#5913 — variable replacement in string

Hi,

I am still searching a function in PHP to execute variable replacement in strings.
Other languages do have this, but for PHP I can only find sprintf() and string replace.

I have

$t = ' - solved - ';
$msg = 'The problem is $t';

I want now:

echo fxx($msg);

print out  "The problem is  - solved - ".

Please don't tell me about $msg = "The problem is $t"; just think of $msg like a
template read from a file.

/Str.

what is wrong with printf("the problem is %s \n",$t);


or

echo ("the problem is".$t);

relating %s to $t is extra work.

or

echo 'the problem is ', $t;

be sure I can do it in code. In Tcl, interactive session:

strobel@s114-intel:~> tclsh
% set t " - solved - "
 - solved -
% set msg {the problem is $t}
the problem is $t
% puts $msg
the problem is $t
% puts [subst $msg]
the problem is  - solved -
%

strtr() ?

You could do something like this:

$template = 'Your name is %given_name% %family_name%';

echo strtr($template, array(
    '%given_name%' => 'John',
    '%family_name%' => 'Doe',
    ));

if you want to program in tcl., i suggest you use tcl.

your example
$t = ' - solved - ';
$msg = 'The problem is $t';

should be
$t = ' - solved - ';
$msg = 'The problem is'.$t;
echo($msg);

You cannot miss something you do not know it exists.

Of course you can. Don't be silly.

I've missed loads of things that I didnt know about.

Like the flight to Chicago. I've missed every single flight to chicago, 
ever. Most before I even knew there was one. :-)

Hardly,. His lord High Stuckupness has been in my killfile a LONG time, 
as he never says anything worth reading - as evinced by this 
particularly puerile offering.

TESTED:

#!/usr/bin/php
<?

    $t = "SOLVED";
    $template = 'The problem is $t';
    
    print fxx($template);
    
    function fxx($string){
        if (preg_match_all("/\\$([a-z_A-Z]+)/i", $string, $matches)) {
            foreach($matches[1] as $m) {
                global $$m;
            }
            $string = preg_replace(
                "/\\$([a-zA-Z_]+)/sei",
                "\${\\1}",
                $string
            );
        }
        return $string;
    }
?>

Of course, having posted that, I'd still use caution with scopes and 
globilzation of variables, since this function may be called inside 
another function which hasn't globalized $t, so I would still 
recommend to send along a variables of values:


#!/usr/bin/php
<?

    $values["t"] = "SOLVED";
    $template = 'The problem is $t';
    
    print fxx($template, $values);
    
    function fxx($string, $values){
        $string = preg_replace(
            "/\\$([a-zA-Z_]+)/sei",
            "\$values['\\1']",
            $string
        );
        return $string;
    }
?>

And using single quotes when creating the template is important as 
well, since we're using PHP-style variables. If you have your own 
variable denotation, you don't have to think about that at all (see my 
earlier parserxml() function)

There's also preg_replace(), but that's a bit of overkill for something 
so simple.

str_replace() works fine, especially since both the search and replace 
parameters can be arrays.  But when using message templates, I don't use 
variable names - it ties the template tightly to the code.

Rather, I use templates like:

$t = ' - solved - ';
$template = 'The problem is %PROB_STAT%';
echo str_replace('%PROB_STAT%', $t, $template);

Or, if you had the possibility of more than one string to substitute:

$search = array('$PROB_STAT%');
$replace = array($t);
echo str_replace('%PROB_STAT%', $t, $template);

Your method requires the template know that $t is the value in the 
program, and requires the program to ensure $t is defined properly in 
this scope.  Neither is a good idea.

I see the problem of the undefined $t.

Think of my method as "do what double quotes do".

It may well not exist, maybe I file a feature request.

No, you miss the point.  You are also now closely coupling your template 
to your code.  Such coupling is not good - it severely limits possibilities.

For instance, let's say you want to use the same message another place 
in your code - but you've already used $t.  Do you rewrite the entire 
routine?  Or maybe you want to use your templates somewhere completely 
different.

Tight coupling is bad because it creates more (and often unnecessary) 
dependencies.  Loose coupling limits dependencies, and fewer 
dependencies means fewer errors crop into the code.

How about:
$msg = 'The problem is {$t}';

And the next step? How do you print that the problem is solved?

But maybe you could do a regex replace with this...

/Str.
