PHP笛卡爾產品和標籤

我有以下兩個數組：PHP笛卡爾產品和標籤

<?php 
    $a = array(// actions 
    'left' => 'LEFT', 
    'middle' => 'MIDDLE', 
    'right' => 'RIGHT', 
); 
    $m = array(// modifiers 
    'ctrl' => 'CTRL', 
    'alt' => 'ALT', 
    'shift' => 'SHIFT', 
    'double' => 'DOUBLE', 
); 
?>

我需要得到笛卡爾積與需要相結合的每個組合以及一個警告。如果我向數組添加更多選項，它需要擴展。所以生成的列表應該輸出如下：

<?php 
$options['left'] = 'LEFT'; 
$options['LEFT'] = array(
    'ctrl_left' => 'CTRL+LEFT', 
    'alt_left' => 'ALT+LEFT', 
    'shift_left' => 'SHIFT+LEFT', 
    'double_left' => 'DOUBLE+LEFT', 
    'ctrl_alt_left' => 'CTRL+ALT+LEFT', 
    'ctrl_shift_left' => 'CTRL+SHIFT+LEFT', 
    'ctrl_double_left' => 'CTRL+DOUBLE+LEFT', 
    'alt_shift_left' => 'ALT+SHIFT+LEFT', 
    'alt_double_left' => 'ALT+DOUBLE+LEFT', 
    'ctrl_alt_shift_left' => 'CTRL+ALT+SHIFT+LEFT', 
    'ctrl_alt_double_left' => 'CTRL+ALT+DOUBLE+LEFT', 
    'ctrl_alt_shift_double_left' => 'CTRL+ALT+SHIFT+DOUBLE+LEFT', 
); 
$options['middle'] = 'MIDDLE'; 
$options['MIDDLE'] = array(
    'ctrl_middle' => 'CTRL+MIDDLE', 
    'alt_middle' => 'ALT+MIDDLE', 
    'shift_middle' => 'SHIFT+MIDDLE', 
    'double_middle' => 'DOUBLE+MIDDLE', 
    'ctrl_alt_middle' => 'CTRL+ALT+MIDDLE', 
    'ctrl_shift_middle' => 'CTRL+SHIFT+MIDDLE', 
    'ctrl_double_middle' => 'CTRL+DOUBLE+MIDDLE', 
    'alt_shift_middle' => 'ALT+SHIFT+MIDDLE', 
    'alt_double_middle' => 'ALT+DOUBLE+MIDDLE', 
    'ctrl_alt_shift_middle' => 'CTRL+ALT+SHIFT+MIDDLE', 
    'ctrl_alt_double_middle' => 'CTRL+ALT+DOUBLE+MIDDLE', 
    'ctrl_alt_shift_double_middle' => 'CTRL+ALT+SHIFT+DOUBLE+MIDDLE', 
); 

$options['right'] = 'RIGHT'; 
$options['RIGHT'] = array(
    'ctrl_right' => 'CTRL+RIGHT', 
    'alt_right' => 'ALT+RIGHT', 
    'shift_right' => 'SHIFT+RIGHT', 
    'double_right' => 'DOUBLE+RIGHT', 
    'ctrl_alt_right' => 'CTRL+ALT+RIGHT', 
    'ctrl_shift_right' => 'CTRL+SHIFT+RIGHT', 
    'ctrl_double_right' => 'CTRL+DOUBLE+RIGHT', 
    'alt_shift_right' => 'ALT+SHIFT+RIGHT', 
    'alt_double_right' => 'ALT+DOUBLE+RIGHT', 
    'ctrl_alt_shift_right' => 'CTRL+ALT+SHIFT+RIGHT', 
    'ctrl_alt_double_right' => 'CTRL+ALT+DOUBLE+RIGHT', 
    'ctrl_alt_shift_double_right' => 'CTRL+ALT+SHIFT+DOUBLE+RIGHT', 
); 
?>

你是否建議鏈接的答案會爲此工作？被問到的問題似乎與我所能說的沒有相同的要求。 – 2012-04-12 22:06:12

它可能會讓你知道你需要做什麼。您的問題名稱和其他問題非常相似。 – Jonathan 2012-04-12 22:09:10

我終於搞清楚了。我對strpos（）和我的爆炸（'_'...）的測試並不完全滿意，但它工作並做我所需要的。

您的要求是非常有選擇性的，並且不包含完整的組合，例如alt_double_left但shift_double_left未列出

我做了什麼，以創建一個例外列表你...

變量

$a = array (// actions 
     'left' => 'LEFT', 
     'middle' => 'MIDDLE', 
     'right' => 'RIGHT' 
); 

$m = array (// modifiers 
     'ctrl' => 'CTRL', 
     'alt' => 'ALT', 
     'shift' => 'SHIFT', 
     'double' => 'DOUBLE' 
); 

$exceptions = array (
     array (
       "shift", 
       "double" 
     ) , 

     array (
       "double", 
       "ctrl" 
     ), 


     array (
       "double", 
       "alt" 
     ) 
); 

$mc = power_perms (array_keys ($m)); 
$options = array();

循環

echo "<pre>"; 

foreach ($a as $aKey => $aValue) { 
    $options [$aValue] = isset ($options [$aKey]) ? $options [$aKey] : array(); 
    foreach ($mc as $mKey => $mValue) { 
     $cKey = implode ("_", $mValue); 
     $cKey .= "_" . $aKey; 

     $cValue = implode ("+", $mValue); 
     $cValue = strtoupper ($cValue . "+" . $aValue); 
     if (eCheck ($exceptions, $cKey)) { 
      continue; 
     } 
     $options [$aValue] [$cKey] = $cValue; 

    } 
} 

print_r ($options);

     } 
     if (count ($out) >= $minLength) { 
      $return [] = $out; 
     } 
    }

function array_delete_by_key(&$array, $delete_key, $use_old_keys = FALSE) { 

    unset ($array [$delete_key]); 

    if (! $use_old_keys) { 
     $array = array_values ($array);

如果我錯過了一個組合，那麼這是一個oversite。我不需要有選擇性，我需要做所有這些，但我不希望有兩種相同的組合，像shift_ctrl_alt_left＆shift_alt_ctrl_left這樣的不同順序，就像你的例子。任何改變這一點的想法？ – 2012-04-12 23:31:34

只需將'array（「shift」，「alt」）和'array（「shift」，「ctrl」）'添加到例外列表中即可......就這麼簡單 – Baba 2012-04-12 23:37:39

只是澄清了爲什麼我沒有選擇這個解決方案，維護第三個排除列表對我來說是不合理的。我也不希望出現任何重複的條目，例如shift_ctrl_alt_left＆shift_alt_ctrl_left，它們只是重新排序的同一個東西。感謝您的努力。 – 2012-04-17 00:12:53

這應該工作

foreach($a as $key=>$val){ 
    $options[$key]=$val; 
    $m_temp=$m; 
    while(is_array($m_temp)){ 
     $options[$val][implode('_', $m_temp).'_'.$key] = implode('_', array_value($m_temp)).'_'.$val; 
     $m_temp=array_pop($m_temp); 
    } 
    $m=$m_temp; 
}
