yaz_ccl_conf — Configure CCL parser

### Description

void yaz_ccl_conf ( resource `$id` , array `$config` )

This function configures the CCL query parser for a server with definitions of access points (CCL qualifiers) and their mapping to RPN.

To map a specific CCL query to RPN afterwards call the yaz_ccl_parse() function.

### Parameters

`id`

  The connection resource returned by yaz_connect().

`config`

  An array of configuration. Each key of the array is the name of a CCL field and the corresponding value holds a string that specifies a mapping to RPN.

  The mapping is a sequence of attribute-type, attribute-value pairs. Attribute-type and attribute-value is separated by an equal sign (=). Each pair is separated by white space.

  Additional information can be found on the » CCL page.

### Return Values

No value is returned.

### Examples

In the example below, the CCL parser is configured to support three CCL fields: ti, au and isbn. Each field is mapped to their BIB-1 equivalent. It is assumed that variable $id is the connection ID.

Example#1 CCL configuration

`<?php
$fields = array(
"ti" => "1=4",
"au" => "1=1",
"isbn" => "1=7"
);
yaz_ccl_conf($id, $fields);
?>`
