gzread - Binary-safe gz-file read

SYNOPSIS

       string gzread (resource	$zp, int  $length)

DESCRIPTION

       gzread(3)  reads  up to $length bytes from the given gz-file pointer. Reading stops when $length (uncompressed) bytes have been read or EOF
       is reached, whichever comes first.

PARAMETERS

	      o $zp
		- The gz-file pointer. It must be valid, and must point to a file successfully opened by gzopen(3).

	      o $length
		- The number of bytes to read.

RETURN VALUES

	The data that have been read.

EXAMPLES

       Example #1

	      gzread(3) example

	      <?php
	      // get contents of a gz-file into a string
	      $filename = "/usr/local/something.txt.gz";
	      $zd = gzopen($filename, "r");
	      $contents = gzread($zd, 10000);
	      gzclose($zd);
	      ?>

GZOPEN(3)								 1								 GZOPEN(3)

gzopen - Open gz-file

SYNOPSIS

       resource gzopen (string	$filename, string  $mode, [int	$use_include_path])

DESCRIPTION

	Opens a gzip (.gz) file for reading or writing.

       gzopen(3)  can  be  used to read a file which is not in gzip format; in this case gzread(3) will directly read from the file without decom-
       pression.

PARAMETERS

	      o $filename
		- The file name.

	      o $mode
		- As in fopen(3) ( rb or wb) but can also include a compression level ( wb9) or a strategy: f for filtered data as in wb6f, h  for
		Huffman only compression as in wb1h. (See the description of deflateInit2 in zlib.h for more information about the strategy param-
		eter.)

	      o $use_include_path
		- You can set this optional parameter to 1, if you want to search for the file in the include_path too.

RETURN VALUES

	Returns a file pointer to the file opened, after that, everything you read from this file descriptor will  be  transparently  decompressed
       and what you write gets compressed.

	If the open fails, the function returns FALSE.

EXAMPLES

       Example #1

	      gzopen(3) Example

	      <?php
	      $fp = gzopen("/tmp/file.gz", "r");
	      ?>

SEE ALSO

       gzclose(3).
