Is it recommended to use constants for values that need to be manually changed frequently in PHP?

Using constants for values that need to be manually changed frequently in PHP is not recommended. Constants are meant to be used for values that do not change during the execution of the script. If a value needs to be updated frequently, it is better to use a variable instead. This allows for easier maintenance and modification of the value without having to modify the code itself.

// Using variables instead of constants for values that need to be manually changed frequently
$myValue = 10;

// Use $myValue throughout your code where the value needs to be used
echo $myValue;
