Had a go at simplifying Stomps two functions above. My goal was to get rid of eval, which I achieved for mk_json_object but couldn't achieve this for mk_json_object_one_val:

Code:
mk_json_object(){
   local items rest

   printf -v items '"%s": "%s"' "$1" "$2"
   shift 2
   [ $# -gt 1 ] && printf -v rest ',"%s": "%s"' "$@"
   echo "{ $items$rest }"
}

mk_json_object_one_val() {
   local val="$1"
   shift
   eval set -- "$(printf "\"$val\" \"%s\" " "$@")"
   mk_json_object "$@"
}

MAXDB_FETCH_FIELDS(3)							 1						     MAXDB_FETCH_FIELDS(3)

maxdb_fetch_fields - Returns an array of resources representing the fields in a result set

       Procedural style

SYNOPSIS
mixed maxdb_fetch_fields (resource $result) DESCRIPTION
Object oriented style mixed maxdb_result::fetch_fields (void ) This function serves an identical purpose to the maxdb_fetch_field(3) function with the single difference that, instead of returning one resource at a time for each field, the columns are returned as an array of resources. RETURN VALUES
Returns an array of resources which contains field definition information or FALSE if no field information is available. Object properties +-----------+---------------------------------------------------+ | Property | | | | | | | Description | | | | +-----------+---------------------------------------------------+ | name | | | | | | | The name of the column | | | | |max_length | | | | | | | The maximum width of the field for the result | | | set. | | | | | type | | | | | | | The data type used for this field | | | | | decimals | | | | | | | The number of decimals used (for integer fields) | | | | +-----------+---------------------------------------------------+ EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } $query = "SELECT name, cno from hotel.customer ORDER BY cno"; if ($result = $maxdb->query($query)) { /* Get field information for all columns */ $finfo = $result->fetch_fields(); foreach ($finfo as $val) { printf("Name: %s ", $val->name); printf("Table: %s ", $val->table); printf("max. Len: %d ", $val->max_length); printf("Flags: %d ", $val->flags); printf("Type: %d ", $val->type); } $result->close(); } /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } $query = "SELECT name, cno from hotel.customer ORDER BY cno"; if ($result = maxdb_query($link, $query)) { /* Get field information for all columns */ $finfo = maxdb_fetch_fields($result); foreach ($finfo as $val) { printf("Name: %s ", $val->name); printf("Table: %s ", $val->table); printf("max. Len: %d ", $val->max_length); printf("Flags: %d ", $val->flags); printf("Type: %d ", $val->type); } maxdb_free_result($result); } /* close connection */ maxdb_close($link); ?> The above example will output something similar to: Name: NAME Table: max. Len: 10 Flags: -1 Type: 2 Name: CNO Table: max. Len: 4 Flags: -1 Type: 0 SEE ALSO
