This function allows you to use different sets of databases within a session.

italic can be TRUE or FALSE, and sets whether the font should be italic.

underline can be TRUE or FALSE, and sets whether the font should be underlined.

Sets the file position indicator for fp to the beginning of the file stream.

Sets the specified SNMP object value, returning TRUE on success and FALSE on error.

Sets an option on the specified context. value is set to option for wrapper

Sets the timeout value on stream, expressed in the sum of seconds and microseconds.

Sets the file position indicator for zp to the beginning of the file stream.

ncolors sets the maximum number of colors that should be retained in the palette.

strikeout can be TRUE or FALSE, and sets whether the font should be striked out.

Sets the number of top level rows to be prefetched. The default value is 1 row.

This module contains an interface to the GNU Recode library, version 3.5. The GNU Recode library converts files between various coded character sets and surface encodings. When this cannot be achieved exactly, it may get rid of the offending characters or fall back on approximations. The library recognises or produces nearly 150 different character sets and is able to convert files between almost any pair. Most RFC 1345 character sets are supported.

Sets the fill to bitmap clipped, empty spaces will be filled by the bitmap given by the bitmapid parameter.

Sets an attribute with name name ot the given value. If the attribute does not exist, it will be created.

This function sets the default scale parameter for all subsequent bc math functions that do not explicitly specify a scale parameter.

Return the square root of the operand. The optional scale parameter sets the number of digits after the decimal place in the result.

Each pair of escape sequences partitions the complete set of characters into two disjoint sets. Any given character matches one, and only one, of each pair.

The function sets the following options for the current connection. handle must be a valid handle to a printer. For option can be one of the following constants

The function enumerates available printers and their capabilities. level sets the level of information request. Can be 1,2,4 or 5. enumtype must be one of the following predefined constants

This sets the specified index in the palette to the specified color. This is useful for creating flood fill like effects in paletted images without the overhead of performing the actual flood fill.

This function returns the given string converted from one Cyrillic character set to another. The from and to arguments are single characters that represent the source and target Cyrillic character sets. The supported types are

This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. This helps prevent poorly written scripts from tying up the server. The default setting is 30.

Sets the value of the given configuration option. Returns the old value on success, FALSE on failure. The configuration option will keep this new value during the script's execution, and will be restored at the script's ending.

Parses str as if it were the query string passed via an URL and sets variables in the current scope. If the second parameter arr is present, variables are stored in this variable as an array elements instead.

The seventh parameter timelimit sets the number of seconds how long is spend on the search. Setting this to 0 means no limit. NOTE This parameter can NOT override server side preset timelimit. You can set it lower though.

Sets the file position indicator for the file referenced by fp.The new position, measured in bytes from the beginning of the file, is obtained by adding offset to the position specified by whence, whose values are defined as follows

Sets the namespace of a node to uri. If there is already a namespace declaration with the same uri in one of the parent nodes of the node, the prefix of this is taken, otherwise it will take the one provided in the optional parameter prefix or generate a random one.

The connection id returned by this functions is needed by other ODBC functions. You can have multiple connections open at once. The optional fourth parameter sets the type of cursor to be used for this connection. This parameter is not normally needed, but can be useful for working around problems with some ODBC drivers.

This function sets whether a client disconnect should cause a script to be aborted. It will return the previous setting and can be called without an argument to not change the current setting and only return the current setting. See the Connection Handling section in the Features chapter for a complete description of connection handling in PHP.

This function checks in an object or a whole hiearchie of objects. The parameters array contains the required element 'objectIdentifier' and the optional element 'version', 'comment', 'mode' and 'objectQuery'. 'version' sets the version of the object. It consists of the major and minor version separated by a period. If the version is not set, the minor version is incremented. 'mode' can be one of the following values
