如何上传.webp格式的图片？

1. 通过HTML表单上传：

在HTML表单中添加input标签，type属性为file，accept属性为image/webp。示例代码如下：

<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" name="fileToUpload" id="fileToUpload" accept="image/webp">
  <input type="submit" value="Upload Image" name="submit">
</form>

2. 通过PHP上传：

在PHP中使用move_uploaded_file函数上传webp图片文件。示例代码如下：

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if ($imageFileType == "webp") {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>
