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>
答案 0 :(得分:0)
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.";
