I have been using php for about 12 months and i have never had to declare a variable as either a Interger or String etc, how come i don't have to do this in php when i have used other languages i have always had to declare them first. Y is php different.:confused:

In PHP this is done automatically. PHP does not support explicit type definition in variable declaration. In other languages like c it is required to define before using the variable. It's type is determined in PHP by the context in which that variable is used.

For Ex.
If you assign a string value to variable $temp, it becomes a string. If you then assign an integer value to it, it becomes an integer.

There are still variable eval functions

And there are a few cast functions
