如何在PHP中生成多个数组中所有项目的组合5个答案

I apologize first, but I've been coding for about 8 hours today to get this last thing done.

我先道歉,但是我今天已经编写了大约8个小时来完成最后一件事。

Code.

$a = array('a', 'c', 'b');

$c = array('a', 'c', 'b');

foreach(array_combine($a, $c) as $k => $v) {
  echo $k.$v;
}

resulting in: aa, bb, cc

结果是:aa,bb,cc

but I want to get@

但我想得到@

aa, ac, ab
ba, bc, bb
ca, cc, cb

I recommend you to use foreach function. Don't use array_combine().

我建议你使用foreach功能。不要使用array_combine()。

function cloop($a, $c) {

$a = array('a', 'b', 'c');
$c = array('d', 'e', 'f');

foreach($a as $A){

  foreach($c as $B) {

    $ab = $A.$B;

  }

}

return $ab;

}

If you want all permutations, then I'm not sure you want to use array_combine(). Just use nested loops, like this:

如果你想要所有的排列,那么我不确定你是否想要使用array_combine()。只需使用嵌套循环,如下所示:

$a = array('a', 'c', 'b');
$c = array('a', 'c', 'b');

foreach($a as $v1){
  foreach($c as $v2) {
    echo $v1.$v2;
  }
}
