Major new features

Redis/PDO/MySQLi support

From4.1.0Version began to support the rightPHPNativeRedis、PDO、MySQLiThe support of coordination.

Swoole\Runtime::enableCoroutine();
 
 go(function () {
 $redis = new redis;
 $retval = $redis->connect("127.0.0.1", 6379);
 var_dump($retval, $redis->getLastError());
 var_dump($redis->get("key"));
 var_dump($redis->set("key", "value"));
 $redis->close();
 });

Concorde tracking

The new version adds two methods to track coordinated operation.

• Coroutine::listCoroutines()It can traverse all current synergetic processes.
• Coroutine::getBackTrace($cid)A function call stack that can obtain a certain coordination

function test1() {
 test2();
 }
 
 function test2() {
 while(true) {
 co::sleep(10);
 echo __FUNCTION__." \n";
 }
 }
 
 $cid = go(function () {
 test1();
 });
 
 go(function () use ($cid) {
 while(true) {
 echo "BackTrace[$cid]:\n-----------------------------------------------\n";
 //Return array, need self-print format
 var_dump(co::getBackTrace($cid))."\n";
 co::sleep(3);
 }
 });
