PHP Variables Scope

In PHP, variables can be declared anywhere in the script.

The scope of a variable is the part of the script where the variable can be referenced/used.

PHP has three different variable scopes:

Global and Local Scope

A variable declared outside a function has a GLOBAL SCOPE and can only be accessed outside a function:

Example

Variable with global scope:

function myTest() // using x inside this function will generate an error
echo «

Variable x inside function is: $x

«;
>
myTest();

echo «

Variable x outside function is: $x

«;
?>

A variable declared within a function has a LOCAL SCOPE and can only be accessed within that function:

Example

Variable with local scope:

function myTest() $x = 5; // local scope
echo «

Variable x inside function is: $x

«;
>
myTest();

// using x outside the function will generate an error
echo «

Variable x outside function is: $x

«;
?>

You can have local variables with the same name in different functions, because local variables are only recognized by the function in which they are declared.

PHP The global Keyword

The global keyword is used to access a global variable from within a function.

To do this, use the global keyword before the variables (inside the function):

Example

function myTest() global $x, $y;
$y = $x + $y;
>

myTest();
echo $y; // outputs 15
?>

PHP also stores all global variables in an array called $GLOBALS[index] . The index holds the name of the variable. This array is also accessible from within functions and can be used to update global variables directly.

The example above can be rewritten like this:

Example

function myTest() $GLOBALS[‘y’] = $GLOBALS[‘x’] + $GLOBALS[‘y’];
>

myTest();
echo $y; // outputs 15
?>

PHP The static Keyword

Normally, when a function is completed/executed, all of its variables are deleted. However, sometimes we want a local variable NOT to be deleted. We need it for a further job.

To do this, use the static keyword when you first declare the variable:

Example

Then, each time the function is called, that variable will still have the information it contained from the last time the function was called.

Note: The variable is still local to the function.
