1. What is XML-RPC?
XML-RPC is a format designed by Userland Software company: it is a format designed to use HTTP protocol transfers XML format file to obtain remote procedure call (Remote Procedure Call) transmission method. The official website is www.xmlrpc.com.
There is a PHP XML-RPCFramework(Collection of classes) is used to use PHP Language to write XML-RPC client and server. The current stable release version is 2.2, and the download address of is http://sourceforge.net/projects/phpxmlrpc/files/phpxmlrpc/2.2.2/xmlrpc -2.2.2.tar.gz/download. In addition, you can also find other s language
XML-RPCwww.xmlrpc.com ??> list, such as Perl, Python. This article will introduce the use of XML-RPC for PHP
class library. 2. System Operation Requirements
The design goals of this class library are scalability and backward compatibility. Therefore, it supports most existing PHP
versions. The minimum required PHP version is 4.2. This library provides a compatibility layer to support PHP 4.0.5 and 4.1. Of course, the official recommendation is to use PHP 5.0 or higher. Note that if you want to use SSL or HTTP 1.1 to communicate with the remote server, you must put "CURL” extension is compiled into PHP. In addition, the native "xmlrpc" extension that comes with PHP is introduced here The XML-RPC class library is not the same thing, so there is no need to compile it into PHP. 3. Introduction to related classes 1.xmlrpcval There are six basic types in XML-RPC Two composite types, the basic types are: int, boolean, string , double, dateTime.iso8601, base6, the composite type is: array, struct. The function of Xmlrpcval is to convert the types in PHP into these types and put them into XML-RPC for transmission. Related methods: scalarVal()：如果$val->kindOf()=="scalar",則直接返回改對(duì)象的PHP對(duì)應(yīng)的值。 2.xmlrpcmsg 相關(guān)函數(shù)： 相關(guān)方法： 相關(guān)方法： 四，一個(gè)實(shí)際例子 在服務(wù)度的interface.php中：

How to handle File Uploads securely in PHP?
Jul 08, 2025 am 02:37 AM
To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

PHP find the position of the last occurrence of a substring
Jul 09, 2025 am 02:49 AM
The most direct way to find the last occurrence of a substring in PHP is to use the strrpos() function. 1. Use strrpos() function to directly obtain the index of the last occurrence of the substring in the main string. If it is not found, it returns false. The syntax is strrpos($haystack,$needle,$offset=0). 2. If you need to ignore case, you can use the strripos() function to implement case-insensitive search. 3. For multi-byte characters such as Chinese, the mb_strrpos() function in the mbstring extension should be used to ensure that the character position is returned instead of the byte position. 4. Note that strrpos() returns f
PHP header location ajax call not working
Jul 10, 2025 pm 01:46 PM
The reason why header('Location:...') in AJAX request is invalid is that the browser will not automatically perform page redirects. Because in the AJAX request, the 302 status code and Location header information returned by the server will be processed as response data, rather than triggering the jump behavior. Solutions are: 1. Return JSON data in PHP and include a jump URL; 2. Check the redirect field in the front-end AJAX callback and jump manually with window.location.href; 3. Ensure that the PHP output is only JSON to avoid parsing failure; 4. To deal with cross-domain problems, you need to set appropriate CORS headers; 5. To prevent cache interference, you can add a timestamp or set cache:f
mysql coalesce function
Jul 09, 2025 am 01:09 AM
The COALESCE function is used to return the first non-null value in the parameter list and is suitable for processing NULL data. 1. The basic usage is to replace the NULL value, such as replacing the empty field with the default contact method; 2. It can be used to set the default value in aggregate query to ensure that 0 is returned instead of NULL when there is no data; 3. It can be used in conjunction with other functions such as NULLIF and IFNULL to enhance data cleaning and logical judgment capabilities.

Parsing XML data in Python
Jul 09, 2025 am 02:28 AM
Processing XML data is common and flexible in Python. The main methods are as follows: 1. Use xml.etree.ElementTree to quickly parse simple XML, suitable for data with clear structure and low hierarchy; 2. When encountering a namespace, you need to manually add prefixes, such as using a namespace dictionary for matching; 3. For complex XML, it is recommended to use a third-party library lxml with stronger functions, which supports advanced features such as XPath2.0, and can be installed and imported through pip. Selecting the right tool is the key. Built-in modules are available for small projects, and lxml is used for complex scenarios to improve efficiency.
How to URL encode a string in PHP with urlencode
Jul 11, 2025 am 03:22 AM
The urlencode() function is used to encode strings into URL-safe formats, where non-alphanumeric characters (except -, _, and .) are replaced with a percent sign followed by a two-digit hexadecimal number. For example, spaces are converted to signs, exclamation marks are converted to!, and Chinese characters are converted to their UTF-8 encoding form. When using, only the parameter values ??should be encoded, not the entire URL, to avoid damaging the URL structure. For other parts of the URL, such as path segments, the rawurlencode() function should be used, which converts the space to . When processing array parameters, you can use http_build_query() to automatically encode, or manually call urlencode() on each value to ensure safe transfer of data. just
