PHP脚本不会在后台运行 [英] PHP script won't run in the background

问题描述

我正在尝试在后台运行php CLI脚本，但它不会运行-它的状态为Stopped SIGTOU(试图写输出)-以下是详细信息

I am trying to run a php CLI script in the background and it just won't run - it has a status of Stopped SIGTOU (Trying to write output) - Here are the details

• Mac OS X Lion 10.7.2
• 带有Suhosin-Patch(cli)的PHP 5.3.6(内置:2011年9月8日19:34:00)

我创建了一个基本脚本test.php

I created a basic script test.php

<?php echo 'Hello world'.PHP_EOL; ?>

以下是各种测试的结果:-

Here are the results of various tests:-

• php -f test.php(将显示Hello World)
• php -f test.php >test.log 2>&1(您好，世界进入了test.log)
• php -f test.php >test.log 2>&1 & ---我得到了[1]+ Stopped(SIGTTOU) php -f test.php > test.log 2>&1-只是坐在那里，什么也没记录，但是lsof显示日志文件已打开

• php -f test.php (Hello world gets displayed)
• php -f test.php >test.log 2>&1 (Hello world gets put into test.log)
• php -f test.php >test.log 2>&1 & --- I get [1]+ Stopped(SIGTTOU) php -f test.php > test.log 2>&1 -- and the job just sits there doing nothing nothing gets logged however lsof shows the log file is open

这与PHP有关吗?类似的shell脚本在后台执行也没有问题.

It is something to do with PHP? A similar shell script gets executed no problems in the background.

推荐答案

如果在您的php构建中启用了readline，则只需传递/dev/null作为输入即可.

If readline is enabled in your build of php, simply pass /dev/null as the input.

在上面的示例中，应该是:

In your example above, it would be:

php -f test.php </dev/null >test.log 2>&1
