1、在 Windows 10 中执行命令行,报错:Call to undefined function App/Console/Commands/posix_getpid()。如图1
PS E:/wwwroot/msi_main> php artisan migrate In ExportRecords.php line 65: Call to undefined function App/Console/Commands/posix_getpid()
2、参考网址:https://www.php.net/manual/zh/intro.posix.php 。此扩展在 Windows 平台上不可用。您也可以尝试使用 getmypid() 代替。如图2
3、posix_getpid — 返回当前进程 id。决定替换为:getmypid — 获取 PHP 进程的 ID。参考网址:https://www.php.net/getmypid。
4、编辑 /app/Console/Commands/ExportRecords.php 。将 posix_getpid 替换为 getmypid。
private function setLogPrefix() {
// $pid = posix_getpid();
$pid = getmypid();
$ppid = posix_getppid(); //获取父进程id
$this->log_prefix = "CommandExportRecords : pid:{$pid} : ppid:{$ppid} :";
return $this;
}
5、继续执行命令行,报错:Call to undefined function App/Console/Commands/posix_getppid()。
PS E:/wwwroot/msi_main> php artisan migrate In ExportRecords.php line 67: Call to undefined function App/Console/Commands/posix_getppid()
6、posix_getppid 在 Windows 上不起作用。这是一个替代方案。参考网址:https://www.php.net/manual/zh/function.posix-getppid 。判断是否是 Windows 系统,如果是,就使用替代方案。如图3
private function setLogPrefix() {
if(strncasecmp(PHP_OS, "win", 3) == 0) {
$pid = getmypid(); // child process ID
$ppid = shell_exec("wmic process where (processid=$pid) get parentprocessid");
$ppid = explode("/n", $ppid);
$ppid = intval($ppid[1]);
} else {
$pid = posix_getpid();
$ppid = posix_getppid(); //获取父进程id
}
$this->log_prefix = "CommandExportRecords : pid:{$pid} : ppid:{$ppid} :";
return $this;
}
7、继续执行命令行,未再报错。如图4
PS E:/wwwroot/msi_main> php artisan migrate Migration table created successfully.
