Question

我有一个带有内爆的array_rand输出问题，我已经停留了2天。任何帮助都会很感激。

function shuffle_assoc($list) { 
    if (!is_array($list)) return $list; 

    $keys = array_keys($list); 
    shuffle($keys); 
    $random = array(); 
    foreach ($keys as $key) { 
        $random[$key] = $list[$key]; 
    }
    return $random; 
} 

$keywords_array = array("car 1 "," car 2 "," car 3 "," car 4 "," car 5 "," car 5 "," car 6");
$frontword_list = array("Amazing", "Good-Looking", "Magnificent", "Pretty", "Sparkling", "Awesome", "Imaginative", "Outstanding");
$frontword_list = $frontword_list[array_rand($frontword_list)];
$preposition = array(" alongside "," amidst "," among ", " beside "," including ","  near ", " as well "," next to ", " within ");
$preposition_rand = $preposition[array_rand($preposition)];
$description = $frontword_list ." ". implode($preposition_rand, shuffle_assoc($keywords_array));
echo $description;

$preposition_rand的输出不会随机播放

Amazing car 2 next to car 6 next to car 5 next to car 3 next to car 5 next to car 1 next to car 4

将$preposition_rand输出改为

的正确代码是什么？

Amazing car 2 amidst car 6 including car 5 alongside car 3 beside car 5 near car 1 as well car 4

Answer 1

你可以试试这个：

<?php

function shuffle_assoc($list) { 
  if (!is_array($list)) return $list; 

  $keys = array_keys($list); 
  shuffle($keys); 
  $random = array(); 
  foreach ($keys as $key) { 
    $random[$key] = $list[$key]; 
  }
  return $random; 
}

//a new function that returns the string according to the requirements
function implode_array($prep,$keywords_arr) {
    $string = "";
    for ( $num = 0; $num < count($keywords_arr); $num++ ) {
        $random_index = rand(0,count($prep)-1); //set random number, random number does not exceed the length of $preposition
        if ( $num != count($keywords_arr)-1 ) {
            $string .= $keywords_arr[$num] . $prep[$random_index]; //insert preposition after keywords_array[$num] if keyword isn't last of array
        } else {
            $string .= $keywords_arr[$num]; //does not insert preposition after the last index in keywords_array
        }
        unset($prep[$random_index]); //unset used index
        $prep = array_values($prep); //reset index values
    }
    return $string;
}

$keywords_array = array("car 1 "," car 2 "," car 3 "," car 4 "," car 5 "," car 5 "," car 6");
$frontword_list = array("Amazing", "Good-Looking", "Magnificent", "Pretty", "Sparkling", "Awesome", "Imaginative", "Outstanding");
                    $frontword_list = $frontword_list[array_rand($frontword_list)];
                    $preposition = array(" alongside "," amidst "," among ", " beside "," including ","  near ", " as well "," next to ", " within ");
                    $description = $frontword_list ." ". implode_array($preposition,$keywords_array); //call the new function
                    echo $description;

显示如下内容：

Outstanding car 1  next to  car 2  beside  car 3   near  car 4  amidst  car 5  as well  car 5  within  car 6

如果你有更多的keywords_array而不是你的介词，你可以删除这些行：

unset($prep[$random_index]); //unset used index
$prep = array_values($prep); //reset index values

Answer 2

在这一点上，我的拙见认为你错误地使用了array_rand $ preposition_rand = $ preposition [array_rand（$ preposition）];

你可以尝试这样的事情：

function join_list($a,$b){
  return "$a $b";
}

$keywords_array = array("car 1 "," car 2 "," car 3 "," car 4 "," car 5 "," car 5 "," car 6");
$frontword_list = array("Amazing", "Good-Looking", "Magnificent", "Pretty", "Sparkling", "Awesome", "Imaginative", "Outstanding");
$frontword_list = $frontword_list[array_rand($frontword_list)];

$preposition = array(" alongside "," amidst "," among ", " beside "," including ","  near ", " as well "," next to ", " within ");
shuffle($preposition);
$preposition_rand = array_slice($preposition,0, count($keywords_array)-1);

$description = $frontword_list ." ". implode("",array_map("join_list", $keywords_array, $preposition_rand));
echo $description;

echo "\n";

输出 - 随机变化：汽车2旁边的汽车2旁边的汽车2和汽车5旁边的汽车4以及包括汽车6的汽车5

Array_rand和Implode输出卡住了
