将多个数组中的分隔值组合起来，形成一个由分隔值组成的转置字符串

Question

我试图将四个字符串(用逗号分隔)的单词混合成一个字符串，如下所示：

$string1 = "apple, banana, grape";
$string2 = "red, yellow, black"; 
$string3 = "north, south, east"; 
$string4 = "april, may, june";  
$output_string = "apple, red, north, april, banana, yellow, south, may, grape, black, east, june";

有什么想法吗？

Answer 1

试试这个(但这不是优化的好方法)，如果元素的顺序很重要，请使用这个

$string1 = "apple, banana, grape";
$string2 = "red, yellow, black"; 
$string3 = "north, south, east"; 
$string4 = "april, may, june";  
$piece1 = explode(",", $string1);
$piece2 = explode(",", $string2);
$piece3 = explode(",", $string3);
$piece4 = explode(",", $string4);

$i = 0;
foreach($piece1 as $element){
$resultArray[] = $element;
$resultArray[] = $piece2[$i];
$resultArray[] = $piece3[$i];
$resultArray[] = $piece4[$i];
$i++;
}
var_dump(implode(",", $resultArray));

结果：

string(75)"苹果，红色，北部，四月，香蕉，黄色，南部，五月，葡萄，黑色，东部，六月">

已编辑。更短的方式：

$i = 0;
foreach($piece1 as $element){
$resultArray.= $element.",".$piece2[$i].",".$piece3[$i].",".$piece4[$i];
$i++;
}
var_dump( $resultArray);

结果将是相同的

Answer 2

我认为您可以使用下面的代码。

$totalString = implode(', ', array($string1, $string2, $string3, $string4));
$splittedValues = explode ( ',', $totalString );
// trim all values
$result = array_map('trim', $splittedValues);
// randomize all values
$result = shuffle($result);
// merge it to a string
$output_string = implode(', ', $result);

祝你好运，

$string1 = "apple, banana, grape";
$string2 = "red, yellow, black"; 
$string3 = "north, south, east"; 
$string4 = "april, may, june";
$myArray = array(
explode(',', $string1),
explode(',', $string2),
explode(',', $string3),
explode(',', $string4),
);
$transposedData = call_user_func_array(
'array_map',
array_merge(
array(NULL),
$myArray
)
);
array_walk(
$transposedData,
function(&$value) {
$value = implode(', ', $value);
}
);
echo implode(',', $transposedData);

Answer 4

您可以创建函数，该函数将接收多个字符串，并且返回随机化的字符串：

function mix_multiple_strings() {
$strings = array();
foreach (func_get_args() as $string) {
$strings = array_merge($strings, explode(', ', $string));
}
shuffle($strings);
return implode(', ', $strings);
}
echo mix_multiple_strings($string1, $string2, $string3, $string4);

演示

或者将按顺序排列字符串的函数：

function arrange_multiple_strings() {
$strings = array();
$n = func_num_args();
foreach (func_get_args() as $i => $string) {
foreach (explode(', ', $string) as $j => $val) {
$strings[$n * $j + $i] = $val;
}
}
ksort($strings);
return implode(', ', $strings);
}
echo arrange_multiple_strings($string1, $string2, $string3, $string4);
