What can be developed with php?

Basically, most websites on the Internet are developed with PHP. PHP is a server-side HTML-embedded scripting language. Its most powerful and important feature is its database integration layer, which makes it incredibly simple to create a web page that contains database functionality. In HTML files, PHP scripts (syntax similar to Perl or C language) can be referenced using special PHP tags, so that web page producers do not have to rely entirely on HTML to generate web pages. Since PHP is executed on the server side, the client cannot see the PHP code. PHP can complete any task that a CGI script can complete, but its functionality depends on its compatibility with various databases. In addition to using HTTP for communication, PHP can also use IMAP, SNMP, NNTP, and POP3 protocols.
