PHP上传图片接口是指使用PHP编程语言编写的服务器端程序,用于处理客户端上传的图片文件。客户端通常通过HTML表单提交图片文件,服务器端接收并处理这些文件。
以下是一个简单的PHP上传图片接口示例:
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_FILES['image'])) {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// 检查文件是否为图片
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["image"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
} else {
echo "File is not an image.";
}
}
?>
<!DOCTYPE html>
<html>
<head>
<title>Upload Image</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="image">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
