In some circumstances, you may want to send a bzip2 stream to the client.
To do this, you need only do:
<?php
ob_flush();
$bz = bzopen('php://stdout', 'w');
bzwrite($bz, 'some input here');
bzclose($bz);
?>
However, please note, because you are using STDOUT, you need to ob_flush() before actually writing to the stream. Otherwise, you might be sending data before the headers, which will cause errors on both server and client ends, in most cases.
You might be able to use php://output rather than php://stdout, however in my tests (with Linux), php://output doesn't actually work - at all.
bzopen
(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)
bzopen — Abre um arquivo comprimido com bzip2
Descrição
bzopen
( string
$filename
, string $mode
) : resource
Abre um arquivo bzip2 (.bz2) para leitura ou escrita.
O parâmetro filename é o nome do arquivo a ser
aberto. mode é similar ao da função
fopen() (`r' para leitura, `w' para escrita, etc.).
Se esta função falhar, retorna false, do contrário
retorna um ponteiro de arquivo aberto.
Exemplo #1 Exemplo de bzopen()
<?php
$bz = bzopen("/tmp/foo.bz2", "r");
$arquivo_descomprimido = '';
while (!feof($bz)) {
$arquivo_descomprimido .= bzread($bz, 4096);
}
bzclose($bz);
print( "O conteúdo de /tmp/foo.bz2 é: " );
print( "\n<br>\n" );
print( $arquivo_descomprimido );
?>

Warning!
the example show above is _not_ working in every case!
This example will continue reading until there is no more data:
<?PHP
$bz=bzopen('foo.bz2', 'r');
$data="";
do {
$line=bzread($bz, 8092);
if($line!==false)
$data.=$line;
}
while($line);
bzclose($bz);
?>
