decimal number ??

MichaelHe

Probably a very simple question.

In a setup file I have writen $var='1.25';

In another file i write require("Setup.php");
$message='sometekst $var and some more';

But when I email the $message it doesn't write the $var...
I guess it's because it's a decimal number, but how do I do it ??

The fact that it is a number should not matter. However, the code sample you showed us will not work because variables are not interpolated within single-quoted strings. You'll need to change it to one of the following options:

$message = "sometekst $var and more";
// . . . or . . .
$message = 'sometekst ' . $var . ' and more';
// . . . or . . .
$message = sprintf('sometekst %s and some more', $var);

Oh sorry :o)
I have written $message="sometekst $var and some more";

But the number is just not written in the email... But if I change it to $var='1'; in my setup file it writes 1 in the email.
So it's only when it's 1.00 it doesn't work

When it is "1.00", does nothing get output at all for the variable, or just the "1"?

Nothing gets outputed

And one little thing... How do I remove the first caracter of a variable ?
Some tekstlines are put together with a - between them, but it also puts a - in the beginning of the string.. like this -something-something-something
So how do I remove the first - ?

There is no reason that the value being a number with a decimal fraction part should stop it from being output in the manner you have described. Something else is going on in your code that we are not seeing.

There are many ways you could do that (see string functions if you want to investigate them all). Here's one way:

$string = ltrim($string, '-');

Is the instance where you attempt to use $var again inside a function? If so, you're experiencing a variable scope problem. Try a very simple example:

config.php

$var = 'test';

page.php

require_once 'config.php';
function foo() {
    $test = (isset($var) ? 'set' : 'not set');
    echo '$var is: ' . $test;
    if($test == 'not set') {
        global $var;
        echo "<br>\nusing the variable from the global scope: $var";
    }
}
echo $var;
echo "<br>\n";
foo();

That should illustrate what's (possibly) happening to you.
