# yaz_ccl_conf

(PHP 4 >= 4.0.5, PECL)

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); ?>`
