This article mainly introduces the realization of multiple processes writing a file at the same time in PHP. It has a certain reference value. Now I share it with you. Friends in need can refer to it
<?php function writefile( $filename, $data ){ $fp = fopen( $filepath, 'a'); / /以追加的方式打开文件,返回的是指针 do{ usleep(100 ); //暂停执行程序,参数是以微秒为单位的 }while( !flock( $fp, LOCK_EX ) );//以独享写入的方式锁定文件,成功则返回TRUE,否则FALSE } $res = fwrite( $fp, $data."/n");// 以追加的方式写入数据到打开的文件 flock( $fp, LOCK_UN );//解锁,以让别的进程进行锁定 fcloce( $fp );//关闭打开的文件指针 return $res;//返回写入结果 ?>
