Discussion: array2xml and xml2array and the mutual conversion of xml and array_PHP tutorial
When PHP is working as a back-end server, it often encounters this situation. It needs to parse the xml file from the front-end and return the data in xml format. In this case, the conversion between xml and the associative array in PHP is Very frequent thing. For example, flex and other client programs often use this method to interact with the server. The following are two methods I have summarized, which greatly simplify the workload of converting xml and array.
/**
*
* 将简单数组转化为简单的xml
* @param string $data 要进行转化的数组
* @param string $tag 要使用的标签
* @example
* $arr = array(
'rtxAccount'=>'aaron','ipAddr'=>'192.168.0.12',
'conferenceList'=>array('conference'=>
array(
array('conferenceId'=>1212,'conferenceTitle'=>'quanshi 444','smeAccount'=>'http://www.jb51.net'),
array('conferenceId'=>454,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
array('conferenceId'=>6767,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
array('conferenceId'=>232323,'conferenceTitle'=>'quanshi uuu','smeAccount'=>'http://www.jb51.net'),
array('conferenceId'=>8989,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
array('conferenceId'=>1234343212,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net')
)
)

PHP: Handling Databases and Server-Side Logic
Apr 15, 2025 am 12:15 AM
PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.
