PHP Variables

if you are a programmer ,php have a new idea to you.You don't have to determine the type of variable.What you do is just giving the value to variable.
like that $variable_name= value;
just like that , not integer or string before variable name .

variable example

Code:

<?php
$massage= "my luck number is ";
$mynumber = 4;
  echo "$massage  $mynumber";
?>

the output is :

Code:

my luck number is 4

There some conventions with variables names :

PHP variables must start with a letter or underscore "_".
PHP variables may only be comprised of alpha-numeric characters and underscores. a-z, A-Z, 0-9, or _ .
Variables with more than one word should be separated with underscores. $my_variable
Variables with more than one word can also be distinguished with capitalization. $myVariable
