The derivative of a constant is always zero and the derivative of a function depends upon what kind of function it is (for example, you candifferentiateexponents with thepower rule). Intuitively, you might think that a constant multiplied by a function is zero, because the derivative of a co...
to prevent errors, you can use the following function to get the value of a constant.<?phpfunction getconst($const){ return (defined($const)) ? constant($const) : null;}?>Finally you can check the value with<?phpif(getconst('FOO') === 'bar'){...}?>It's simply shorter. up ...

Named constants When specifying the value of a named constant, theCONSTkeyword itself is optional. That is, the constant value can be specified with or without theCONSTkeyword. The parameter must be a literal, figurative constant, or built-in-function. The constant may be continued on subsequent...
