制作更优雅的PHP代码

Question

我有一些代码，但我认为它可能更简单。

也许你可以打扰我，做到这一点。

$array_product = array ('1,2,3,4,5','5,7,8,9,5','1,5,7,8,9');
$table = array();

for($i = 0;$i<count($array_product) ;$i++)
{
    $arr = preg_split('/,/',$array_product[$i]);
    foreach($arr as $val)
    {
        $table[$i][]=$val;
    }
}

print_r($table);

谢谢！

Answer 1

$array_product = array ('1,2,3,4,5','5,7,8,9,5','1,5,7,8,9');
$table = array_map(function($val) {
    return explode(",", $val);
}, $array_product);

print_r($table);

array_map() explode()

Answer 2

$table = array_map(function($x){return explode(',',$x);}, $array_product);

Answer 3

您可以将其简化，可读和优化，如下所示：

$arrayProduct = array ('1,2,3,4,5', '5,7,8,9,5', '1,5,7,8,9');
$table = array();
foreach ($arrayProduct as $values) {
    $arr = explode(',', $values);
    $table[] = $arr;
}
print_r($table);
