创建HTML表单使用POST方法提交数据到PHP脚本；2. PHP通过$_POST接收并处理数据，进行验证和过滤；3. 使用cURL在PHP中编程发送POST请求至API；4. 通过enctype=”multipart/form-data”实现文件上传，PHP用$_FILES处理。
To send data securely to a server for processing, using PHP with POST requests is a common approach. This guide walks through implementing POST requests in PHP, particularly in the context of form handling.

1. Create an HTML Form to Submit Data via POST
This method uses a standard HTML form that sends user input to a PHP script using the POST method. The form defines where and how the data should be submitted.
Create a file named form.htmlUse the method=”post” attribute to ensure data is sent securely without appearing in the URLSet the action attribute to point to your PHP processing script

2. Process POST Data Using PHP
The receiving PHP script retrieves the submitted form data using the $_POST superglobal array. This array holds all data sent via the POST method.
Create a file named process.phpAccess values using $_POST[‘fieldname’]Validate and sanitize inputs before use
Example code:

<?phpif ($_SERVER["REQUEST_METHOD"] == "POST") { $name = htmlspecialchars($_POST['name']); $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);echo "Hello, $name. We've received your email: $email.";
}?>
3. Send POST Requests Programmatically Using cURL
cURL allows sending HTTP POST requests from within PHP scripts, useful when interacting with APIs or submitting data to external services.
Initialize a cURL session with curl_init()Set options like URL, POST fields, and headers using curl_setopt()Execute the request and capture the response
Example code:

'john', 'token' => 'abc123'];$ch = curl_init($url);curl_setopt($ch, CURLOPT_POST, true);curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);if (curl_error($ch)) { echo 'cURL error: ' . curl_error($ch); }curl_close($ch);
echo $response;?>
4. Handle File Uploads via POST in PHP
When uploading files, the form must use enctype="multipart/form-data" and the PHP script must access the $_FILES superglobal to process uploaded files.
Add enctype="multipart/form-data" to the form tagUse an input with type="file" and name attributeCheck for upload errors and move the file to a permanent location
Example code:
立即学习“PHP免费学习笔记（深入）”；
<?phpif ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_FILES["avatar"])) {$targetDir = "uploads/";$targetFile = $targetDir . basename($_FILES["avatar"]["name"]);
if (move_uploaded_file($_FILES["avatar"]["tmp_name"], $targetFile)) { echo "The file ". htmlspecialchars(basename($_FILES["avatar"]["name"])) . " has been uploaded.";} else { echo "Sorry, there was an error uploading your file.";}
}?>
