范例
Example #1 Basic SwishResults::seekResult() example
<?php
try {
$swish = new Swish("index.swish-e");
$search = $swish->prepare();
$results = $search->execute("lost");
var_dump($results->seekResult(0)); //this will succeed
var_dump($results->seekResult(100)); //this will fail
} catch (SwishException $e) {
echo "Error: ", $e->getMessage(), "\n";
}
?>
以上例程的输出类似于:
int(0) Error: No more results
