Thanks for the reply Jim.
So, you are suggesting this is a parameter problem?
Parameter remains the same for my script. That is the select query. I didn't get what you meant by garbage value.
The query executes within fraction of seconds. Initially, I thought that sleep for 1 second could be cause. But, I don't have anything to support it.

ifx_query
IFX_QUERY(3) 1 IFX_QUERY(3)
ifx_query - Send Informix query
SYNOPSIS
resource ifx_query (string $query, resource $link_identifier, [int $cursor_type], [mixed $blobidarray])
DESCRIPTION
Sends a $query to the currently active database on the server that's associated with the specified link identifier.
For "select-type" queries a cursor is declared and opened. Non-select queries are "execute immediate".
For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows(3).
If the contents of the TEXT (or BYTE) column allow it, you can also use ifx_textasvarchar(1) and ifx_byteasvarchar(1). This allows you to
treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with
blob id's.
With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer
value). You can get the value of the blob as a string or file with the blob functions (see below).
PARAMETERS
o $query
- The query string.
o $link_identifier
- The link identifier.
o $cursor_def
- This optional parameter allows you to make this a scroll and/or hold cursor. It's a bitmask and can be either IFX_SCROLL,
IFX_HOLD, or both or'ed together. I you omit this parameter the cursor is a normal sequential cursor.
o $blobidarray
- If you have BLOB (BYTE or TEXT) columns in the query, you can add a $blobidarray parameter containing the corresponding "blob
ids", and you should replace those columns with a "?" in the query text.
RETURN VALUES
Returns valid Informix result identifier on success, or FALSE on errors.
EXAMPLES
Example #1
Show all rows of the "orders" table as a HTML table
<?php
ifx_textasvarchar(1); // use "text mode" for blobs
$res_id = ifx_query("select * from orders", $conn_id);
if (! $res_id) {
printf("Can't select orders : %s
<br />%s<br />
", ifx_error(), ifx_errormsg());
die;
}
ifx_htmltbl_result($res_id, "border="1"");
ifx_free_result($res_id);
?>
Example #2
Insert some values into the "catalog" table
<?php
// create blob id's for a byte and text column
$textid = ifx_create_blob(0, 0, "Text column in memory");
$byteid = ifx_create_blob(1, 0, "Byte column in memory");
// store blob id's in a blobid array
$blobidarray[] = $textid;
$blobidarray[] = $byteid;
// launch query
$query = "insert into catalog (stock_num, manu_code, " .
"cat_descr,cat_picture) values(1,'HRO',?,?)";
$res_id = ifx_query($query, $conn_id, $blobidarray);
if (! $res_id) {
/* ... error ... */
}
// free result id
ifx_free_result($res_id);
?>
