微调器问题-PHP foreach [英] Spinner problem - PHP foreach

问题描述

我在对找到的脚本进行编排时遇到问题.

I have a problem costomizing a script i found.

该脚本如下所示:

function spin($var){
$words = explode("{",$var);
foreach ($words as $word)
{
    $words = explode("}",$word);
    foreach ($words as $word)
    {
        $words = explode("|",$word);
        $word = $words[array_rand($words, 1)];        
        echo $word." ";

    }

}
}

$text = "Digitalpoint.com is {the best forum|a great Forum|a wonderful Forum|a perfect Forum} {123|some other sting}";
spin($text);

我想自定义脚本以返回结果的值.

I'd like to customize the script to return the value of the result.

示例:

$spin = spin($text);
echo $spin;

我试图通过生成一个结果变量

I've tried to generate a result variable by

$output = $output + $word." ";
return $output;

然后

$spin = spin($text);
echo $spin;

但是我总是得到结果"0" ...有人可以为这个问题提出一个聪明的解决方案吗?我期待任何提示/提示，谢谢！！

But i've always got result "0"... Can anyone come up with a clever solution for this problem? I'm looking forward to any tips/hints, thanks in advance!

推荐答案

尝试一下. spun函数未返回值.代替使用echo，我们将结果附加到字符串$spun上并返回.

Try this. The spun function wasn't returning a value. Instead of using echo, we'll just append the results onto string $spun and return that.

function spin($var){
$spun = "";

$words = explode("{",$var);
foreach ($words as $word)
{
    $words = explode("}",$word);
    foreach ($words as $word)
    {
        $words = explode("|",$word);
        $word = $words[array_rand($words, 1)];        
        $spun .= $word." ";
    }
}

return $spun;
}
