What can PHP do?

At the most basic level, PHP can do anything any other CGI program can do, such as collect form data, generate dynamic page content, or send and receive cookies.

Perhaps the strongest and most significant feature in PHP is its support for a wide range of databases. Writing a database-enabled web page is incredibly simple. The following databases are currently supported:

Adabas DInterBasePostgreSQL
dBaseFrontBaseSolid
EmpressmSQLSybase
FilePro (read-only)Direct MS-SQLVelocis
IBM DB2MySQLUnix dbm
InformixODBC 
IngresOracle (OCI7 and OCI8) 

PHP also has support for talking to other services using protocols such as IMAP, SNMP, NNTP, POP3, HTTP and countless others. You can also open raw network sockets and interact using other protocols.
