variable returns 0

[russthebarber]

I'm having problems with a php variable I am getting from a CMS program (Contao).

 

echo $myPageVar // returns 17
echo gettype($myPageVar); //returns string

 

This seems OK but whenever i convert to an integer I get a value of 0. When I try to use the variable in a condition it also returns false.

 

if ($myPageVar == "17")
{
      //returns false
}

 

How do I convert $myPageVar to a useable variable with  value = 17?

or $myPageVar = (int) $myPageVar;

or or $myPageVar = (int) $myPageVar{0}. $myPageVar{1};

Hi, thanks all for the help. I tried various ways of converting to an INT with no success. Now I know the problem. My variable, although it outputs "string" when type tested, is actually an array starting with two curly braces and that is what is confusing php. I've got it sorted now. In case this helps any Contao users trying to write php with contao variables.....

 

Don't do this:

 

$myPageVar = '{{page::id}}';//gives you something php doesn't understand 

 

Do this:

 

$myPageVar = $this->replaceInsertTags( '{{page::id}}' ); //for a php friendly variable
