在PHP中重用代码（函数？）

Question

Got this bit of code:

if ($_FILES["file1"]["error"] == 0) {
        move_uploaded_file($_FILES["file1"]["tmp_name"], "path/".$_FILES["file1"]["name"]);
    }

I would like to reuse it for more files being uploaded. Was thinking function with some params but it seems i can't get the vars correctly.

Ok fixed it like this:

function upload($file) {

        $allowedExts = array("pdf, jpg, gif, png");
        $extension = end(explode(".", $_FILES[$file]["name"]));

        if (in_array($extension, $allowedExts)) && ($_FILES[$file]["error"] == 0) {
            move_uploaded_file($_FILES[$file]["tmp_name"], "img/new/".$_FILES[$file]["name"]);
        }
    }

And calling via:

upload("file1");

Not sure about the $_FILES loop...

You can loop through the $_FILES array and execute your code for each file, like this:

foreach($_FILES as $file)
{
    if ($file["error"] == 0) {
        move_uploaded_file($file["tmp_name"], "path/".$file["name"]);
    }
}
