The swish extension provides the bindings for Swish-e API. Swish-e stands for "Simple Web Indexing System for Humans - Enhanced" and is an open source system for indexing and search. Swish-e itself is licensed under GPL license, but uses a clause that allows applications to link against the library if every copy of the combined work is accompanied by the URL to Swish-e source code. Here it is: » http://swish-e.org.
Toto rozšírenie je EXPERIMENTÁLNE. Správanie tohto rozšírenia -- vrátane názvov jeho funkcií a hocičoho iného zdokumentovaného o tomto rozšírení -- sa može zmeniť bez povšimnutia v budúcom vydaní PHP. Používajte toto rozšírenie na svoje vlastné riziko.
PECL/swish requires PHP 5.1.3 or newer.
Dodatočné informácie ako sú nové vydania, downloady, zdrojové súbory, informácie od spracovávateľa, a CHANGELOG, je možné nájsť tu: » http://pecl.php.net/package/swish.
The latest PECL/swish Win32 DLL can be downloaded here: » php_swish.dll.
Toto rozšírenie nemá žiadne konfiguračné direktívy definované v php.ini.
Example#1 Basic search query
<?php
try {
$swish = new Swish("index.swish-e");
$results = $swish->query("test OR text");
echo "Found ", $results->hits, " results\n";
while ($result = $results->nextResult()) {
var_dump($result);
break; //break after the first result
}
} catch (SwishException $e) {
echo "Error: ", $e->getMessage(), "\n";
}
?>
Výstup horeuvedeného príkladu bude niečo podobné tomuto:
Found 9 results object(SwishResult)#3 (8) { ["swishreccount"]=> int(1) ["swishrank"]=> int(1000) ["swishfilenum"]=> int(10) ["swishdbfile"]=> string(13) "index.swish-e" ["swishdocpath"]=> string(23) "README.SUBMITTING_PATCH" ["swishtitle"]=> NULL ["swishdocsize"]=> int(4557) ["swishlastmodified"]=> int(1072136752) }
Konštanty uvedené nižšie sú definované týmto rozšírením a budú dostupné iba keď rozšírenie bolo buď kompilované do PHP alebo dynamicky načítané za behu (runtime).
