also i tried with echo $var | sed -n '/^[0-9][0-9]*$/p' same thing happened
any thing consist of 0-9 should be considered as numeric , this sed expression working fine except for the value 445$$343 or 23$899 some thing like this which contain $ , it is considering that as numeric .
It should work fine. Its working fine for me. I dont know whats happening in your case

LEARN ABOUT PHP
fbsql_fetch_array
FBSQL_FETCH_ARRAY(3) 1 FBSQL_FETCH_ARRAY(3)
fbsql_fetch_array - Fetch a result row as an associative array, a numeric array, or both
SYNOPSIS
array fbsql_fetch_array (resource $result, [int $result_type])
DESCRIPTION
fbsql_fetch_array(3) is a combination of fbsql_fetch_row(3) and fbsql_fetch_assoc(3).
An important thing to note is that using fbsql_fetch_array(3) is NOT significantly slower than using fbsql_fetch_row(3), while it provides
a significant added value.
PARAMETERS
o $
result -A result identifier returned by fbsql_query(3) or fbsql_db_query(3).
o $result_type
- A constant and can take the following values: FBSQL_ASSOC, FBSQL_NUM, or FBSQL_BOTH. When using FBSQL_BOTH, in addition to
storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names
as keys.
RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.
If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the
same name, you must the numeric index of the column or make an alias for the column.
select t1.f1 as foo t2.f1 as bar from t1, t2
EXAMPLES
Example #1
fbsql_fetch_array(3) example
<?php
fbsql_connect($host, $user, $password);
$result = fbsql_db_query("database", "select user_id, fullname from table");
while ($row = fbsql_fetch_array($result)) {
echo "user_id: " . $row["user_id"] . "<br />
";
echo "user_id: " . $row[0] . "<br />
";
echo "fullname: " . $row["fullname"] . "<br />
";
echo "fullname: " . $row[1] . "<br />
";
}
fbsql_free_result($result);
?>
