The function is used to determine the current page URL, which can be useful for generating links or performing other operations that are specific to the current page.
This function does not take any arguments
||Description of Returned Data
||Returns the name of the current file being executed.
The currentFile function first declares two global variables, $abs_us_root
, which are used to determine the server and URL roots of the UserSpice application. The function then uses the explode function to split the $_SERVER
['PHP_SELF'] variable (which contains the current file path) into an array of directory names. The function then iterates over this array to determine the current file being executed.
The function checks if the z_us_root.php file exists in the $abs_us_root
directory. If the file is found, the function breaks out of the loop and returns the name of the current file. If the file is not found, the function continues to iterate over the directory names until it finds the file or reaches the end of the array.
Finally, the function uses the substr function to extract the current file name from the $_SERVER
Here is an example of how the currentFile function can be used:
In this example, the currentFile function is called to retrieve the name of the current file. The name of the current file is then used to generate a link to the same page. The $us_url_root
variable is used to determine the root URL of the UserSpice application.
