The yaz_record() function inspects a record in the current result set at the position specified by parameter pos.
The connection resource returned by yaz_connect().
The record position. Records positions in a result set are numbered 1, 2, ... $hits where $hits is the count returned by yaz_hits().
The type specifies the form of the returned record.
Note:
It is the application which is responsible for actually ensuring that the records are returned from the Z39.50/SRW server in the proper format. The type given only specifies a conversion to take place on the client side (in PHP/YAZ).
Besides conversion of the transfer record to a string/array, PHP/YAZ it is also possible to perform a character set conversion of the record. Especially for USMARC/MARC21 that is recommended since these are typically returned in the character set MARC-8 that is not supported by browsers, etc. To specify a conversion, add ; charset=from, to where from is the original character set of the record and to is the resulting character set (as seen by PHP).
Returns the record at position pos or an empty string if no record exists at the given position.
If no database record exists at the given position an empty string is returned.
Consider this GRS-1 record:
(4,52)Robert M. Pirsig
(4,70)
(4,90)
(2,7)Transworld Publishers, ltd. If this record is present at position $p, then
<?php $ar = yaz_record($id, $p, "array"); print_r($ar); ?>
Array
(
[0] => Array
(
[0] => (4,52)
[1] => Robert M. Pirsig
)
[1] => Array
(
[0] => (4,70)
)
[2] => Array
(
[0] => (4,70)(4,90)
)
[3] => Array
(
[0] => (4,70)(4,90)(2,7)
[1] => Transworld Publishers, ltd.
)
)
The following PHP snippet returns a MARC21/USMARC record as MARCXML. The original record is returned in marc-8 (unknown to most XML parsers), so we convert it to UTF-8 (which all XML parsers must support).
<?php $rec = yaz_record($id, $p, "xml; charset=marc-8,utf-8"); ?>
The record $rec can be processed with the Sablotron XSLT processor as follows:
<?php
$xslfile = 'display.xsl';
$processor = xslt_create();
$parms = array('/_xml' => $rec);
$res = xslt_process($processor, 'arg:/_xml', $xslfile, NULL, $parms);
xslt_free($processor);
$res = preg_replace("'</?html[^>]*>'", '', $res);
echo $res;
?>
For PHP 5 the XSL extension must be used instead of Sablotron XSLT.
