Hi I’m using CakePHP and I’m wondering do you guys puts isset() or !empty() around all of your variables in the views? Or should I depend on the data validation? What would be the suggested solution?

I think you should know the differences between
issetandemptyand use the one that fulfills your needs.emptywill returnFALSEif the variable has a non-empty and non-zero value.The following values are considered to be empty:
""(an empty string)0(0 as an integer)"0"(0 as a string)NULLFALSEarray()(an empty array)var $var;(a variable declared, but without a value in a class)On the other hand
issetwill returnFALSEif the variable does not exist or has been unset withunset(), or the variable has been set toNULL.
