PHP include () call file simple instance _php tutorial

Include ' include.php tutorial '; referencing include.php files

echo A ();

?>

include.php files are as follows

Create include.php for other files to invoke
function A ()//define functions A
{
b (); Call function B in function a
}
function B ()//define functions B
{
C (); Calling function C in function b

function C ()//define functions C

Other tips:

When a file is called using the Require () statement, the Require () statement outputs an error message if the file is not found, and immediately terminates the processing of the script. The include () statement outputs a warning when no file is found and does not terminate the processing of the script
