  1. PHP Array Introduction The array functions allow you to manipulate arrays. PHP supports both simple and multi-dimensional arrays. There are also specific functions for populating arrays from database queries. Installation The array functions are part of the PHP core. There is no installation needed to use these functions. PHP Array Functions PHP: indicates the earliest version of PHP that supports the function. Function array() array array a r ray array array array array array array array array array array array a r ray array array change key chunk() combine() case() count values() diff() diff assoc() diff key() diff uassoc() diff ukey() fill() filter() flip() intersect() intersect intersect intersect intersect assoc() key ( ) uassoc() ukey() Description Creates an array Returns an array with all keys in lowercase or uppercase Splits an array into chunks of arrays Creates an array by using one array for keys and another for its values Returns an array with the number of occurrences for each value Compares array values, and returns the differences Compares array keys and values, and returns the differences Compares array keys, and returns the differences Compares array keys and values, with an additional user- made function check, and returns the differences Compares array keys, with an additional user-made function check, and returns the differences Fills an array with values Filters elements of an array using a user-made function Exchanges all keys with their associated values in an array Compares array values, and returns the matches Compares array keys and values, and returns the matches Compares array keys, and returns the matches Compares array keys and values, with an additional user- made function check, and returns the matches Compares array keys, with an additional user-made function check, and returns the matches PHP 3 4 4 5 4 4 4 5 5 5 4 4 4 4 4 5 5 5

The standard it is based on is the Julian day count (Julian day count is a count of days starting from January 1, 4713 B.C.). Note that the Julian day count is not the same as the Julian calendar! Note: To convert between calendar formats, you must first convert to Julian day count, then to the calendar format. Installation The windows version of PHP has built-in support for the calendar extension. So, the calendar functions will work automatically. However, if you are running the Linux version of PHP, you will have to compile PHP with - enable-calendar to get the calendar functions to work. PHP Calendar Functions PHP: indicates the earliest version of PHP that supports the function.

The FTP functions are used to open, login and close connections, as well as upload, download, rename, delete, and get information on files from file servers. Not all of the FTP functions will work with every server or return the same results. The FTP functions became available with PI-IP 3. These functions are meant for detailed access to an FTP server. If you only wish to read from or write to a file on an FTP server, consider using the ftp:// wrapper with the Filesystem functions. Installation The windows version of PHP has built-in support for the FTP extension. So, the FTP functions will work automatically. However, if you are running the Linux version of PHP, you will have to compile PHP with - enable-ftp(PHP 4+) or --with-ftp (PHP 3) to get the FTP functions to work.

Installation For the MySQL functions to be available, you must compile PHP with MySQL support. For compiling, use --with-mysql=DIR (the optional DIR points to the MySQL directory). Note: For full functionality of MySQL versions greater than 4.1. , use the MySQLi extension instead. If you would like to install both the mysql extension and the mysqli extension you should use the same client library to avoid any conflicts. Installation on Linux Systems PHP 5+: MySQL and the MySQL library is not enabled by default. Use the --with- mysql=DIRconfigure option to include MySQL support and download headers and libraries fromwww.mysql.com. Installation on Windows Systems PHP 5+: MySQL is not enabled by default, so the php_mysql.dll must be enabled inside of php.ini. Also, PHP needs access to the MySQL client library. A file named libmysql.dll is included in the Windows PHP distribution, and in order for PHP to talk to MySQL this file needs to be available to the Windows systems PATH. 3 5 5 3 3 3 PHP 5
  25. To enable any PHP extension, the PHP extension_dir setting (in the php.ini file) should be set to the directory where the PHP extensions are located. An example extension_dir value is c:\php\ext. Note: If you get the following error when starting the web server: "Unable to load dynamic library './php_mysql.dll"', this is because php_mysql.dll or libmysql.dll cannot be found by the system. Runtime Configuration The behavior of the MySQL functions is affected by settings in the php.ini file. MySQL configuration options: "-1" "-1" Name mysql.allow_persistent mysql.max_persistent mysql.max_links mysql.trace_mode mysql.default_port mysql.default_socket mysql.default_host mysql.default_user Default "1" NULL NULL NULL NULL Description Whether or not to allow persistent connections The maximum number of persistent connections per process The maximum number of connections per process (persistent connections included) Trace mode. When set to "1", warnings and SQL-errors will be displayed. Available since PHP 4.3 The default TCP port number to use The default socket name to use. Available since PHP 4.0.1 The default server host to use (doesn't apply in SQL safe mode) The default user name to use (doesn't apply in SQL safe mode) The default password to use (doesn't apply in SQL safe mode) Connection timeout in seconds Changeable PI-IP INI SYSTEM PHP INI SYSTEM PI-IP INI SYSTEM PHP INI ALL PHP INI ALL Pi-IP INI ALL PI-IP INI ALL PI-IP INI ALL PI-IP INI ALL PHP INI ALL mysql.default_password NULL mysql.connect_timeout "60" Resource Types There are two resource types used in the MySQL extension. The first one is the link_identifier for a database connection, the second is a resource which holds the result of a query. Note: Most MySQL functions accept link_identifier as the last optional parameter. If it is not provided, the last opened connection is used.

XML is a data format for standardized structured document exchange. More information on XML can be found in our XML Tutorial. This extension uses the Expat XML parser. Expat is an event-based parser, it views an XML document as a series of events. When an event occurs, it calls a specified function to handle it. Expat is a non-validating parser, and ignores any DTDs linked to a document. However, if the document is not well formed it will end with an error message. Because it is an event-based, non validating parser, Expat is fast and well suited for web applications. The XML parser functions lets you create XML parsers and define handlers for XML events. Installation The XML functions are part of the PHP core. There is no installation needed to use these functions.
