说明

bool yaz_ccl_parse ( resource $id , string $query , array &$result )

This function invokes a CCL parser. It converts a given CCL FIND query to an RPN query which may be passed to the yaz_search() function to perform a search.

To define a set of valid CCL fields call yaz_ccl_conf() prior to this function.

参数

id

The connection resource returned by yaz_connect().

query

The CCL FIND query.

result

If the function was executed successfully, this will be an array containing the valid RPN query under the key rpn.

Upon failure, three indexes are set in this array to indicate the cause of failure:

errorcode - the CCL error code (integer)
errorstring - the CCL error string
errorpos - approximate position in query of failure (integer is character position)

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

Example#1 CCL Parsing

We will try to search using CCL. In the example below, $ccl is a CCL query.


<?php

yaz_ccl_conf($id, $fields);  // see example for yaz_ccl_conf
if (!yaz_ccl_parse($id, $ccl, &$cclresult)) {
    echo 'Error: ' . $cclresult["errorstring"];
} else {
    $rpn = $cclresult["rpn"];
    yaz_search($id, "rpn", $rpn);
}
?>
