pear','banana','orange');$output  = str_replace($a, $b, '1234');echo $output;
Copy after login

$str = '1234';echo change($str);function change($str){    $name = array('1'=>'apple', '2'=>'pear', '3'=>'banana', '4'=>'orange');        $tmp = '';    for($i=0,$len=strlen($str); $i<$len; $i++){        $tmp .= $name[substr($str, $i, 1)];    }    return $tmp;}
Copy after login

三种方法都好,不过还是第一种最简洁速度最快

都能用。。试试
