Question

我有3个阵列:

$array1 = array (1 =>  Hello  , 2 =>  nice  3 =>  how );
$array2 = array (1 =>  there  , 2 =>  to  3 =>  are );
$array3 = array (1 =>  champ  , 2 =>  meet  3 =>  you );

and i want to output a string that combines let s say from all the first keys of each array. e.g:

 echo "Hello there champ"
 echo "nice to meet"

How can i do that? The number of values in those arrays will always be identical since these are pulled from a table.

提前感谢。

Answer 1

echo $array1[1] .     . $array2[1] .     . $array3[1]; // hello there champ 
echo $array1[2] .     . $array2[2] .     . $array3[2]; // nice to meet

Answer 2

像这样吗?

function merge() {
    $arrays = func_get_args();
    $count = count($arrays[0]);

    for ($i = 0; $i < $count; $i++) {
        foreach ($arrays as $array) {
            echo $array[$i];
        }

        echo "<br />";
    }
}

$array1 = array (1 =>  helo  , 2 =>  nice  3 =>  how );
$array2 = array (1 =>  there  , 2 =>  to  3 =>  are );
$array3 = array (1 =>  champ  , 2 =>  meet  3 =>  you );

merge($array1, $array2, $array3);
