结合2个php数组？

Question

我该如何组合这两个阵列？

$array1 = array("gif" => "gif", "jpg" => "jpeg", "jpeg" => "jpeg", "png" =>"png");
$array2 = array("gif" => "0", "jpg" => "90", "jpeg" => "90", "png" => "8");

我试过了

$array1 = array("gif" => "gif" => "0", "jpg" => "jpeg" => "90", "jpeg" => "jpeg" => "90", "png" =>"png" => "8");

但当然它没有用,所以任何帮助？

Answer 1

这似乎更有意义:

$arr = array("gif" => array("extension" => "gif", "size" => "90"),
             "jpg" => array("extension" => "jpeg", "size" => "120")

               ...
              );

echo "Extension: " . $arr['gif']['extension'] . " Size or whatever: " . $arr['gif']['size'];

循环遍历:

foreach($arr as $key => $val) {
    echo "Image Type: $key, Extension: " . $val['extension'] . ", Size: " . $val['size'];
}
