Using PHP to execute cmd commands

Posted by: admin July 12, 2020 Leave a comment


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:

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:

shell_exec('pdfcreator.exe /PF"D:\Documents\sample.docx"');

Is this possible in PHP?If yes, how do I do it?

How to&Answers:
system("c:\path\to\pdfcreator.exe /PF\"D:\Documents\sample.docx""); 

try this.


Don’t forget to escape your command with escapeshellcmd(). This will prevent you from having to use ugly backslashes and escape characters.

There are also other alternatives which may work:

`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.
