[SOLVED] Passing a variable through a function?

[N1CK3RS0N]

Hello,

 

I was wondering if its possible to pass a variable through a function?

 

Something like this:

 

<?php

function cows($noise) {
if ($noise == moo) {
	$say = "Hi Mr. Cow";
} else {
	$say = "Your no Cow fool!";
}
}

cows('moo');

echo $say;

?>

 

The 'Echo $say;' does nothing.

you need to pass by reference. a variable created inside a function is localized to that function.

Hmm. That confuses me. Is there no other way? Don't think that will work for what I'm trying to do.

or declare a global variable. what are you trying to do?

<?php

function cows($noise) {
   global $say;
   if ($noise == moo) {
      $say = "Hi Mr. Cow";
   } else {
      $say = "Your no Cow fool!";
   }
}

cows('moo');

echo $say;

?>

 

That would work, but serves as poor-programming.

I have a number of things going to be using a function. Its checking file permissions. If every file permission meets requirements then the submit button on the form works, otherwise it is disabled.

 

<?php

$pass = "true";

function check_perms($file, $perm) {
if (substr(decoct(fileperms("$file")),2) == $perm) {
	return "<div class=\"container\" style=\"color: #008000; font-weight:bold;\">Pass</div>";
} else {
	$pass = "false";
	return "<div class=\"container\" style=\"color: #D00000; font-weight:bold;\">Fail</div>";
}
}

$backups = check_perms('../backups/', '777');
$downloads_uploads = check_perms('../downloads/uploads/', '777');
$images_uploads = check_perms('../images/uploads/', '777');
$images_banners = check_perms('../images/banners/', '777');
$include_config = check_perms('../includes/config.php', '666');
$languages = check_perms('../languages/', '777');
$modules = check_perms('../modules/', '777');
$templates = check_perms('../templates/', '777');

if ($pass == 'true') {
$input_button = "<input type=\"submit\" id=\"submit\" value=\"{$LANG.submit_button}"\ name=\"submit\" />";
} else {
$input_button = "<input type=\"submit\" id=\"submit\" value=\"{$LANG.submit_button}"\ name=\"submit\" disabled=\"disabled\" />";
}

?>

 <?php

$pass = "true";

function check_perms($file, $perm,&$pass) {
if (substr(decoct(fileperms("$file")),2) == $perm) {
	return "<div class=\"container\" style=\"color: #008000; font-weight:bold;\">Pass</div>";
} else {
	$pass = "false";
	return "<div class=\"container\" style=\"color: #D00000; font-weight:bold;\">Fail</div>";
}
}

$backups = check_perms('../backups/', '777',$pass);
$downloads_uploads = check_perms('../downloads/uploads/', '777'$pass);
$images_uploads = check_perms('../images/uploads/', '777',$pass);
$images_banners = check_perms('../images/banners/', '777',$pass);
$include_config = check_perms('../includes/config.php', '666',$pass);
$languages = check_perms('../languages/', '777',$pass);
$modules = check_perms('../modules/', '777',$pass);
$templates = check_perms('../templates/', '777',$pass);

if ($pass == 'true') {
$input_button = "<input type=\"submit\" id=\"submit\" value=\"{$LANG.submit_button}" name="submit\" />";
} else {
$input_button = "<input type=\"submit\" id=\"submit\" value=\"{$LANG.submit_button}" name="submit\" disabled=\"disabled\" />";
}

?>

Awesome Schilly

 

I owe ya 1

 

And I typed that up in 2 seconds Goldeneye, I realize I missed the "" in the if condition.

i believe Goldeneye meant declaring a global.
