在安静模式下运行PHP是什么意思? [英] What does it mean to run PHP in quiet mode?

问题描述

您可以使用-q命令行开关运行PHP.手册只说:

You can run PHP with the -q command line switch. The manual only say:

安静模式.禁止HTTP标头 输出(仅CGI).

Quiet-mode. Suppress HTTP header output (CGI only).

实际上，这实际上意味着什么?

What does that actually mean in practical terms?

推荐答案

这仅涉及针对CGI SAPI构建的PHP解释器.此版本在实际输出之前会发送一些基本的HTTP标头:

This only concerns the PHP interpreter built against the CGI SAPI. This version sends a few basic HTTP headers before any actual output:

X-Powered-By: PHP/5.3.3-1ubuntu9.3
Content-type: text/html

"(echo) What I actually wanted to have"

因此，基本上-q命令行标志可防止将任何header()写入标准输出.

So basically the -q commandline flag prevents any header() from being written to stdout.

目的是使用php-cgi二进制文件代替控制台脚本的php CLI变体.通常，您会在此类脚本中看到以下shebang来强制php-cgi表现为-cli版本:

The purpose is to use the php-cgi binary in lieu of the php CLI variant for console scripts. Usually you see following shebang in such scripts to force php-cgi to behave like the -cli version:

#!/usr/bin/php-cgi -qC
