yaz_ccl_conf

(PHP 4 >= 4.0.5, PECL yaz >= 0.9.0)

Configure CCL parser

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:

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.

Returns:

No value is returned.

Examples:

CCL configuration

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.

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