PHP 2的foreach結果混合

Question

我有2 array datas，("a","b","c")和("x","y","z")，如何把它們混合和出把結果作爲(ax)|(ay)|(az)|(bx)|(by)|(bz)|(cx)|(cy)|(cz)？ （每個$array1 + $array2合併成一個新單詞）。

$array1 = array("a","b","c"); 
foreach($array1 as $data1){ 

} 
$array2 = array("x","y","z"); 
foreach($array2 as $data2){ 

} 
//$output = '(ax)|(ay)|(az)|(bx)|(by)|(bz)|(cx)|(cy)|(cz)'; 

Answer 1

你要使用嵌套循環：

$items = array(); 

foreach($array1 as $a) 
{ 
    foreach($array2 as $b) 
    { 
     $items[] = '(' . $a . $b . ')'; 
    } 
} 
echo implode('|', $items); // (ax)|(ay)|(az)|(bx)|(by)|(bz)|(cx)|(cy)|(cz) 

Answer 2

<?php 

$array1 = array("a","b","c"); 
$array2 = array("x","y","z"); 

$array3 = array(); 

foreach($array1 as $data1){ 
    foreach($array2 as $data2){ 
     $array3[] = "($data1$data2)"; 
    } 
} 

echo implode('|', $array3); 

// (ax)|(ay)|(az)|(bx)|(by)|(bz)|(cx)|(cy)|(cz) 

Answer 3

$array = array(); 
$array1 = array("a","b","c"); 
$array2 = array("x","y","z"); 
foreach($array1 as $data1){ 
foreach($array2 as $data2){ 
    $array[] = '('.$data1.$data2.')'; 
} 
} 
echo implode('|', $array);
