Command-Line Help

[DomenicF]

Hello,

 

I have a script that takes two parameters that I retrieve with $argv. But, I see a lot of scripts in other languages that have "--help" and "-h" in them and other options/flags like that, and I'm curious to find out the correct way to add these to my script. Any suggestions?

I've written a couple command-line-parsing functions, none of which I have on hand to demonstrate. If you want to write one it depends how much support you need from it (because there are a few possible styles to choose from - I want to say GNU, POSIX, and BSD?).

 

At a minimum all you need is

if (in_array("-h", $argv) || in_array("--help", $argv)) {

Thanks for your response. I have this code right now, but nothing has changed with the output.

 

if (!in_array("-h", $argv) || !in_array("--help", $argv)) {
// stuff here
}
else {
	echo "Help!";
}

Take a look at getopt, no point in rolling your own.

I took a look into that, and tried putting it into practice, but could not figure it out. The examples they give aren't very helpful to be honest, would you mind writing an example for me? I would really appreciate it.

Ooh, they greatly improved it in 5.3. I'll have to check it out again.

I'm not sure I could explain it any simpler than the manual. Where exactly are you stuck?

You're right, I just wasn't fully understanding the function before. I tried a few things and got it working. Appreciate the link!
