Was ist effizienter? Verbinden mit der DB oder mit ein paar hundert Zeilen in einem Array?

Question

Ich versuche den Anrufcode und den Ländernamen meiner Besucher zu bekommen.

Zuvor hatte ich eine Verbindung mit dem DB die Telefonvorwahl und Ländernamen zu erhalten, die übereinstimmt wir von CloudFlare bekam, mit

$_SERVER["HTTP_CF_IPCOUNTRY"]; 

und

$country_code=$_SERVER["HTTP_CF_IPCOUNTRY"]; 
$stmt = $pdo->query('SELECT short_name, calling_code from country WHERE iso2 LIKE "'.$country_code.'"'); 
$country = $stmt->fetch(); 

Wenn jedoch Verkehr wird schwer, viele Verbindungen zur DB können problematisch sein. So definiert ich dieses Array:

und ich holen Sie einfach die Werte, die ich verwenden wollen:

$country_code=$_SERVER["HTTP_CF_IPCOUNTRY"]; 
$country=$countries[''.$country_code.'']; 

Damit entfällt die Notwendigkeit, an die DB zu verbinden und MYSQL verwenden.

Meine Frage ist, ist es schlecht, dieses Array mehrmals pro Sekunde geladen zu haben? Wird es die Leistung stark beeinträchtigen? Sollte ich einfach eine Verbindung zur DB haben wie früher?

Der Server verfügt über 16 GB RAM und 8 Kerne. Wir sprechen von 40 bis 50.000 Besuchen pro Tag.

Danke!

Answer 1

Erstens: $country=$countries[''.$country_code.'']; Dieses Array ist auf jeden Fall die bessere Wahl über eine Datenbank mit diesem $country=$countries[$country_code];

ersetzt werden. Jede Verbindung benötigt etwas Zeit und auf Arrays kann viel schneller zugegriffen werden.

Wenn Sie genau wissen wollen, wie der Unterschied ist, könnten Sie diese "Mini-Testsuite" verwenden, um den Laufzeitunterschied zu bestimmen.

$start1 = microtime(true); 

for($i = 0; $i < 10000; $i++) 
{ 
    //With database 
} 
$end1 = microtime(true); 

unset(); // The variables which might have been set the section above 

$start2 = microtime(true); 
for($i = 0; $i < 10000; $i++) 
{ 
    //code with array 
} 
$end2 = microtime(true); 

echo $end1-$start1."<br />"; 
echo $end2-$start2."<br />"; 

Ich hoffe, dass dies Ihnen hilft, wenn nicht bitte lass es mich wissen.
