I hope you're doing well. I am working on a PHP project and I have a string variable that I need to convert to uppercase. Could someone please guide me on how to achieve this?
I have already tried using the strtolower() function, but that only converts the string to lowercase. I need the whole string to be in uppercase. Is there a specific function in PHP that handles this?
I would greatly appreciate any help or suggestions you can provide. Thank you in advance!
