HomeBackend DevelopmentPHP Tutorial求大神帮忙看看,php socket的问题

	$appenStr = $buf = '';	$time = time();	for($i=0;$i<100;$i++){		$buf = socket_read($msgsock, 8192);		if(time() - $time > 5){			break;		}		if($buf){			$appenStr .= $buf;		}else{			break;		}	}		echo $appenStr;

网上看了很多资料,是socket_read这个函数阻塞了,导致的客户端程序一直假死状态,一直等待上面代码的结果 返回。
但是我这样就能取出来数据了。
$buf = socket_read($msgsock, 8192);	$buf .= socket_read($msgsock, 8192);	$buf .= socket_read($msgsock, 8192);
可是总不能算好字节数去取吧。还有下面的代码我也试过了,还是假死,一直在加载中。
$appenStr = $out = '';	$start_time = time();	do{		if (false === ($out = socket_read($msgsock, 8192)))		{			echo ("SOCKET_READ_ERROR: " . socket_strerror(socket_last_error($msgsock)));			$str = "";			break;		}		if (time() - $start_time > 1)		{			echo ("SOCKET_READ_ERROR: Timeout!!!");			$str = "";			break;		}		$appenStr .= $out;	} while ($out != "");

求大神指导


回复讨论(解决方案)

如果在输入流已经读空的情况下,你再去读,就会出现死锁(因为再也读不到东西了)
所以准确的判断是否读空是很重要的
    if( trim($buf )){
        $appenStr .= $buf;
    }else{
        break;
    }

谢谢。可我试了下,还是有那问题

来人啊,求大神帮忙啊

找到答案了,哈

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
