(If there are broken line breaks and you can't apply it, change the
line stream.avail_in = (uInt) Z_STRLEN_PP(data) to ...(data)+1 in the
gzinflate function).
Please report if it works (and if it doesn't break other things). This
seems to be a rather strange thing in the zlib library ...

Does this script work if you don't provide a compression level?

Receive the following error with only 15 consecutive characters
entered.
Warning: gzinflate: buffer error in
/usr/local/apache/elca_rmg/class.FTemplateExt.php on line 153
What follows is the code updating the SQL files:
$gzsize = strlen($description) + 4; // added 4 more than req'd
$gzcompress = gzdeflate ($description,6);
$gzcompress = addslashes($gzcompress); //Reqd for SQL updates
$query = "UPDATE htmlcontent SET record_nbr = \"$record_nbr\",
gzcompress = \"$gzcompress\", gzsize = $gzsize WHERE record_nbr =
\"$record_nbr\"";
}
general_update($errno,$errmsg,$rowsaffected, $result, $s_synod_id,
$query); // UPDATE the record
*******************************************************
Next I attempt to read the record back and unzip gzcompress
Note that $description consists of 20 'a' characters. Any repetitive
char will do and only 15 to 20 are req'd
*******************************************************
$query = "SELECT * FROM htmlcontent WHERE record_nbr =
\"$record_nbr\"";
general_read($errno, $errmsg,$numrows, $result_html, $s_synod_id,
$query);
if ($numrows > 0) {
if ($row_html = mysql_fetch_array ($result_html)) {
$content = stripslashes($row_html["gzcompress"]);
if (strlen($content) > 0) {
******Error occurs on the following instruction*********
$new = gzinflate($content,$row_html["gzsize"]);
