The What
It’s available in PHP 4, 5, and 7.
Description
This construct loads the specified file if that file exists. It will only load it one time. Therefore, if it’s called again, it checks in memory to determine if the file has already been loaded previously.
Unlike require_once, if the file does not exist, then a E_WARNING warning error is thrown.
The path can be omitted. In this case, PHP will search in the same directory for the file.
If the path is provided, whether it’s an absolute or relative path, PHP searches based upon that path.
The code contained within the loaded file will inherit the local variable scope on the line where it’s loaded.
Parameters
file- The file to be loaded.
Return Values
This function a true.
Your functions are bloated. Put them on a diet. Think "skinny" and "as few lines as possible."
More coming soon…keep checking back.
