PHP Upload image with timestamp filename Strict Standard Error

本文关键字：文件名图像时间戳 PHP | 更新日期: 2023-09-27

我有下面的脚本，当它运行时，我得到一个关于严格标准的错误，有人可以帮助吗?我正试图将当前时间戳设置为文件名，以便也是。

<br /> <b>Strict Standards</b>:  Only variables should be passed by
reference in
<b>/home/user/public_html/domain.com/upload.php</b>
on line <b>15</b><br /> Upload: screenshot-05.png<br />Type:
image/png<br />Size: 49.2109375 Kb<br />Stored in: uploads/1401352853

PHP

if(empty($_FILES['file'])) {
  exit();
}

$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ($_FILES["file"]["type"] == "image/gif" || $_FILES["file"]["type"] == "image/jpg" || $_FILES["file"]["type"] == "image/jpeg" || $_FILES["file"]["type"] == "image/png" && $_FILES["file"]["size"] < 2500000 && in_array($extension, $allowedExts)) {
    if ($_FILES["file"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br />";
    } else {
        $unixtime = time();
        $fname = 'uploads/'. $unixtime;
        move_uploaded_file($_FILES["file"]["tmp_name"], $fname);
        echo "Upload: " . $_FILES["file"]["name"] . "<br />";
        echo "Type: " . $_FILES["file"]["type"] . "<br />";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
        echo "Stored in: " . $fname;
    }
} else {
    echo "Invalid file type";
}

编辑:第15行是-> $extension = end(explode(".", $_FILES["file"]["name"]));

$bits = explode(".", $_FILES["file"]["name"]);
$extension = end($bits);
