YAZ_SCAN(3) 1 YAZ_SCAN(3) yaz_scan - Prepares for a scan SYNOPSIS
void yaz_scan (resource $id, string $type, string $startterm, [array $flags]) DESCRIPTION
This function prepares for a Z39.50 Scan Request on the specified connection. To actually transfer the Scan Request to the server and receive the Scan Response, yaz_wait(3) must be called. Upon completion of yaz_wait(3) call yaz_error(3) and yaz_scan_result(3) to handle the response. PARAMETERS
o $id - The connection resource returned by yaz_connect(3). o $type - Currently only type rpn is supported. o $startterm - Starting term point for the scan. The form in which the starting term is specified is given by parameter $type. The syntax this parameter is similar to the RPN query as described in yaz_search(3). It consists of zero or more @attr-operator specifica- tions, then followed by exactly one token. o $flags - This optional parameter specifies additional information to control the behaviour of the scan request. Three indexes are cur- rently read from the flags array: number (number of terms requested), position (preferred position of term) and stepSize (pre- ferred step size). RETURN VALUES
No value is returned. EXAMPLES
Example #1 PHP function that scans titles <?php function scan_titles($id, $startterm) { yaz_scan($id, "rpn", "@attr 1=4 " . $startterm); yaz_wait(); $errno = yaz_errno($id); if ($errno == 0) { $ar = yaz_scan_result($id, $options); echo 'Scan ok; '; foreach ($options as $key => $val) { echo "$key = $val "; } echo '<br /><table>'; while (list($key, list($k, $term, $tcount)) = each($ar)) { if (empty($k)) continue; echo "<tr><td>$term</td><td>$tcount</td></tr>"; } echo '</table>'; } else { echo "Scan failed. Error: " . yaz_error($id) . "<br />"; } } ?> PHP Documentation Group YAZ_SCAN(3)
