In order to attempt to solve error "PHP Fatal error: Cannot redeclare", here are a few things to consider:
- You may have the function declared in seperate files.
- You may have the function declared twice in the same file
- The file with the function might have been included twice
use include_once or require_once when including your file
- The function might have already been a PHP built in function
For intance, the function checkDate() is already a PHP function.
Therefore don't do this:
function checkDate(){
$currentDay = date('Y-m-d');
return $currentDay;
}
echo checkDate();
