使用php将图像上载到文件
我想上传一个图像到一个文件使用php。我一直在简化代码，但仍然不起作用。一旦我发现了问题所在，我会重新添加参数。这是我的文件upload.php使用php将图像上载到文件,php,file-upload,Php,File Upload,我想上传一个图像到一个文件使用php。我一直在简化代码，但仍然不起作用。一旦我发现了问题所在，我会重新添加参数。这是我的文件upload.php <html> <body> <form action="upload.php" method="post" enctype="multipart/form-data"> Select image to upload: <input type="file" name="upload" id="u

选择要上载的图像：
我已经创建了“uploads”文件夹，但没有向其中添加图像 首先，您必须确保php.ini中的属性文件_uploads=on 文件 其次，确保将upload_max_filesize设置为所需的大小 然后看看这个代码
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$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 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 ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
