swoole异步读取文件、写入文件

读取写入上限内容4M,如果不满足需求,需要自行到配置文件修改

异步读取文件:swoole_async_readfile()

/**读取文件**/ //sleep(3); $res = swoole_async_readfile(__DIR__."/test.txt",function($filename,$fileContent){ echo "filename:.$filename".PHP_EOL; echo "fileContent".PHP_EOL; echo $fileContent; }); sleep(2); echo "Is me The First?"; var_dump($res);

运行结果:

Is me The First?bool(true) filename:./swoole/project/swoole1/async/test.txt fileContent This a file Test This is The 2ed line.

异步写入文件:swoole_async_writefile()

$content = date("Y-m-d H:i:s",time()).PHP_EOL; $res = swoole_async_writefile(__DIR__."/log.txt",$content,function($filename){ echo 'ok'.PHP_EOL; },FILE_APPEND); echo 'is my 1st?'.PHP_EOL; var_dump($res); echo $content; echo __DIR__."log.txt";

运行结果:

is my 1st? bool(true) 2018-10-25 10:14:51 /swoole/project/swoole1/asynclog.txtok

小总结:异步函数部分会在本次运行文件最后执行,但是运行的结果(成功或者失败)可以提前拿到。

异步写入文件,应用到某些关键性的操作,记录log日志,非常高效实用哦!
