Hey Harvey,

My php skills are still towards the "newbie" side.

But... you can post this prob on tek-tips.com. It's my
secret weapon whenever I have a coding question.
You should get an answer within a day or so.

Hope this helps.

Best,

I'd just do it using the string replace function:

$rawString = "Hello {abc}, goodbye {def}";

$newString = str_replace("{abc}", "Harvey", $rawString);
$newString = str_replace("{def}", "Sam", $newString);

echo $newString;


....gives you:

Hello Harvey, goodbye Sam


Quick and easy, just the way I like my code

cheers
Sam

Learn regular expressions.

And then you will be able to replace patterns , such as "{XXXXXX}".

Is this for a membership site login and logout???

What I do to learn these kinda things is by studying code from the CMS programs (wordpress,joomla, etc.)

Then I implement it.

Hope this helps...

Then what is the primary purpose...???

I spend the hours it takes to learn the simplest things....

I don't rely on others information...

Agreed...

take a look at this....

PHP: strtok - Manual

I stole this from some open source code. It may give you and idea of how to proceed.

function fill($template, $values) {

if (sizeof($values) != 0) {
// go through all the values
for(reset($values); $key = key($values); next($values)) {
$template = str_replace("{$key}",$values[$key],$template);
}
}

// remove non matched template-tags
return preg_replace('/{[a-zA-Z]+}/','',$template);
}

OK. Not a PHP programmer, but I can manage.
Here is the code stolen from above.
===========================
$s='Hello {abc}, goodbye {def}';

echo preg_replace_callback('/\{([^{}]+)\}/',whatever,$s);

function whatever($what)
{
return strtoupper($what[1]);
}

==============================

Wht's happening:

preg_replace_callback = the first funny string basically says match everything in {} that is not a curly bracket that gets your ABC or DEF

whatever is the name of a function

$s is the string you are looking through "Hello {abc}, goodbye {def}" in the example

So in the function "whatever" this code returns the uppercase version of the string that was matched (abc or def converts to ABC or DEF)

so you would replace the functionality in there with something like

$lookup = strtoupper($what[1]); //Assumes you want a case insensitive lookup
//Use $lookup to find the value you want, such as using a map variable or looking the value up in the DB (which would be very slow if you do it repeatedly).


===========================
$s='Hello {abc}, goodbye {def}';

echo preg_replace_callback('/\{([^{}]+)\}/',replace_token_with,$s);

function replace_token_with($what)
{
$lookup = strtoupper($what[1]);
return get_value_of($lookup);
}

==============================

Needs a login
So you have wanted something like

function replace_token_with($what)
{

return "http://www.example.com/decodeurlscript.php?u=" + urlencode($what[1]);
}

I've never found doing in place substitutions inside PDF files to work well, especially since it requires uncompressed PDFs.

How do you do it? Just a simple replace, or modify a base (eg postscript) fiel and generate from that?
