Variable Declare


  • PHP variable must begin with a “$” sign.
  • Case-sensitive ($Boo!=$b00 !=$BOo)
  • Global and locally-scoped variable
            Global variable can be used anywhere
            Local variable restricted to a function or class
  • certain variable names reserved by PHP
            Form variable ($_POST,$_GET)
            Server variable ($_SERVER)
            Etc.



Example:-
<?php
$value=25;
$name=”Castor Classes”;
$value=($value*8);
echo “$name”;
echo $name,$value;
?>

OutPut:-
Castor ClassesCastor Classes200

Here, $value is use for integer variable and $name is string variable.
