text replacements help

I have this code below...but I also want to have multiple replacements. Like {userid} for example. How can I add multiple replacements to this line of code?

Code:

$test = @str_replace("{username}", $vbulletin->userinfo['username'], $message);

I tried doing a

Code:

$test = @str_replace("{username}", $vbulletin->userinfo['username'], $message);

$test = @str_replace("{userid}", $vbulletin->userinfo['userid'], $message);

but it didnt work, and still only outputted the userid and not both

Because you use $message in the second source string. Use $test there.

PHP Code:


		
			
$test = @str_replace("{username}", $vbulletin->userinfo['username'], $message);
$test = @str_replace("{userid}", $vbulletin->userinfo['userid'], $test);

$message remains the same after the first replacement and $test gets overwritten with the second replacement.

and what if I wanna add a third and fourth, how does the theory apply? New variables each time? Because I wanna be able to use multiple replacements like username, userid, all in the same variable...from the text field I made up in the product options, I made.

You've gotta be able to do it all in one line...(peice of code)

No, I'll try to explain better.

The main text is held in the variable $message.
We create a new variable called $test, which is equal to $message, just with the replaced words. So we want to replace more words, we'll use the $test variable as third argument in str_replace() as $test contains the variables we replaced first. We want these plus the ones we're gonna replace now.

Do you understand? $message remains untouched as we assign the NEW text to a different variable. So use this new variable for the other replacements too.

PHP Code:


		
			


$test = @str_replace("{username}", $vbulletin->userinfo['username'], $message);

$test = @str_replace("{userid}", $vbulletin->userinfo['userid'], $test);

$test = @str_replace("{blah}", $vbulletin->userinfo['userid'], $test);

$test = @str_replace("{blah2}", $vbulletin->userinfo['userid'], $test);



//...

Another option is using arrays as arguments.

PHP Code:


		
			
$replacements = array(

   '{username}' => $vbulletin->userinfo['username'],

   '{userid}'   => $vbulletin->userinfo['userid'],

   '{blah}'     => $vbulletin->userinfo['blah']

   // ...

);



$test = str_replace(array_keys($replacements), array_values($replacements), $message);

Nico, that makes alot more sense, I really appreciate the explaination and code examples. It works! Thanks again. ;)

One more issue...how can I retrieve the logged in users usergroup title? The below wont work at all...nor will other combinations I've tried...

PHP Code:


		
			
$test = @str_replace("{blah2}", $vbulletin->usergroupcache['title'], $test);

vBulletin has a built-in function to do this. Just use {1}, {2}, and so-forth as the replacement.

Well, what I have is working fine...just cant grab the usergroups title, which may be a seperate issue. Maybe I'll have to do a query or something
