position
Zero-based position number. Cannot be less than zero.
Returns new position value on success.
Throws SwishException on error.
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
