unkown number of arguments

[Free WordPress Themes]

Hello,

I have to write a function where the number arguments is dynamic. Is the use of an array the only way to handle this?

example:

Code:

<?php
$string = "<a href=\"/{FOLDER}/script.php?lang={LANG}\">some text</a>";
$language = "nl";
$dyn_val = array("folder"=>"some_folder", "lang"=>$language); // this array can hold more or less elements

function test_overload($string, $dyn_val) {
foreach ($dyn_val as $key => $val) {
$string = str_replace("{".strtoupper($key)."}", $val, $string);
}
return $string;
}
echo test_overload($string, $dyn_val);
?>

This $dyn_val array is created by a query?

The fastest way to do this, is to make it without the use of str_replace. Something like

Code:

<?php
foreach ( $dyn_val as $v )
     echo "<a href=\"/".$v['folder']."/script.php?lang=".$v['lang']."\">some text</a>";

the array can hold a x number of arguments, also the string is different every time

If you need a faster way to achieve that the only thing you can do is get rid of the str_replace.

If you could tell me exactly what you want to do, maybe I can help you more.

I have actually all this messages in my classes:

Code:

<?php
$msg[33] = "Hello,\r\n\r\nthe new e-mail address must be validated, click the following link:\r\n".$host.$this->login_page."?id=".$this->id."&validate=".md5($this->user_pw)."&language=".$this->language."\r\n\r\nkind regards\r\n".$this->admin_name;
$msg[34] = "There is no e-mail address for validation.";
$msg[35] = "Hello,\r\n\r\nEnter your new password next, please click the following link to enter the form:\r\n".$host.$this->password_page."?id=".$this->id."&activate=".$this->user_pw."&language=".$this->language."\r\n\r\nkind regards\r\n".$this->admin_name;
$msg[36] = "Your request is processed and is pending for validation by the admin. \r\nYou will get an e-mail if it's done.";
$msg[37] = "Hello ".$this->user_full_name.",\r\n\r\nThe account is active and it's possible to login now.\r\n\r\nClick on this link to access the login page:\r\n".$host.$this->login_page."\r\n\r\nkind regards\r\n".$this->admin_name;
$msg[38] = "The confirmation password does not match the password. Please try again.";
$msg[39] = "A new user...";
$msg[40] = "There was a new user registration on ".date("Y-m-d").":\r\n\r\nClick here to enter the admin page:\r\n\r\n".$host.$this->admin_page."?login_id=".$this->id;
$msg[41] = "Validate your e-mail address..."; // subject in e-mail

I want to store them in a database for easier access and translations.
You seen a lot of them are very different. This function will act as kind of parser. The {VALUE} stored  in the database is easy to recognize by not programmers during translations

I see. I have made a different solution for that.

I keep the database for easier access and traslations, and each time there is a change on the database, a script creates the php file to include.

This way is still very fast, without loosing the flexibillity of the database.

yes I understand, but do you place all variables into the database field?

I use this form :

id -> message id
lang_id -> language id
message

And the file looks like :

$msg[$langid][$id] = $message

I use this form :

id -> message id
lang_id -> language id
message

And the file looks like :

$msg[$langid][$id] = $message

I think about the same, but I need to find a solution that non prgrammers (translations agencies) can handle this kind of text without breaking the code:

Code:

There was a new user registration on ".date("Y-m-d").":\r\n\r\nClick here to enter the admin page:\r\n\r\n".$host.$this->admin_page."?login_id=".$this->id;

That would be more difficult.

I guess you will have to create a script for translators that will strip those special characters/functions and show something like

Code:

, so you will do those str_replace in the input, or split messages that have functions.

thats the point where I cam back to my snippet, the question was more about to give arguments to this function
I read something about function overload, but this is not supported in PHP(4) right?

function overload? You mean class overload?

[Free WordPress Themes]

no function overloading:

check: http://www.google.com/search?hl=en&lr=&c2coff=1&q=php+function+overloading&btnG=Search

I think you can. Check this :

Code:

<?php
function foo()
{
   $numargs = func_num_args();
   echo "Number of arguments: $numargs<br />\n";
   if ($numargs >= 2) {
       echo "Second argument is: " . func_get_arg(1) . "<br />\n";
   }
   $arg_list = func_get_args();
   for ($i = 0; $i < $numargs; $i++) {
       echo "Argument $i is: " . $arg_list[$i] . "<br />\n";
   }
}

foo(1, 2, 3);
?>

... that wil say I can add so much as arguments to a function like I want? like:

Code:

<?php
function someFunction($var) {
  // my code
}

and call this function like:

Code:

<?php
someFunction("value for var", "some other value", 12, true, 45.89, "etc.");

EDIT: I think I repeated you answer

Didn't used functions like this before...

Yeah, but I am not sure if it works with simple functions, or only with class methods.

Make a test to be sure.

I will... thanks

I let you know if this works outside the class scope (By the way I will use this kind of function inside a class)
