PHP中json_encode、json_decode与serialize、unserialize
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:
<?php $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 < 10000; $i ++) { json_encode( $target ); } $etime = microtime(true); echo "json_encode : " . ( $etime - $stime ) . " " ; //---------------------------------- $stime = microtime(true); for ( $i = 0; $i < 10000; $i ++) { json_decode( $json ); } $etime = microtime(true); echo "json_decode : " . ( $etime - $stime ) . " " ; //---------------------------------- $stime = microtime(true); for ( $i = 0; $i < 10000; $i ++) { serialize( $target ); } $etime = microtime(true); echo "serialize : " . ( $etime - $stime ) . " " ; //---------------------------------- $stime = microtime(true); for ( $i = 0; $i < 10000; $i ++) { unserialize( $seri ); //开源代码phpfensi测试数据 } $etime = microtime(true); echo "unserialize : " . ( $etime - $stime ) . " " ; echo 'DONE.' ; ?>查看更多关于PHP中json_encode、json_decode与serialize、unserialize的详细内容...
