adding string variables

[thefollower]

I have a line where by two variables have numbers but i can't put them together, how is this done?

 

$Multiply = 0.000

$Input = 45;

 

Then i want them two, to be put together so one variable will show the string as:

0.00045

 

Im not looking for maths here just a way to string them together..

For starters, they are not strings.

[tommyboy123x]

moreover, that just equals zero.  To get .00045, you need to multiply 45 x .00001

 

 

if you just want to put the two variables together, just make sure there arent two decimal places either.

 

$answer = $multiply.$input;

 

also make sure your variables are all the same case, i.e. $Multiply isn't the same as $multiply

[trq]

moreover, that just equals zero.

 

Actually, it would equal 45.

 

If they where string and you wanted to concatinate them....

 

<?php

  $Multiply = '0.000';
  $Input = '45';
  echo $Multiply.$Input;

?>

php defaults to numeric? If so that is pain in the butt!!!

 

tommyboy.. unfortionutely your idea didn't quite produce what i was hoping for..

 

$Multiply = 0.00;
$Input = 6;

Echo $Answer = $Multiply.$Input;

 

The result gave : 06

Instead of 0.006

 

Hope you can help.

<?php

  $Multiply = '0.000';
  $Input = '45';
  echo $Multiply.$Input;

?>

 

How did you get that to work ? it just shows 45 on my screen :S rather than 0.00045

[thefollower]

settype($Multiply, "string");
settype($StrengthInput, "string");
$Multiply = 0.00;
$StrengthInput = 6;

Echo $Answer = $Multiply.$StrengthInput;

 

This echos 06 also and if i put set type after the $variables it still shows 06 rather than 0.006

 

[kenrbnsn]

Try something like this:

<?php
$Multiply = number_format(0,2);
echo $Multiply."<br>";
$StrengthInput = 6;
$Answer = $Multiply.$StrengthInput;
echo $Answer."<br>";
?>

It defaults to the type of value the variable equals.  If you dont put "quotes" around the number, then it sets to a numeric type.  If you put "quotes" around a number, it sets it to a string.

So how do you make sure a $_POST variable equals a string like:

$Input = $_POST['inputbox'];

 

^ that should be string not numeric otherwise it wont allow me to do the string combining..

[revraz]

$Input = (string)$_POST['inputbox'];

Everything sent via $_POST or $_GET is considered a string.
