yaz_ccl_conf

Configure CCL parser (PHP 4 >= 4.0.5, PECL yaz:0.9-1.0.9)
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 2673. CCL configuration

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