bzread — Binary safe bzip2 file read

### Description

string bzread ( resource `$bz` [, int `$length` = 1024 ] )

bzread() reads from the given bzip2 file pointer.

Reading stops when `length` (uncompressed) bytes have been read or EOF is reached, whichever comes first.

### Parameters

`bz`

  The file pointer. It must be valid and must point to a file successfully opened by bzopen().

`length`

  If not specified, bzread() will read 1024 (uncompressed) bytes at a time. A maximum of 8192 uncompressed bytes will be read at a time.

### Return Values

Returns the uncompressed data, or `FALSE` on error.

### Examples

Example #1 bzread() example

`<?php
$file = "/tmp/foo.bz2";
$bz = bzopen($file, "r") or die("Couldn't open $file");
$decompressed_file = '';
while (!feof($bz)) {
$decompressed_file .= bzread($bz, 4096);
}
bzclose($bz);
echo "The contents of $file are: <br />\n";
echo $decompressed_file;
?>`
