json_encode和json_decode的效率并没有比serialize和unserialize的效率高,在反序列化的时候性能相差两倍左右,PHP 5.3执行效率比PHP 5.2略有提升。

 代码如下 复制代码


$target = array (
'name' => '全能头盔',
'quality' => 'Blue',
'ti_id' => 21302,
'is_bind' => 1,
'demand_conditions' =>
array (
'HeroLevel' => 1,
),
'quality_attr_sign' =>
array (
'HeroStrength' => 8,
'HeroAgility' => 8,
'HeroIntelligence' => 8,
),
);
$json = json_encode($target);
$seri = serialize($target);
echo "json : " . strlen($json) . " ";
echo "serialize : " . strlen($seri) . " ";
$stime = microtime(true);
for ($i = 0; $i {
json_encode($target);
}
$etime = microtime(true);
echo "json_encode : " . ($etime - $stime) . " ";
//----------------------------------
$stime = microtime(true);
for ($i = 0; $i {
json_decode($json);
}
$etime = microtime(true);
echo "json_decode : " . ($etime - $stime) . " ";
//----------------------------------
$stime = microtime(true);
for ($i = 0; $i {
serialize($target);
}
$etime = microtime(true);
echo "serialize : " . ($etime - $stime) . " ";
//----------------------------------
$stime = microtime(true);
for ($i = 0; $i {
unserialize($seri);
}
$etime = microtime(true);
echo "unserialize : " . ($etime - $stime) . " ";
echo 'DONE.';
?>
