Also i have tested it on another box having php 5.3.9 - (built: Jan 12 2012 15:14:33) then i saw below error in log:
"child pid 7758 exit signal Segmentation fault (11)"

I need:

1. A complete PHP test script showing the values (if any) in 
$filter_permissions_array.

2. The SQL to create any DB objects used.

3. The versions of the Oracle client libraries and of the database.

Thanks.

Below is my code snippet which i am using : 
$filter_permissions_array = "permissions\n";
$conn=db_connection();
$query = "BEGIN dns_filter_permissions_pkg.insert_customize_brand(:iprange, :is_apply_to_networks_of_nop, :network_filter_id, :ip_check, :filter_permissions, :network_cursor, :return_value); END;";
$stmt = oci_parse($conn, $query);
$network_cursor = oci_new_cursor($conn);
oci_bind_by_name($stmt, "iprange", $ip_cidr_range,20);
oci_bind_by_name($stmt, "is_apply_to_networks_of_nop", $set_network_operator, 225);
oci_bind_by_name($stmt, "network_filter_id", $network_filter_id, 10);
oci_bind_by_name($stmt, "ip_check", $ip_check, 10);
oci_bind_array_by_name($stmt, "filter_permissions", $filter_permissions_array, 10000,-1,SQLT_STR);
oci_bind_by_name($stmt, "network_cursor",  $network_cursor,  -1, OCI_B_CURSOR);
oci_bind_by_name($stmt, "return_value", $return_value, 10);
oci_execute($stmt);
oci_execute($network_cursor);
oci_free_statement($stmt);
oci_close($conn);

The oracle version is 11.2.0.3.0
PHP version is 5.3.9

Thanks,

Without a reproducible testcase (see my previous request #2) I can
only comment on the code:

1. You need error checking in the code.

2. You need SQLT_CHR instead of SQLT_STR in the oci_bind_array_by_name
   call.

3. You should specify the maximum data length instead of -1 in the
   oci_bind_array_by_name call.  Otherwise the length of
   "permissions\n" is used and you might see "ORA-06502 PL/SQL:
   numeric or value error: host bind array too small", depending on
   your schema (again, see my previous request #2).

I can look at this again if I get a complete reproducible testcase.
