Example #1 Decompressing a String
<?php
$start_str
=
"This is not an honest face?"
;
$bzstr
=
bzcompress
(
$start_str
);
echo
"Compressse String: "
;
echo
$bzstr
;
echo
"\n<br />\n"
;
$str
=
bzdecompress
(
$bzstr
);
echo
"Decompressed String: "
;
echo
$str
;
echo
"\n<br />\n"
;
?>
I spent a while to sort out some integuer resuls of the bzdecompress, so maybe it'll be useful for somebody else also...
