我该怎么做？这些不起作用：

if(empty($_FILES)){
  echo "there is no file uploaded";
  exit;
} else {
  echo "there is file";
}

if(sizeof($_FILES)!=0){
  echo "there is file";
} else {
  echo "there is no file";
}

尝试

样本 ：

<?php

if (isset ( $_FILES ['image'] )) {
    if ($_FILES ["image"] ["error"] == UPLOAD_ERR_OK) {
        echo "File Was Uploaded AND OK";
    } else {
        echo "File Was Uploaded but BAD";
    }
} else {
    echo "No File Uploaded";
}

?>

<form method="post" enctype="multipart/form-data">
    <label for="file">Filename 1:</label> <input type="file" name="image"
        id="file" /> <br /> <input type="submit" name="submit" value="Submit" />
</form>

您可以使用 is_array($_FILES) 检查它是否包含数组格式的文件信息
