Basic VarnishAdmin usage

The example illustrates a simple usage of the ban functionality

示例 #1 Ban an URL

<?php

$args = array(
    VARNISH_CONFIG_HOST    => "::1",
    VARNISH_CONFIG_PORT    => 6082,
    VARNISH_CONFIG_SECRET  => "5174826b-8595-4958-aa7a-0609632ad7ca",
    VARNISH_CONFIG_TIMEOUT => 300,
);

$va = new VarnishAdmin($args);

try {
    if(!$va->connect()) {
        throw new VarnishException("Connection failed\n");
    }   
} catch (VarnishException $e) {
    echo $e->getMessage();
    exit(3);
}

try {
    if(!$va->auth()) {
        throw new VarnishException("Auth failed\n");
    }   
} catch (VarnishException $e) {
    echo $e->getMessage();
    exit(3);
}

try {
    $status = $va->ban('req.url ~ "^/$"');
    if (VARNISH_STATUS_OK != $status) {
        throw new VarnishException("Ban method returned $status status\n");
    }
} catch (VarnishException $e) {
    echo $e->getMessage();
    exit(3);
}

exit(0);

?>

Basic VarnishStat usage

The example illustrates getting varnish statistic snapshot from shared memory

示例 #1 Get statistic snapshot

<?php

$vs = new VarnishStat;

try {
    $data = $vs->getSnapshot();
} catch (VarnishException $e) {
    echo $e->getMessage();
    exit(3);
}

exit(0);
?>

Basic VarnishLog usage

The example illustrates reading varnish log lines from shared memory

示例 #1 Read varnish shared memory log

<?php

$vl = new VarnishLog;
while(1) {
    $line = $vl->getLine();
    printf("%s %d %s", VarnishLog::getTagName($line['tag'], $line['id'],
    $line['data']);
}

exit(0);
?>
