The current possible PCRE modifiers are listed below. The names in parentheses refer to internal PCRE names for these modifiers.

瞰赽 1. Query with duplicate field names

The names of several functions are not fixed, yet.

All entries are accessible by using their documented field names.

The case of the returned column names will not be changed.

It provides info about columns, such as field names and field types.

The case of the returned column names will be changed to uppercase.

The case of the returned column names will be changed to lowercase.

Column names for queries on an Oracle database are returned in lowercase.

This function returns the names of all the modules compiled and loaded in the PHP interpreter.

These services, with names like Bokee.com, Blogbus.com and Blogcn.com, all comply with Chinese government censorship requirements.

Additionally, method names in PHP are not case sensitive, potentially increasing the number of overloads to select from.

The array consists of pairs. Elements with even index numbers contain category paths, odd elements contain corresponding category names.

Returns the column names that comprise the primary key for a table. Returns an ODBC result identifier or FALSE on failure.

It effects that the field values can be accessed with the respective column names used as keys to the returned object's data property.

ע You may use these constant names in php.ini but not outside of PHP, like in httpd.conf, where you'd use the bitmask values instead.

Returns a string containing a month name. mode tells this function which calendar to convert the Julian Day Count to, and what type of month names are to be returned.

Sometimes it is convenient to be able to have variable variable names. That is, a variable name which can be set and used dynamically. A normal variable is set with a statement such as

蛁 A backwards incompatible change happened in PHP 4.0 when PHP configuration directive ibase.timeformat was renamed to ibase.timestampformat and directives ibase.dateformat and ibase.timeformat were added, so that the names would match better their functionality.

All other values are converted to an array that contains the specific source value in the element with the key 0.

ע There is no ODBC involved when connecting to the above databases. The functions that you use to speak natively to them just happen to share the same names and syntax as the ODBC functions. The exception to this is iODBC. Building PHP with iODBC support enables you to use any ODBC compliant drivers with your PHP applications. iODBC is maintained by OpenLink Software. More information on iODBC, as well as a HOWTO, is available at www.iodbc.org.
