Changing Type with settype()

   <source lang="html4strict">

<html> <body>

<?php 

   $undecided = 3.14;
   print gettype( $undecided ); 
   print " -- $undecided
";
   settype( $undecided, string );
   print gettype( $undecided ); 
   print " -- $undecided
";
   settype( $undecided, int );
   print gettype( $undecided ); 
   print " -- $undecided
";
   settype( $undecided, double );
   print gettype( $undecided ); 
   print " -- $undecided
";
   settype( $undecided, bool );
   print gettype( $undecided ); 
   print " -- $undecided
";

?>

Force a variable into a specific data type

   <source lang="html4strict">

<?php 

   $mynumber = "1.03"; 
   $mynumber = settype ($mynumber ,"integer"); 
   echo $mynumber . "
"; 
   echo (int) $mynumber;

?> 

 </source>
