Programming PHP

ob_gzhandler
string ob_gzhandler(string buffer[, int mode])
This function gzip-compresses output before it is sent to the browser. You don’t call this
function directly. Rather, it is used as a handler for output buffering using the ob_start( )
function. To enable gzip-compression, call ob_start( ) with this function’s name:
ob_implicit_flush
void ob_implicit_flush([int flag])
If flag is true or unspecified, turns on output buffering with implicit flushing. When
implicit flushing is enabled, the output buffer is cleared and sent to the client after any
output (such as the printf( ) and echo( ) functions). See Chapter 13 for more information
on using the output buffer.
ob_start
void ob_start([string callback])
Turns on output buffering, which causes all output to be accumulated in a buffer instead of
being sent directly to the browser. If callback is specified, it is a function (called before
sending the output buffer to the client) that can modify the data in any way; the ob_
gzhandler( ) function is provided to compress the output buffer in a client-aware manner.
See Chapter 13 for more information on using the output buffer.
octdec
int octdec(string octal)
Converts octal to its decimal value. Up to a 32-bit number, or 2,147,483,647 decimal
(017777777777 octal), can be converted.
opendir
int opendir(string path)
Opens the directory path and returns a directory handle for the path that is suitable for use
in subsequent readdir( ), rewinddir( ), and closedir( ) calls. If path is not a valid directory,
if permissions do not allow the PHP process to read the directory, or if any other error
occurs, false is returned.
