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.
Ce module est EXPERIMENTAL. Cela signifie que le comportement de ces fonctions, leurs noms et, concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS ! Soyez-en conscient, et utilisez ce module à vos risques et périls.
PECL/swish requires PHP 5.1.3 or newer.
Des informations sur l'installation de ces extensions PECL peuvent être trouvées dans le chapitre du manuel intitulé Installation des extensions PECL. D'autres informations comme les notes sur les nouvelles versions, les téléchargements, les sources des fichiers, les informations concernant les mainteneurs ainsi qu'un CHANGELOG, peuvent être trouvées ici : » http://pecl.php.net/package/swish.
The latest PECL/swish Win32 DLL can be downloaded here: » php_swish.dll.
Cette extension ne définit aucune directive de configuration.
Exemple 2682. 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";
}
?>
L'exemple ci-dessus va afficher quelque chose de similaire à :
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)
}
