Question

我有PHP代码上传照片。可以使用代码$check["mime"]提及照片类型，结果如下：The file image/png has been uploaded. 我想将其转换为 .png文件已上传。 这可能是什么？

如果困难，除了使用MIME之外还有其他方法吗？

以下是代码：

<?php
$target_dir = image/";
$imglo = $check["mime"];
$target_file = $target_dir . $imglo;
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". $imglo . " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

<form method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

创建一些字典，例如

$mime_captions = array(
    'image/png' => '.png', 
    'image/jpg' => '.jpg',
    // other mimes
);

在那之后，知道mime-type你可以获得正确的标题：

echo $mime_captions['image/png'];

代码可以更改为：

echo "The file ". $mime_captions[$imglo] . " has been uploaded.";

或者，如果您的哑剧始终以image/子字符串开头 - 请使用str_replace：

echo "The file ". str_replace('image/', '.', $imglo) . " has been uploaded.";
