PHP read data from Memcache and then bulk write to MySQL _php tips

This article is an example of how PHP reads data from memcache and then writes to MySQL in batches. Share to everyone for your reference. The specific analysis is as follows:

Use Memcache to ease PHP and database pressure The following code is to solve the high load database write bottleneck problem, encountered the most practical: Write IP PV UV, the user reached tens of thousands of per minute traffic, to record the data, real-time write to the database must run.

With the following technology can be resolved, as well as user registration, the same time broken, a large number of user registration, can be cached after a one-time write to the database, the code is as follows:

Copy Code code as follows:

Public Function Cldata () {
$memcache _obj = new Memcache;
$memcache _obj->connect (' 127.0.0.1 ', ' 11211 ');
$all _items = $memcache _obj->getextendedstats (' items ');
foreach ($all _items as $option => $vall) {
if (Isset ($all _items[$option] [' items ']) {
$items = $all _items[$option] [' Items '];
foreach ($items as $number => $item) {
$str = $memcache _obj->getextendedstats (' Cachedump ', $number, 0);
$line = $str [$option];
if (Is_array ($line) && count ($line) > 0) {
foreach ($line as $key => $value) {
$keys [] = $key;
}
}
}
}
}

Dump (count ($keys));//Get to Key
if (count ($keys) >50) {//number of data bars to write
$end = 50;
}else{
$end =count ($keys);
}

for ($i =0; $i <= $end; $i + +) {
if (!strstr ($keys [$i], ' datadb ')) continue;
$KSV = Str_replace (' datadb ', ', ', $keys [$i]);

/* $logdata = unserialize (S (' login '. $ksv))//Login Write
if (Is_array ($logdata)) {
$this->addsuidinlogin ($logdata [0], $logdata [1], $logdata [2],1);
}   */

/* $sdata = unserialize (S (' Regadd '. $ksv));//Register Write
if (Is_array ($sdata)) {
$this->baiduad ($sdata [0], $sdata [1], $sdata [2], $sdata [3], $sdata [4],1];
}
*/
$regdata = Unserialize (S (' datadb '. $ksv));
$ress []= $regdata;
S (' datadb '. $KSV, NULL);

}
$ADDB = M ()->db (66,c (' Db_web_ad '))//Bulk Write AddAll
$addb->table (' Mj_ad_count ')->addall ($ress);
Echo M ()->getlastsql ();
}
