Question

I have 2 array datas, ("a","b","c") and ("x","y","z"), how to mixed them and out put a result as (ax)|(ay)|(az)|(bx)|(by)|(bz)|(cx)|(cy)|(cz)? (each $array1 + $array2 combine into a new words).

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

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

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

Answer 1

You’ll want to use a nested loop:

$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)
