I'm relatively new to PHP and I'm encountering an issue with checking if a variable is an integer. I have a situation where I need to verify if a particular variable contains an integer value or not.
To give you some context, I'm working on a form validation script where users can enter various types of data, including numbers. I want to make sure that when the user inputs a value, it is indeed a valid integer.
I've tried using the is_int() function, but it doesn't seem to work as expected. Is there any other method or syntax that I should be using for this purpose? It would be great if someone could guide me on how to properly check if a variable is an integer in PHP.
Any help or insight would be much appreciated. Thanks in advance!
