There is no declaration of PHP Variables as such.
A Variable is defined with its first assignment.
for eg.
$a = 5; // This is a declaration.
Note if you try to use an un-initialized variable. PHP gives a warning. "PHP Notice: Undefined
variable"
To avoid this you can check if a variableis defined by using isset command.
