Using PHP to execute cmd commands
提问by Wern Ancheta
How do I properly execute commands in the command line using php? For example I'm using the command below in the command line to convert a docx file into a pdf file:
如何使用 php 在命令行中正确执行命令？例如，我在命令行中使用以下命令将 docx 文件转换为 pdf 文件：
pdfcreator.exe /PF"D:\Documents\sample.docx
Now using PHP code I want to be able to execute the same command but nothing seems to be happening:
现在使用 PHP 代码，我希望能够执行相同的命令，但似乎什么也没发生：
<?php
shell_exec('pdfcreator.exe /PF"D:\Documents\sample.docx"');
?>
Is this possible in PHP?If yes, how do I do it?

Don't forget to escape your command with escapeshellcmd(). This will prevent you from having to use ugly backslashes and escape characters.
不要忘记使用escapeshellcmd()转义您的命令。这将防止您不得不使用丑陋的反斜杠和转义字符。
There are also other alternatives which may work:
还有其他可能有效的替代方法：
`command` // back ticks drop you out of PHP mode into shell
exec('command', $output); // exec will allow you to capture the return of a command as reference
shell_exec('command'); // will return the output to a variable
system(); //as seen above.
Also, make sure your .exe is included within your $PATH variable. If not, include the full path for the command.
另外，请确保您的 .exe 包含在您的 $PATH 变量中。如果没有，请包含命令的完整路径。
