When using the infor syteline ERP system, when system maintenance is required, we need to notify all users to exit the system. During the maintenance period, user login is prohibited. In this case, we need to lock the user.For this problem, many administrators will openUsersWindow, switchLogin informationLabelUser Login statusIs changed to disabled.
After system maintenance is completed, change it back. This method can only be applied to a small numb
As XML continues to heat up, PHP provides a large number of standard libraries (class libraries) dedicated to XML processing to manipulate XML. For example, dom xml extension rewriting, SimpleXML extension, SOAP extension, and XMLReader and XMLWrite extension of PHP5.1.
1. Use SimpleXML to manipulate XML
There are two traditional approaches to processing XML files: SAX and DOM. Based on the event trigger mechanism, SAX performs a scan on the XML file to complete the processing. DOM constructs th
