To access a variable outside of a function in PHP, you can simply use the global keyword. For example:
1 2 3 4 5 6 7 8 |
$x = 10; function myFunction() { global $x; echo $x; } myFunction(); // outputs 10 |
Alternatively, you can use the $GLOBALS
array to access global variables from within a function. The $GLOBALS
array is an associative array that contains a reference to all variables that are currently defined in the global scope. For example:
1 2 3 4 5 6 7 |
$x = 10; function myFunction() { echo $GLOBALS['x']; } myFunction(); // outputs 10 |
Keep in mind that global variables can be overridden by local variables with the same name, so it's generally a good idea to avoid using global variables if possible.
