我有3个变量，每个变量都包含不同的信息，并从动态文本文件中发送值。我想把它们放在一个关联的多维数组中。
让我们说：
$product sends car, truck, train, etc.
$price sends 1000, 3000, 1500, etc.
$year sends 1997, 1980, 2008, etc.
当我执行print_r（myarray）时，如何创建一个生成数组的函数：
Array (
[0] => Array ( [product] => car [price] => 1000 [year] => 1997 )
[1] => Array ( [product] => truck [price] => 3000 [year] => 1980 )
[2] => Array ( [product] => train [price] => 1500 [year] => 2008 )) and so on.
